Post Syndicated from Molly Clancy original https://www.backblaze.com/blog/whats-the-diff-hybrid-cloud-vs-multi-cloud/

For as often as the terms multi-cloud and hybrid cloud get misused, it’s no wonder the concepts put a lot of very smart heads in a spin. The differences between a hybrid cloud and a multi-cloud strategy are simple, but choosing between the two models can have big implications for your business.

In this post, we’ll explain the difference between hybrid cloud and multi-cloud, describe some common use cases, and walk through some ways to get the most out of your cloud deployment.

What’s the Diff: Hybrid Cloud vs. Multi-cloud

Both hybrid cloud and multi-cloud strategies spread data over, you guessed it, multiple clouds. The difference lies in the type of cloud environments—public or private—used to do so. To understand the difference between hybrid cloud and multi-cloud, you first need to understand the differences between the two types of cloud environments.

A public cloud is operated by a third party vendor that sells data center resources to multiple customers over the internet. Much like renting an apartment in a high rise, tenants rent computing space and benefit from not having to worry about upkeep and maintenance of computing infrastructure. In a public cloud, your data may be on the same server as another customer, but it’s virtually separated from other customers’ data by the public cloud’s software layer. Companies like Amazon, Microsoft, Google, and us here at Backblaze are considered public cloud providers.

A private cloud, on the other hand, is akin to buying a house. In a private cloud environment, a business or organization typically owns and maintains all the infrastructure, hardware, and software to run a cloud on a private network.

Private clouds are usually built on-premises, but can be maintained off-site at a shared data center. You may be thinking, “Wait a second, that sounds a lot like a public cloud.” You’re not wrong. The key difference is that, even if your private cloud infrastructure is physically located off-site in a data center, the infrastructure is dedicated solely to you and typically protected behind your company’s firewall.

What Is Hybrid Cloud Storage?

A hybrid cloud strategy uses a private cloud and public cloud in combination. Most organizations that want to move to the cloud get started with a hybrid cloud deployment. They can move some data to the cloud without abandoning on-premises infrastructure right away.

A hybrid cloud deployment also works well for companies in industries where data security is governed by industry regulations. For example, the banking and financial industry has specific requirements for network controls, audits, retention, and oversight. A bank may keep sensitive, regulated data on a private cloud and low-risk data on a public cloud environment in a hybrid cloud strategy. Like financial services, health care providers also handle significant amounts of sensitive data and are subject to regulations like the Health Insurance Portability and Accountability Act (HIPAA), which requires various security safeguards where a hybrid cloud is ideal.

A hybrid cloud model also suits companies or departments with data-heavy workloads like media and entertainment. They can take advantage of high-speed, on-premises infrastructure to get fast access to large media files and store data that doesn’t need to be accessed as frequently—archives and backups, for example—with a scalable, low-cost public cloud provider.

Hybrid Cloud

What Is Multi-cloud Storage?

A multi-cloud strategy uses two or more public clouds in combination. A multi-cloud strategy works well for companies that want to avoid vendor lock-in or achieve data redundancy in a failover scenario. If one cloud provider experiences an outage, they can fall back on a second cloud provider.

Companies with operations in countries that have data residency laws also use multi-cloud strategies to meet regulatory requirements. They can run applications and store data in clouds that are located in specific geographic regions.

Ways to Make Your Cloud Storage More Efficient

Whether you use hybrid cloud storage or multi-cloud storage, it’s vital to manage your cloud deployment efficiently and manage costs. To get the most out of your cloud strategy, we recommend the following:

• Know your cost drivers. Cost management is one of the biggest challenges to a successful cloud strategy. Start by understanding the critical elements of your cloud bill. Track cloud usage from the beginning to validate costs against cloud invoices. And look for exceptions to historical trends (e.g., identify departments with a sudden spike in cloud storage usage and find out why they are creating and storing more data).
• Identify low-latency requirements. Cloud data storage requires transmitting data between your location and the cloud provider. While cloud storage has come a long way in terms of speed, the physical distance can still lead to latency. The average professional who relies on email, spreadsheets, and presentations may never notice high latency. However, a few groups in your company may require low latency data storage (e.g., HD video editing). For those groups, it may be helpful to use a hybrid cloud approach.
• Optimize your storage. If you use cloud storage for backup and records retention, your data consumption may rise significantly over time. Create a plan to regularly clean your data to make sure data is being correctly deleted when it is no longer needed.
• Prioritize security. Investing up-front time and effort in a cloud security configuration pays off. At a minimum, review cloud provider-specific training resources. In addition, make sure you apply traditional access management principles (e.g., deleting inactive user accounts after a defined period) to manage your risks.

How to Choose a Cloud Strategy

To decide between hybrid cloud storage and multi-cloud storage, consider the following questions:

• Low latency needs. Does your business need low latency capabilities? If so, a hybrid cloud solution may be best.
• Geographical considerations. Does your company have offices in multiple locations and countries with data residency regulations? In that case, a multi-cloud storage strategy with data centers in several countries may be helpful.
• Regulatory concerns. If there are industry-specific requirements for data retention and storage, these requirements may not be fulfilled equally by all cloud providers. Ask the provider how exactly they help you meet these requirements.
• Cost management. Pay close attention to pricing tiers at the outset, and ask the provider what tools, reports, and other resources they provide to keep costs well managed.

Post Syndicated from Molly Clancy original https://www.backblaze.com/blog/ransomware-economy/

Ransomware continues to proliferate for a simple reason—it’s profitable. And it’s profitable not just for the ransomware developers themselves—they’re just one part of the equation—but for a whole ecosystem of players who make up the ransomware economy. To understand the threats to small and medium-sized businesses (SMBs) and organizations today, it’s important to understand the scope and scale of what you’re up against.

Today, we’re digging into how the ransomware economy operates, including the broader ecosystem and the players involved, emerging threats to SMBs, and the overall financial footprint of ransomware worldwide.

Top Ransomware Syndicates in Operation Today

Cybercriminals have long been described as operating in “gangs.” The label conjures images of hackers furiously tapping away at glowing workstations in a shadowy warehouse. But the work of the ransomware economy today is more likely to take place in a boardroom than a back alley. Cybercriminals have graduated from gangs to highly complex organized crime syndicates that operate ransomware brands as part of a sophisticated business model.

Operators of these syndicates are just as likely to be worrying about user experience and customer service as they are with building malicious code. A look at the branding on display on some syndicates’ leak sites makes the case plain that these groups are more than a collective of expert coders—they’re savvy businesspeople.

Ransomware operators are often synonymous with the software variant they brand, deploy, and sell. Many have rebranded over the years or splintered into affiliated organizations. Some of the top ransomware brands operating today, along with high profile attacks they have carried out, are shown in the infographic below:

The groups shown above do not constitute an exhaustive list. In June 2021, FBI Director Christopher Wray stated that the FBI was investigating 100 different ransomware variants and new ones pop up everyday. While some brands have existed for years (Ryuk, for example), the list is also likely obsolete as soon as it’s published. Ransomware brands bubble up, go bust, and reorganize, changing with the cybersecurity tides.

Chainalysis, a blockchain data platform, published their Ransomware 2021: Critical Mid-year Update that shows just how much brands fluctuate year to year and, they note, even month to month:

How Ransomware Syndicates Operate

Ransomware operators may appear to be single entities, but there is a complex ecosystem of suppliers and ancillary providers behind them that exchange services with each other on the dark web. The flowchart below illustrates all the players and how they interact:

Dark Web Service Providers

Cybercrime “gangs” could once be tracked down and caught like the David Levi Phishing Gang that was investigated and prosecuted in 2005. Today’s decentralized ecosystem, however, makes going after ransomware operators all the more difficult. These independent entities may never interact with each other outside of the dark web where they exchange services for cryptocurrency:

• • Botmasters: Create networks of infected computers and sell access to those compromised devices to threat actors.
  • Access Sellers: Take advantage of publicly disclosed vulnerabilities to infect servers before the vulnerabilities are remedied, then advertise and sell that access to threat actors.

• Operators: The entity that actually carries out the attack with access purchased from botmasters or access sellers and software purchased from developers or developed in-house. May employ a full staff, including customer service, IT support, marketing, etc. depending on how sophisticated the syndicate is.
• Developers: Write the ransomware software and sell it to threat actors for a cut of the ransom.
• Packer Developers: Add protection layers to the software, making it harder to detect.
• Analysts: Evaluate the victim’s financial health to advise on ransom amounts that they’re most likely to pay.
• Affiliates: Purchase ransomware as a service from operators/developers who get a cut of the ransom.
• Negotiating Agents: Handle interactions with victims.
• Laundering Services: Exchange cryptocurrency for fiat currency on exchanges or otherwise transform ransom payments into usable assets.

Victim-side Service Providers

Beyond the collection of entities directly involved in the deployment of ransomware, the broader ecosystem includes other players on the victim’s side, who, for better or worse, stand to profit off of ransomware attacks. These include:

• Incident response firms: Consultants who assist victims in response and recovery.
• Ransomware brokers: Brought in to negotiate and handle payment on behalf of the victim and act as intermediaries between the victim and operators.
• Insurance providers: Cover victims’ damages in the event of an attack.
• Legal counsel: Often manage the relationship between the broker, insurance provider, and victim, and advise on ransom payment decision-making.

Are Victim-side Providers Complicit?

While these providers work on behalf of victims, they also perpetuate the cycle of ransomware. For example, insurance providers that cover businesses in the event of a ransomware attack often advise their customers to pay the ransom if they think it will minimize downtime as the cost of extended downtime can far exceed the cost of a ransom payment. This becomes problematic for a few reasons:

• First, paying the ransom incentivizes cybercriminals to continue plying their trade.
• Second, as Colonial Pipeline discovered, the decryption tools provided by cybercriminals in exchange for ransom payments aren’t to be trusted. More than a month after Colonial paid the $4.4 million ransom and received a decryption tool from the hackers, CEO Joseph Blount testified before Congress that recovery from the attack was still not complete. After all that, they had to rely on recovering from their backups anyway.

The Emergence of Ransomware as a Service

In the ransomware economy, operators and their affiliates are the threat actors that carry out attacks. This affiliate model where operators sell ransomware as a service (RaaS) represents one of the biggest threats to SMBs and organizations today.

Cybercrime syndicates realized they could essentially license and sell their tech to affiliates who then carry out their own misdeeds empowered by another criminal’s software. The syndicates, affiliates, and other entities each take a portion of the ransom.

Operators advertise these partner programs on the dark web and thoroughly vet affiliates before bringing them on to filter out law enforcement posing as low-level criminals. One advertisement by the REvil syndicate noted, “No doubt, in the FBI and other special services, there are people who speak Russian perfectly, but their level is certainly not the one native speakers have. Check these people by asking them questions about the history of Ukraine, Belarus, Kazakhstan or Russia, which cannot be googled. Authentic proverbs, expressions, etc.”

Though less sophisticated than some of the more notorious viruses, these “as a service” variants enable even amateur cybercriminals to carry out attacks. And they’re likely to carry those attacks out on the easiest prey—small businesses who don’t have the resources to implement adequate protections or weather extended downtime.

Hoping to increase their chances of being paid, low-level threat actors using RaaS typically demanded smaller ransoms, under $100,000, but that trend is changing. Coveware reported in August 2020 that affiliates are getting bolder in their demands. They reported the first six-figure payments to the Dharma ransomware group, an affiliate syndicate, in Q2 2020.

The one advantage savvy business owners have when it comes to RaaS: attacks are high volume (carried out against many thousands of targets) but low quality and easily identifiable by the time they are widely distributed. By staying on top of antivirus protections and detection, business owners can increase their chances of catching the attacks before it’s too late.

The Financial Side of the Ransomware Economy

So, how much money do ransomware crime syndicates actually make? The short answer is that it’s difficult to know because so many ransomware attacks go unreported. To get some idea of the size of the ransomware economy, analysts have to do some sleuthing.

Chainalysis tracks transactions to blockchain addresses linked to ransomware attacks in order to capture the size of ransomware revenues. In their regular reporting on the cybercrime cryptocurrency landscape, they showed that the total amount paid by ransomware victims increased by 311% in 2020 to reach nearly $350 million worth of cryptocurrency. In May, they published an update after identifying new ransomware addresses that put the number over $406 million. They expect the number will only continue to grow.

Similarly, threat intel company, Advanced Intelligence, and cybersecurity firm, HYAS, tracked Bitcoin transactions to 61 addresses associated with the Ryuk syndicate. They estimate that the operator may be worth upwards of $150 million alone. Their analysis sheds some light on how ransomware operators turn their exploits and the ransoms paid into usable cash.

Extorted funds are gathered in holding accounts, passed to money laundering services, then either funneled back into the criminal market and used to pay for other criminal services or cashed out at real cryptocurrency exchanges. The process follows these steps, as illustrated below:

• The victim pays a broker.
• The broker converts the cash into cryptocurrency.
• The broker pays the ransomware operator in cryptocurrency.
• The ransomware operator sends the cryptocurrency to a laundering service.
• The laundering service exchanges the coins for fiat currency on cryptocurrency exchanges like Binance and Huobi.

In an interesting development, the report found that Ryuk actually bypassed laundering services and cashed out some of their own cryptocurrency directly on exchanges using stolen identities—a brash move for any organized crime operation.

Protecting Your Company From Ransomware

Even though the ransomware economy is ever-changing, having an awareness of where attacks come and the threats you’re facing can prepare you if you ever face one yourself. To summarize:

• Ransomware operators may seem to be single entities, but there’s a broad ecosystem of players behind them that trade services on the dark web.
• Ransomware operators are sophisticated business entities.
• RaaS enables even low-level criminals to get in the game.
• Ransomware operators raked in at least $406 million in 2020, and likely more than that, as many ransomware attacks and payments go unreported.

Post Syndicated from Amrit Singh original https://www.backblaze.com/blog/developers-get-ec2-alternative-with-vultr-cloud-compute-and-bare-metal/

The old saying, “birds of a feather flock together,” couldn’t be more true of the latest addition to the Backblaze partner network. Today, we announce a new partnership with Vultr—the largest privately-owned, global hyperscale cloud—to serve developers and businesses with infrastructure as a service that’s easier to use and lower cost than perhaps better known alternatives.

With the Backblaze + Vultr combination, developers now have the ability to connect data stored in Backblaze B2 with virtualized cloud compute and bare metal resources in Vultr—providing a compelling alternative to Amazon S3 and EC2. Each Vultr compute instance includes a fixed amount of bandwidth, meaning that developers can easily transfer data between Vultr’s 17 global locations and Backblaze at no additional cost.

In addition to replacing AWS EC2, Vultr’s complete product line also offers load balancers and block storage which can seamlessly replace Amazon Elastic Load Balancing (ELB) and Elastic Block Storage (EBS).

With this partnership, developers of any size can avoid vendor lock-in, access best of breed services, and do more with the data they have stored in the cloud with ease, including:

• Running analysis on stored data.
• Deploying applications and storing application data.
• Transcoding media and provisioning origin storage for streaming and video on-demand applications.

Backblaze + Vultr: Better Together

Vultr’s ease of use and comparatively low costs have motivated more than 1.3 million developers around the world to use its service. We recognized a shared culture in Vultr, which is why we’re looking forward to seeing what our joint customers can do with this partnership. Like Backblaze, Vultr was founded with minimal outside investment. Both services are transparent, affordable, simple to start without having to talk to sales (although sales support is only a call or email away), and, above all, easy. Vultr is on a mission to simplify deployment of cloud infrastructure, and Backblaze is on a mission to simplify cloud storage.

Rather than trying to be everything for everyone, both businesses play to their strengths, and customers get the benefit of working with unconflicted partners.

Vultr’s pricing often comes in at half the cost of the big three—Amazon, Google, and Microsoft—and with Vultr’s bundled egress, we’re working together to alleviate the burden of bandwidth costs, which can be disproportionately huge for small and medium-sized businesses.

“The Backblaze-Vultr partnership means more developers can build the flexible tech stacks they want to build, without having to make needlessly tough choices between access and affordability,” said Shane Zide, VP of Global Partnerships at Vultr. “When two companies who focus on ease of use and price performance work together, the whole is greater than the sum of the parts.”

Fly Higher With Backblaze B2 + Vultr

Existing Backblaze B2 customers now have unfettered access to compute resources with Vultr, and Vultr customers can connect to astonishingly easy cloud storage with Backblaze B2. If you’re not yet a B2 Cloud Storage customer, create an account to get started in minutes. If you’re already a B2 Cloud Storage customer, click here to activate an account with Vultr.

For developers looking to do more with their data, we welcome you to join the flock. Get started with Backblaze B2 and Vultr today.

Post Syndicated from Molly Clancy original https://www.backblaze.com/blog/optimizing-website-performance-with-a-cdn/

If you’ve ever wondered how a content delivery network (CDN) works, here’s a decent analogy… For most of the year, I keep one, maybe two boxes of tissues in the house. But, during allergy season, there’s a box in every room. When pollen counts are up, you need zero latency between sneeze and tissue deployment.

Instead of tissues in every room of the house, a CDN has servers in every corner of the globe, and they help reduce latency between a user’s request and when the website loads. If you want to make sure your website loads quickly no matter who accesses it, a CDN can help. Today, we’ll dig into the benefits of CDNs, how they work, and some common use cases with real-world examples.

What Is a CDN?

According to Cloudflare, one of the market leaders in CDN services, a CDN is “a geographically distributed group of servers which work together to provide fast delivery of internet content.” A CDN speeds up your website performance by temporarily keeping your website content on servers that are closer to end users. This is known as caching.

When someone in Australia visits your website that’s hosted in New York City, instead of fetching content like images, video, HTML pages, javascript files, etc. all the way from the the “origin store” (the server where the main, original website lives in the Big Apple), the CDN fetches content from an “edge server” that’s geographically closer to the end user at the edge of the network. Your website loads much faster when the content doesn’t have to travel halfway around the world to reach your website visitors.

How Do CDNs Work?

While a CDN does consist of servers that host website content, a CDN cannot serve as a web host itself一you still need traditional web hosting to operate your website. The CDN just holds your website content on servers closer to your end users. It refers back to the main, original website content that’s stored on your origin store in case you make any changes or updates.

Your origin store could be an actual, on-premises server located wherever your business is headquartered, but many growing businesses opt to use cloud storage providers to serve as their origin store. With cloud storage, they can scale up or down as website content grows and only pay for what they need rather than investing in expensive on-premises servers and networking equipment.

The CDN provider sets up their edge servers at internet exchange points, or IXPs. IXPs are points where traffic flows between different internet service providers like a highway interchange so your data can get to end users faster.

Not all of your website content will be stored on IXPs all of the time. A user must first request that website content. After the CDN retrieves it from the origin store to whatever server is nearest to the end user, it keeps it on that server as long as the content continues to be requested. The content has a specific “time to live,” or TTL, on the server. The TTL specifies how long the edge server keeps the content. At a certain point, if the content has not been requested within the TTL, the server will stop storing the content.

When a user pulls up website content from the cache on the edge server, it’s known as a cache hit. When the content is not in the cache and must be fetched from the origin store, it’s known as a cache miss. The ratio of hits to misses is known as the cache hit ratio, and it’s an important metric for website owners who use cloud storage as their origin and are trying to optimize their egress fees (the fees cloud storage providers charge to send data out of their systems). The better the cache hit ratio, the less they’ll be charged for egress out of their origin store.

Another important metric for CDN users is round trip time, or RTT. RTT is the time it takes for a request from a user to travel to its destination and back again. RTT metrics help website owners understand the health of a network and the speed of network connections. A CDN’s primary purpose is to reduce RTT as much as possible.

Do I Need a CDN?

CDNs are a necessity for companies with a global presence or with particularly complex websites that deliver a lot of content, but you don’t have to be a huge enterprise to benefit from a CDN. You might be surprised to know that more than half of the world’s website content is delivered by CDN, according to Akamai, one of the first providers to offer CDN services.

What Are the Benefits of a CDN?

A CDN offers a few specific benefits for companies, including:

• Faster website load times.
• Lower bandwidth costs.
• Redundancy and scalability during high traffic times.
• Improved security.

Faster website load times: Content is distributed closer to visitors, which is incredibly important for improving bounce rates. Website visitors are orders of magnitude more likely to click away from a site the longer it takes to load. The probability of a bounce increases 90% as the page load time goes from one second to five on mobile devices, and website conversion rates drop by an average of 4.42% with each additional second of load time. If an e-commerce company makes $50 per conversion and does about $150,000 per month in business, a drop in conversion of 4.42% would equate to a loss of almost $80,000 per year.

If you still think seconds can’t make that much of a difference, think again. Amazon calculated that a page load slowdown of just one second could cost it $1.6 billion in sales each year. With website content distributed closer to website users via a CDN, pages load faster, reducing bounce rates.

Lower bandwidth costs: Bandwidth costs are the costs companies and website owners pay to move their data around telecommunications networks. The farther your data has to go and the faster it needs to get there, the more you’re going to pay in bandwidth costs. The caching that a CDN provides reduces the need for content to travel as far, thus reducing bandwidth costs.

Redundancy and scalability during high traffic times: With multiple servers, a CDN can handle hardware failures better than relying on one origin server alone. If one goes down, another server can pick up the slack. Also, when traffic spikes, a single origin server may not be able to handle the load. Since CDNs are geographically distributed, they spread traffic out over more servers during high traffic times and can handle more traffic than just an origin server.

Improved security: In a DDoS, or distributed denial-of-service attack, malicious actors will try to flood a server or network with traffic to overwhelm it. Most CDNs offer security measures like DDoS mitigation, the ability to block content at the edge, and other enhanced security features.

CDN Cost and Complexity

CDN costs vary by the use case, but getting started can be relatively low or no-cost. Some CDN providers like Cloudflare offer a free tier if you’re just starting a business or for personal or hobby projects, and upgrading to Cloudflare’s Pro tier is just $20 a month for added security features and accelerated mobile load speeds. Other providers, like Fastly, offer a free trial.

Beyond the free tier or trial, pricing for most CDN providers is dynamic. For Amazon CloudFront, for example, you’ll pay different rates for different volumes of data in different regions. It can get complicated quickly, and some CDNs will want to work directly with you on a quote.

At an enterprise scale, understanding if CDN pricing is worth it is a matter of comparing the cost of the CDN to the cost of what you would have paid in egress fees. Some cloud providers and CDNs like those in the Bandwidth Alliance have also teamed up to pass egress savings on to shared users, which can substantially reduce costs related to content storage and delivery. Look into discounts like this when searching for a CDN.

Another way to evaluate if a CDN is right for your business is to look at the opportunity cost of not having one. Using the example above, an e-commerce company that makes $50 per conversion and does $150,000 of business per month stands to lose $80,000 per year due to latency issues. While CDN costs can reach into the thousands per month, the exercise of researching CDN providers and pricing out what your particular spend might be is definitely worth it when you stand to save that much in lost opportunities.

Setting up a CDN is relatively easy. You just need to create an account and connect it to your origin server. Each provider will have documentation to walk you through how to configure their service. Beyond the basic setup, CDNs offer additional features and services like health checks, streaming logs, and security features you can configure to get the most out of your CDN instance. Fastly, for example, allows you to create custom configurations using their Varnish Configuration Language, or VCL. If you’re just starting out, setting up a CDN can be very simple, but if you need or want more bells and whistles, the capabilities are definitely out there.

Who Benefits Most From a CDN?

While a CDN is beneficial for any company with broad geographic reach or a content-heavy site, some specific industries see more benefits from a CDN than others, including e-commerce, streaming media, and gaming.

E-commerce and CDN: Most e-commerce companies also host lots of images and videos to best display their products to customers, so they have lots of content that needs to be delivered. They also stand to lose the most business from slow loading websites, so implementing a CDN is a natural fit for them.

Streaming Media and CDN: Like e-commerce sites, streaming media sites host a lot of content, and need to deliver that content with speed and reliability. Anyone who’s lost service in the middle of a Netflix binge knows: buffering and dropped shows won’t cut it.

Gaming and CDN: Gaming platforms, too, have a heavy burden of graphics, images, and video to manage. They also need to deliver content fast and at speed or they risk games glitching up in the middle of a deciding moment.

In addition to the types of companies listed above, financial institutions, media properties, mobile apps, and government entities can benefit from a CDN as well. However, a CDN is not going to be right for everyone. If your audience is hyper-targeted in a specific geographic location, you likely don’t need a CDN and can simply use a geolocated web host.

Pairing CDN With Cloud Storage

A CDN doesn’t cache every single piece of data一there will be times when a user’s request will be pulled directly from the origin store. Reliable, affordable, and performant origin storage becomes critical when the cache misses content. By pairing a CDN with origin storage in the cloud, companies can benefit from the elasticity and scalability of the cloud and the performance and speed of a CDN’s edge network.

Post Syndicated from Molly Clancy original https://www.backblaze.com/blog/next-steps-for-chia-in-their-own-words/

A few weeks ago we published a post about why Backblaze chose not to farm Chia in our storage buffer. Our explanation was pretty simple: We agreed we weren’t in the game of currency speculation, so we just took the value and Netspace at the time and ran some math. In the end, it didn’t work for us, but our analysis isn’t the last word—we’re as curious as the next person as to what happens next with Chia.

The Chia Netspace slowed its exponential climb since we ran the post. At the time, it was increasing by about 33% each week. It’s now hovering between 31 and 33 exabytes, leaving us, and we presume a lot of other people, wondering what the future looks like for this cryptocurrency.

Jonmichael Hands, the VP of storage business development at Chia, reached out offering to discuss our post, and we figured he’d be a good guy to ask. So we gathered a few questions and sat down with him to learn more about what he sees on the horizon and what a wild ride it’s been so far.

Editor’s Note: This interview has been edited for length and clarity.

Q: What brought you to the Chia project?

I was involved in the beta about a year ago. It was right in the middle of COVID, so instead of traveling for work frequently, I built Chia farms in my garage and talked to a bunch of strangers on Keybase all night. At that time, the alpha version of the Chia plotter wrote six times more data than it writes today. I messaged the Chia president, saying, “You can’t release this software now. It’s going to obliterate consumer SSDs.” Prior to joining Chia, when I was at Intel, I did a lot of work on SSD endurance, so I helped Chia understand the software and how to optimize it for SSD endurance over the course of the year. Chia is an intersection of my primary expertise of storage, data centers, and cryptocurrencies—it was a natural fit, and I joined the team in May 2021.

Q: What was the outcome of that work to optimize the software?

Over the year, we got it down to about 1.3TB of writes, which is what it takes today. It’s still not a very friendly workload for consumer SSDs, and we definitely did not want people buying consumer SSDs and accidentally wearing them out for Chia. There has been a ton of community development in Chia plotters since the launch to further improve the performance and efficiency.

Q: That was a question we had, because Chia got a lot of backlash about people burning out consumer SSDs. What is your response to that criticism?

We did a lot of internal analysis to see if that was true, because we take it very seriously. So, how many SSDs are we burning out? I erred on the side of caution and assumed that 50% of the Netspace was farmed using consumer SSDs. I used the endurance calculator that I wrote for Chia on the wiki, which estimates how many plots you can write until the drive wears out. With 32 exabytes of Netspace, my math shows Chia wore out about 44,000 drives.

That seems high to me because I think consumers are smart. For the most part, I expect people have been doing their own research and buying the appropriate drives. We’ve also seen people plot on a consumer drive until it reaches a percentage of its useful life and then use it for something else. That’s a smart way to use new SSD drives—you get maximum use out of the hardware.

Companies are also offering plotting as a service. There are 50 or 60 providers who will just plot for you, likely using enterprise SSDs. So, I think 44,000 drives is a high estimate.

In 2021, there were 435 million SSD units shipped. With that many drives, how many SSD failures should we expect per year in total? We know the annualized failure rates, so it’s easy to figure out. Even in a best case scenario, I calculated there were probably 2.5 million SSD failures in 2021. If we created 44,000 extra failures, and that’s the high end, we’d only be contributing 1.5% of total failures.

Q: So, do you believe the e-waste argument is misplaced?

I’ve learned a lot about e-waste in the last few weeks. I talked to some e-waste facilities, and the amount of e-waste that SSDs create is small compared to other component parts, which is why SSD companies haven’t been attacked for e-waste before. They’re light and they don’t contain too many hazardous materials, comparatively. Most of them last five to 10 years as well. So we don’t believe there’s a large contribution from us in that area.

On the other hand, millions of hard drives get shredded each year, mostly by hyperscale data centers because end customers don’t want their data “getting out,” which is silly. I’ve talked to experts in the field, and I’ve done a lot of work myself on sanitization and secure erase and self-encrypting drives. With self-encrypting drives, you can basically instantly wipe the data and repurpose the drive for something else.

The data is erasure coded and encrypted before it hits the drive, then you can securely wipe the crypto key on the drive, making the data unreadable. Even then, tens of millions of drives are crushed every year, many of them for security reasons well before the end of their useful life. We think there’s an opportunity among those wasted drives.

Our team has a lot of ideas for how we could use Chia to accelerate markets for third-party recycled and renewed drives to get them back in the hands of Chia farmers and create a whole circular economy. If we’re successful in unlocking that storage, that will bring the cost of storage down. It will be a huge win for us and put us solidly on the right side of the e-waste issue.

Q: Did you expect the boom that happened earlier this summer and the spikes it created in the hard drive market?

Everybody at the company had their own Netspace model. My model was based off of the hard drive supply-demand sufficiency curve. If the market is undersupplied, prices go up. If the market’s vastly undersupplied, prices go up exponentially.

IDC says 1.2 zettabytes of hard drives are shipped every year, but the retail supply of HDDs is not very big. My model said when we hit 1% of the total hard drive supply for the year, prices are going to go up about 15%. If we hit 2% or 3%, prices will go up 30% to 40%. It turns out I was right that hard drive prices would go up, but I was wrong about the profitability.

It was the perfect black swan event. We launched the network on March 19 at 120 petabytes. Bitcoin was at an all-time high in April. We had this very low Netspace and this very high price. It created insane profitability for early farmers. Small farms were making $150,000 a day. People were treating it like the next Bitcoin, which we didn’t expect.

We went from 120 petabytes when we launched the network to 30 exabytes three months later. You can imagine I was a very popular guy in May. I was on the phone with analysts at Western Digital and Seagate almost every day talking about what was going to happen. When is it going to stop? Is it just going to keep growing forever?

It’s not shocking that it didn’t last long. At some point profitability gets impacted, and it starts slowing down.

Q: Where do you see hard drive demand going from here?

If the price doubles or triples in a very short amount of time, we might see a rush to go buy new hardware in the short term, but it will self-correct quickly. We’ll see Netspace acceleration in proportion. We predict the next wave of growth will come from smaller farmers and pools.

Bram [Cohen, the founder of Chia] hypothesized that underutilized storage space is ubiquitous. The majority of people aren’t using all of their hard drive space. IDC believes there’s about 500 exabytes of underutilized storage space sitting out in the world, so people have this equipment already. They don’t have to rush out and buy new hardware. That will largely be true for the next six months of growth. The first wave of growth was driven by new purchases. The next wave, and probably for the long term for Chia, will largely be driven by people who already have storage because the marginal cost is basically zero.

The demand for storage, overall, is increasing 20% to 30% every year, and hard drives are not getting 20% to 30% bigger every year. At some point, this inevitable squeeze was always going to happen where demand for storage exceeds supply. We want to figure out how we can grow sustainably and not impact that.

We have an interesting use case for old used drives, so we’re trying to figure out what the model is. There are certainly people who want to farm Chia on the enterprise scale, but it’s just not going to be cost-competitive to buy new drives long-term.

Q: Between the big enterprise farmers and the folks just happy to farm a few plots, do you have a preference?

Today, 37% of people are farming 10-50TB and 26% are farming 50-150TB. The remaining are big farmers. Technically, the smaller the farmer, the better. That means that we’re more decentralized. Our phase one was to build out the protocol and the framework for the most decentralized, secure blockchain in the world. In under three months, we’ve actually done that. One of the metrics of decentralization is how many full nodes you have. We’re approaching 350,000 full nodes. Just by pure metrics of decentralization we believe we are the most decentralized blockchain on the planet today.

Note: As of August 12, 2021, peak Bitcoin had 220K validators and now has about 65K. Chia’s peak was about 750K and it hovers around 450K.

In that respect, farming is actually one of the least interesting things we’re doing. It is a way to secure the network, and that’s been very novel. Today, if you want to launch a 51% attack, you have to buy 15 exabytes and get them up on the network. We think there’s definitely less than 100 data centers in the world that can host that many exabytes. Basically, the network has to be big enough where it can’t be attacked, and we think it’s there now. It’s very hard to attack a 30 exabyte network.

Q: We know you can’t speculate on future performance, but what does the future look like for Chia?

Our vision is to basically flip Ethereum within three years. Part of the business model will be having the support teams in place to help big financial institutions utilize Chia. We also think having a dedicated engineering team who are paid salaries is a good thing.

Our president thinks we’ll be known for Chialisp, which is the smart on-chain programming model. In the same way that everything’s a file in Linux, everything’s a coin in Chia. You can create what we call “Coloured Coins” or assets on the blockchain. So, you could tokenize a carbon credit. You could tokenize a Tesla stock. You can put those on the Chia blockchain and it just lives as a coin. Because it’s a coin, it natively swaps and is compatible with everything else on the blockchain. There’s no special software needed. Somebody could send it to another person with the standard Chia wallet because everything’s already integrated into the software. It’s very powerful for decentralized exchanges for some of this assetization and tokenization of different types of collateral on the blockchain.

Large financial institutions want to get involved with cryptocurrency, but there’s no play for them. All the financial institutions we’ve talked to have looked at Ethereum, but there are too many hacks. The code is too hard to audit. You need too much expertise to write it. And it consumes way too much energy. They’re not going to use a blockchain that’s not sustainable.

We are going to try to bridge that gap between traditional finance and the new world of cryptocurrency and decentralized finance. We think Chia can do that.

As big believers in open ecosystems, interoperability, and just making life easier for developers, Backblaze and Cloudflare share a lot—which means we’re always excited to dig into new functionality they’re providing for devs. When we heard about their new Logpush tool, I reached out to Tanushree Sharma, the product manager on this project, to learn more about why they built it, how it works with Backblaze B2 Cloud Storage, and what comes next.

Q: Tell us more about the origins of Logpush. How does it fit into the Cloudflare ecosystem and what problems is it solving for?

A: Cloudflare provides security, performance, and reliability services to customers behind our network. We analyze the traffic going through our network to perform actions such as routing traffic to the nearest data center, protecting against attacks, and blocking malicious bots. As part of providing these services for customers, we generate logs for every request in our network. Logpush makes these logs available for Enterprise customers to get visibility into their traffic, quickly and at scale.

Q: Cloudflare already offers Logpull, what’s the difference between that and Logpush?

A: Logpull requires customers to make calls to our Logpull API and then set up a storage platform and/or analytics tools to view the logs. Increasingly, we were hearing repeated use cases where customers would want to integrate with common log storage and analytics products. We also frequently heard that customers want their logs in real time or as near as possible. We decided to create Logpush to solve both these problems. Rather than the need for customers to configure and maintain a system that makes repeated API calls for the data, with Logpush, customers configure where they would like to send their logs and we push them there directly on their behalf.

Q: What makes it compelling to Cloudflare customers? Are there specific use cases you can touch on? Any light you can shed on how a beta tester used it when you first announced it?

A: Logpush makes it very easy for customers to export data. They simply set up a job using the Logpush API or with the click of a few buttons in the Cloudflare dashboard. From there, customers can combine Cloudflare logs with those of other tooling in their infrastructure, such as a SIEM or marketing tracking tools.

This combined data is very useful not only for day-to-day monitoring, but also when conducting network forensics after an attack. For example, a typical L7 DDoS attack originates from a handful of IP addresses. Customers can use platform-wide analytics to understand the activity of IP addresses from both within the Cloudflare network and other applications in their infrastructure. Platform-wide analytics are very powerful in giving customers a holistic view of their entire system.

Q: What sparked the push to support more S3-compatible storage destinations for Logpush data?

A: S3-compatible storage is becoming an industry standard for cloud storage. With the increased adoption of S3-compatible storage, we thought it would be a great spot for us to create our own endpoint to be able to serve more platforms.

Q: This isn’t the first time Backblaze and Cloudflare have worked together. In the spirit of building a better internet, we’ve helped a number of companies reduce data transfer fees via the Bandwidth Alliance. How did this affect your decision to include B2 Cloud Storage as one of these storage destinations and how is it serving Cloudflare and its customers’ needs?

A: Cloudflare values open ecosystems in technology—we believe that customers should not have to be locked in to any single provider. We started the Bandwidth Alliance to reduce or eliminate egress fees, which gives customers the ability to select a set of options that work best for them. With Backblaze as a long time Bandwidth Alliance member, including B2 Cloud Storage out of the gate was a no-brainer!

This case study on why Nodecraft made the switch from AWS S3 to Backblaze B2 Cloud Storage is a great illustration of how the Bandwidth Alliance can benefit customers.

Q: What was the process of integrating B2 Cloud Storage within the Logpush framework?

A: We worked with the great folks at Backblaze to integrate B2 Cloud Storage as a storage destination. This process began by modeling out costs, which were greatly reduced due to discounted egress costs as a result of the Bandwidth Alliance. For the S3-compatible integration, our team leveraged the AWS Go SDK to integrate with BackBlaze. Once we had verified that the integration was working, we created an intuitive UI-based workflow for our customers to make it easier for them to create and configure Logpush jobs.

Q: What can we look forward to as Logpush matures? Anything exciting on the horizon that you’d like to share?

A: One of the big areas that our team is focusing on is data sovereignty. We want customers to have control over where their data is stored and processed. We’re also working on building out Logpush by adding data sets and giving customers more customization with their logs.

Stay tuned to our Logs blog for upcoming releases!

Q: As a Cloudflare customer, where do I begin if I want to utilize Logpush? Walk us through the setup process of selecting B2 Cloud Storage as a destination for my logs.

A: Once your B2 Cloud Storage destination is set up, you can create an S3-compatible endpoint on Cloudflare’s dashboard or API by specifying the B2 Cloud Storage destination information. For a detailed walkthrough on how to create a Logpush job, take a look at our documentation on enabling S3-compatible endpoints.

Many thanks Tanushree, we’re excited to see how customers put this new tool to work.

Post Syndicated from Molly Clancy original https://www.backblaze.com/blog/how-multi-cloud-strengthens-startups/

In early startup stages, you’re developing the product, testing market fit, and refining your go-to-market strategy. Long-term infrastructure decisions may not even be on your radar, but if you want to scale beyond Series B, it pays to be planful before you’re locked in with a cloud services provider and storage costs are holding you back.

How will you manage your data? How much storage will you need to meet demand? Will your current provider continue to serve your use case? In this post, we’ll talk about how infrastructure decisions come into play in early startup development, the advantages of multi-cloud infrastructure, and best practices for implementing a multi-cloud system.

Infrastructure Planning: A Startup Timeline

Infrastructure planning becomes critical at three key points in early startup development:

• In the pre-seed and seed stages.
• When demand spikes.
• When cloud credits run out.

Pre-seed and Seed Stages

Utilizing free cloud credits through a startup incubator like AWS Activate or the Google Cloud Startup Program at this stage of the game makes sense—you can build a minimum viable product without burning through outside investment. But you can’t rely on free credits forever. As you discover your market fit, you need to look for ways of sustaining growth and ensuring operating costs don’t get out of control later. You have three options:

1. Accept that you’ll stay with one provider, and manage the associated risks—including potentially high operating costs, lack of leverage, and high barriers to exit.
2. Plan for a migration when credits expire. This means setting up your systems with portability in mind.
3. Leverage free credits and use the savings to adopt a multi-cloud approach from the start with integrated providers.

Any of these options can work. What you choose is less important than the exercise of making a thoughtful choice and planning as though you’re going to be successful rather than relying on free credits and hoping for the best.

Waiting Until Demand Spikes

Let’s say you decide to take full advantage of free credits, and the best possible outcome happens—your product takes off like wildfire. That’s great, right? Yes, until you realize you’re burning through your credits faster than expected and you have to scramble to figure out if your infrastructure can handle the demand while simultaneously optimizing spend. Especially for startups with a heavy data component like media, games, and analytics, increased traffic can be especially problematic—storage racks up, but more often, it’s egress fees that are the killer when data is being accessed frequently.

It’s not hard to find evidence of the damage that can occur when you don’t keep an eye on these costs:

That's right–it's threading time!@chrisshort's surprise @awscloud bill of $2700 looks S3 driven… https://t.co/VnXufn24iA pic.twitter.com/tKLWv5rHtW

— Corey Quinn (@QuinnyPig) July 6, 2020

The moment you’re successful can also be the moment you realize you’re stuck with an unexpected bill. Demand spikes, and cloud storage or egress overwhelms your budget. Consider the opposite scenario as well: What if your business experiences a downturn? Can you still afford to operate when cash flow takes a hit?

Waiting Until Cloud Credits Run Out

Sooner or later, free cloud credits run out. It’s extremely important to understand how the pricing model, pricing tiers, and egress costs will factor into your product offering when you get past “free.” For a lot of startups, these realities hit hard and fast—leaving developers seeking a quick exit.

It may feel like it’s too late to make any changes, but you still have options:

1. Stay with your existing provider. This approach involves conducting a thorough audit of your cloud usage and potentially bringing in outside help to manage your spend.
2. Switch cloud providers completely. Weigh the cost of moving your data altogether versus the long-term costs of staying with your current provider. The barrier to exit may be high, but breakeven may be closer than you think.
3. Adopt an agnostic, multi-cloud approach. Determine the feasibility of moving parts of your infrastructure to different cloud providers to optimize your spend.

The Multi-cloud Guide for Startups

More companies have adopted a multi-cloud strategy in recent years. A 2020 survey by IDG found that 55% of organizations currently use multiple public clouds. The shift comes on the heels of two trends. First, AWS, Google, and Microsoft are no longer the only game in town. Innovative, specialized IaaS providers have emerged over the past decade and a half to challenge the incumbents. Second, after a period where many companies had to transition to the cloud, companies launching today are built to be cloud native. Without the burden of figuring out how to move to the cloud, they can focus on how best to structure their cloud-only environments to take advantage of the benefits multi-cloud infrastructure has to offer.

The Advantages of Multi-cloud

1. Improved Reliability: When your data is replicated in more than one cloud, you have the advantage of redundancy. If one cloud goes down, you can fall back to a second.
2. Disaster Recovery: With data in multiple, isolated clouds, you’re better protected from threats. If cybercriminals are able to access one set of your data, you’re more likely to recover if you can restore from a second cloud environment.
3. Greater Flexibility and Freedom: With a multi-cloud system, if something’s not working, you have more leverage to influence changes and the ability to leave if another vendor offers better features or more affordable pricing.
4. Affordability: It may seem counterintuitive that using more clouds would cost less, but it’s true. Vendors like AWS make their services hard to quit for a reason—when you can’t leave, they can charge you whatever they want. A multi-cloud system allows you to take advantage of industry partnerships and competitive pricing among vendors.
5. Best-of-breed Providers: Adopting a multi-cloud strategy means you can work with providers who specialize in doing one thing really well rather than doing all things just…kind of okay.

The advantages of a multi-cloud system have attracted an increasing number of companies and startups, but it’s not without challenges. Controlling costs, data security, and governance were named in the top five challenges in the IDG study. That’s why it’s all the more important to consider your cloud infrastructure early on, follow best practices, and plan ways to manage eventualities.

Multi-cloud Best Practices

As you plan your multi-cloud strategy, keep the following considerations in mind:

1. Cost Management: Cost management of cloud environments is a challenge every startup will face even if you choose to stay with one provider—so much so that companies make cloud optimization their whole business model. Set up a process to track your cloud utilization and spend early on, and seek out cloud providers that offer straightforward, transparent pricing to make budgeting simpler.
2. Data Security: Security risks increase as your cloud environment becomes more complex, and you’ll want to plan security measures accordingly. Ensure you have controls in place for access across platforms. Train your team appropriately. And utilize cloud functions like encryption and Object Lock to protect your data.
3. Governance: In an early stage startup, governance is going to be relatively simple. But as your team grows, you’ll need to have clear protocols for how your infrastructure is managed. Consider creating standard operating procedures for cloud platform management and provisioning now, when it’s still just one hat your CTO is wearing.

By making thoughtful choices about your cloud infrastructure and following some basic multi-cloud best practices, you plan as though you’re going to win from the start. That means deciding early on as to whether you’ll take cloud credits and stay with one provider, plan for multi-cloud, or some mix of the two along the way.

The Tovera Backstory: Fighting Deepfakes

One morning, this story really caught my attention.

Like many technology enthusiasts, I’m familiar with deepfakes. That said, the “Pennsylvania Cheerleading Mom” story told me something: As we’ve seen time and time again, technology rapidly evolves beyond its original intended use. Sometimes for our benefit, and (unfortunately) sometimes not so much…

I realized it would only be a matter of time before this incredibly powerful technology would be in the hands of everyone—for uses good or evil. With more research, I found that (not surprisingly) the current approach to stopping misuse of the technology utilizes the same fundamental machine learning approaches powering the deepfakes themselves. It seems that what we now have is a machine learning arms race: a new model to generate deepfakes, a new model to detect them. Around and around we go.

I began thinking of approaching the deepfake problem from the other side of the coin. What if, instead of using machine learning to guess what is fake, we prove what is real? Deepfake detection models can’t provide 100% certainty today (or ever), but cryptographic authentication can. This simple idea was the genesis for Tovera.

What Does Tovera Do?

Tovera takes digital media you upload and uses existing cryptography and emerging blockchain technology to create a 100% secure validation record. When published on our platform, we can confirm (with 100% certainty) that your digital media assets are yours and haven’t been tampered with.

After working through the initial proof of concept, I had another revelation: “Hey, while we’re hitting our API whenever and wherever digital media is viewed, why don’t we return some extra stuff?” Now, not only can our users validate that their content is really theirs and hasn’t been modified, they can use the features provided by Tovera Publish to dynamically update their released digital content from our dashboard. With Tovera, any changes you make to your digital media and online presence are updated across social media platforms, websites, and devices globally—instantly.

In keeping with our mission of ensuring everyone can protect, validate, and control their online presence, we provide this technology for free with a simple sign up and onboarding process.

The Tovera Storage Journey

To provide this service, we needed to host the digital media files somewhere. Of course, you have your go-to juggernauts—Amazon, Google, and Microsoft. The problem is Tovera is a tiny startup. Having some prior startup experience, I know that spending your money and time wisely from the beginning is one of the most important things you can do.

I took one look at pricing from the “big three” cloud providers through the lens of someone who has experience buying bandwidth and storage (long story) and I thought, “Wow, this is a good business.” As has been covered on this blog and elsewhere, the storage and (especially) bandwidth markups from the big providers is, to put it mildly, significant.

Like some of you, I’ve also been a fan of Backblaze for a long time. Since it was announced, I’ve kept an eye on their B2 Cloud Storage product. So, one morning I took it upon myself to give Backblaze B2 a try.

Sign up and initial onboarding couldn’t have been easier. I found myself in the Backblaze B2 user dashboard up and running in no time. Creating application keys for my purposes was also extremely easy.

After deciding B2 Cloud Storage would work in theory, I decided to try it out in practice. As I integrated the service into Tovera, I ran into a few different vexing issues. I thought other devs might be able to benefit from my CORS troubleshooting, and so I’m outlining my experience here.

Checking the Backblaze S3 Compatible API

We make it simple for our users to upload their assets directly to our cloud storage provider. Because B2 Cloud Storage has the Backblaze S3 Compatible API, the use of presigned URLs fits the bill. This way, Tovera users can upload their digital media assets directly to Backblaze, securely, and make them available to the world via our platform.

In case you’re not familiar with the presigned URL process, the overall flow looks something like the structure laid out in this blog post.

After perusing the available documentation, I started off with the following Node.js Javascript code:

With this Javascript function, Tovera API services provide a URL for our user dashboard to instantly (and securely) upload their assets to our Backblaze account. I had read Backblaze B2 has a 100% Amazon S3 Compatible API but I was a little skeptical. Is this really going to work? Sure enough, it worked on the first attempt!

Integrating Cloudflare and Setting Up CORS

Between the Bandwidth Alliance and having dealt with DDoS attacks and shady internet stuff in general before, I’m also a big fan of Cloudflare. Fortunately, Backblaze provides guidance on how to best use B2 Cloud Storage with Cloudflare to make use of their combined power.

Once I set up Cloudflare to work with B2 Cloud Storage and the Tovera API services were returning valid, presigned URLs for clients to do a direct HTTP PUT, I tried it out in our Next.js-powered user dashboard.

Uh-oh. Dreaded CORS errors. I’ll spare you the details, but here’s where things get interesting… I don’t know about you, but CORS can be a little frustrating. LONG story short, I dug in deep, feeling a little like I was wandering around a dark room looking for the light switch.

After fumbling around a bit, I was able to piece together the following with the Backblaze B2 command line utility:

With this usage of the Backblaze B2 command line utility, we’re setting the following CORS rules on our bucket:

• Allow users to download Backblaze B2 files from anywhere using the native B2 Cloud Storage interfaces.
• Allow users to use the Backblaze S3 Compatible API to download and upload their files from anywhere with the authenticated presigned URL provided by the server side Javascript function above.

With these rules, Tovera users can use our embeddable verification links across any site they provide them to—existing websites, social media networks, and more. In other applications you may want to limit these CORS rules to what makes sense for your use case.

Focusing on What’s Important

With Backblaze B2, we at Tovera can focus on our mission of putting our digital media security, validation, and publishing functionality in the hands of as many people as possible. Tovera users can take back control of their online presence and address the many threats posed by deepfake technologies that threaten their likeness, reputation, and brand.

Kristian Kielhofner works on overall technical architecture, vision, and strategy for Tovera when he’s not out buying yet another whiteboard to scribble on. Kristian previously built, grew, and exited Star2Star Communications—a leading provider of business productivity solutions.

Post Syndicated from Molly Clancy original https://www.backblaze.com/blog/school-district-cloud-storage-solutions/

In an era when ransomware and cybersecurity attacks on K-12 schools have nearly quadrupled, backups are critical. Today, advances in cloud backup technology like immutability and Object Lock allow school districts to take advantage of the benefits of cloud infrastructure while easing security concerns about sensitive data.

School districts have increasingly adopted cloud-based software as a service applications like video conferencing, collaboration, and learning management solutions, but many continue to operate with legacy on-premises solutions for backup and disaster recovery. If your district is ready to move your backup and recovery infrastructure to the cloud, how do you choose the right cloud partners and protect your school district’s data?

This post explains the benefits school districts can realize from moving infrastructure to the cloud, considerations to evaluate when choosing a cloud provider, and steps for preparing for a cloud migration at your district.

The Benefits of Moving to the Cloud for School Districts

Replacing legacy on-premises tape backup systems or expensive infrastructure results in a number of benefits for school districts, including:

1. Reduced Capital Expenditure (CapEx): Avoid major investments in new infrastructure.
2. Budget Predictability: Easily plan for predictable, recurring monthly expenses.
3. Cost Savings: Pay as you go rather than paying for unused infrastructure.
4. Elasticity: Scale up or down as seasonal demand fluctuates.
5. Workload Efficiencies: Refocus IT staff on other priorities rather than managing hardware.
6. Centralized Backup Management: Manage your backups in a one-stop shop.
7. Ransomware Protection: Stay one step ahead of hackers with data immutability.

Reduced CapEx. On-premises infrastructure can cost hundreds of thousands of dollars or more, and that infrastructure will need to be replaced or upgraded at some point. Rather than recurring CapEx, the cloud shifts IT budgets to a predictable, monthly operating expenses (OpEx) model. You no longer have to compete with other departments for a share of the capital projects budget to upgrade or replace expensive equipment.

Budget Predictability. With cloud storage, if you can accurately anticipate data usage, you can easily forecast your cloud storage budget. Since equipment is managed by the cloud provider, you won’t face a surprise bill when something breaks.

Cost Savings. Even when on-premises infrastructure sits idle, you still pay for its maintenance, upkeep, and power usage. With pay-as-you-go pricing, you only pay for the cloud storage you use rather than paying up front for infrastructure and equipment you may or may not end up needing.

Elasticity. Avoid potentially over-buying on-premises equipment since the cloud provides the ability to scale up or down on demand. If you create less data when school is out of session, you’re not paying for empty storage servers to sit there and draw down power.

Workload Efficiencies. Rather than provisioning and maintaining on-premises hardware or managing a legacy tape backup system, moving infrastructure to the cloud frees up IT staff to focus on bigger priorities. All of the equipment is managed by the cloud provider.

Centralized Backup Management. Managing backups in-house across multiple campuses and systems for staff, faculty, and students can quickly become a huge burden, so many school districts opt for a backup software solution that’s integrated with cloud storage. The integration allows them to easily tier backups to object storage in the cloud. Veeam is one of the most common providers of backup and replication solutions. They provide a one-stop shop for managing backups—including reporting, monitoring, and capacity planning—freeing up district IT staff from hours of manual intervention.

Ransomware Protection. With schools being targeted more than ever, the ransomware protection provided by some public clouds couldn’t be more important. Tools like Object Lock allow you to recreate the “air gap” protection that tape provides, but it’s all in the cloud. With Object Lock enabled, no one can modify, delete, encrypt, or tamper with data for a specific amount of time. Any attempts by a hacker to compromise backups will fail in that time. Object Lock works with offerings like immutability from Veeam so schools can better protect backups from ransomware.

Considerations for Choosing a Cloud Provider for Your District

Moving to the cloud to manage backups or replace on-premises infrastructure can provide significant benefits for K-12 school districts, but administrators should carefully consider different providers before selecting one to trust with their data. Consider the following factors in an evaluation of any cloud provider:

1. Security: What are the provider’s ransomware protection capabilities? Does the provider include features like Object Lock to make data immutable? Only a few providers offer Object Lock, but it should be a requirement on any school district’s cloud checklist considering the rising threat of ransomware attacks on school districts. During 2020, the K-12 Cybersecurity Resource Center cataloged 408 publicly-disclosed school incidents versus 122 in 2018.
2. Compliance: Districts are subject to local, state, and federal laws including HIPAA, so it’s important to ensure a cloud storage provider will be able to comply with all pertinent rules and regulations. Can you easily set lifecycle rules to retain data for specific retention periods to comply with regulatory requirements? How does the provider handle encryption keys, and will that method meet regulations?
3. Ease of Use: Moving to the cloud means many staff who once kept all of your on-premises infrastructure up and running will instead be managing and provisioning infrastructure in the cloud. Will your IT team face a steep learning curve in implementing a new storage cloud? Test out the system to evaluate ease of use.
4. Pricing Transparency: With varying data retention requirements, transparent pricing tiers will help you budget more easily. Understand how the provider prices their service including fees for things like egress, required minimums, and other fine print. And seek backup providers that offer pricing sensitive to educational institutions’ needs. Veeam, for example, offers discounted public sector pricing allowing districts to achieve enterprise-level backup that fits within their budgets.
5. Integrations/Partner Network: One of the risks of moving to the cloud is vendor lock-in. Avoid getting stuck in one cloud ecosystem by researching the providers’ partner network and integrations. Does the provider already work with software you have in place? Will it be easy to change vendors should you need to?
6. Support: Does your team need access to support services? Understand if your provider offers support and if that support structure will fit your team’s needs.

As you research and evaluate potential cloud providers, create a checklist of the considerations that apply to you and make sure to clearly understand how the provider meets each requirement.

Preparing for a Cloud Migration at Your School District

Even when you know a cloud migration will benefit your district, moving your precious data from one place to another can be daunting at the least. Even figuring out how much data you have can be a challenge, let alone trying to shift a culture that’s accustomed to having hardware on-premises. Having a solid migration plan helps to ensure a successful transition. Before you move your infrastructure to the cloud, take the time to consider the following:

1. Conduct a thorough data inventory: Make a list of all applications with metadata including the size of the data sets, where they’re located, and any existing security protocols. Are there any data sets that can’t be moved? Will the data need to be moved in phases to avoid disruption? Understanding what and how much data you have to move will help you determine the best approach.
2. Consider a hybrid approach: Many school districts have already invested in on-premises systems, but still want to modernize their infrastructure. Implementing a hybrid model with some data on-premises and some in the cloud allows districts to take advantage of modern cloud infrastructure without totally abandoning systems they’ve customized and integrated.
3. Test a proof of concept with your new provider: Migrate a portion of your data while continuing to run legacy systems and test to compare latency, interoperability, and performance.
4. Plan for the transfer: Armed with your data inventory, work with your new provider to plan the transfer and determine how you’ll move the data. Does the provider have data transfer partners or offer a data migration service above a certain threshold? Make sure you take advantage of any offers to manage data transfer costs.
5. Execute the migration and verify results: Schedule the migration, configure your transfer solution appropriately, and run checks to ensure the data migration was successful.

How Cloud Storage Can Protect School District Data

Cloud-based solutions are integral to successful remote or hybrid learning environments. School districts have already made huge progress in moving to the cloud to enable remote learning. Now, they have the opportunity to capitalize on the benefits of cloud storage to modernize infrastructure as ransomware attacks become all the more prevalent. To summarize, here are a few things to remember when considering a cloud storage solution:

• Using cloud storage with Object Lock to store an off-site backup of your data means hackers can’t encrypt, modify, or delete backups within a set timeframe, and schools can more easily restore backups in the event of a disaster or ransomware attack.
• Increased ransomware protections allow districts to access the benefits of moving to the cloud like reduced CapEx, workflow efficiencies, and cost savings without sacrificing the security of air gapped backups.
• Evaluate a provider’s security offerings, compliance capability, ease of use, pricing tiers, partner network, and support structure before committing to a cloud migration.
• Take the time to plan your migration to ensure a successful transition.
