The Importance of a CDN: Speed and Security

Post Syndicated from Sarah Wilson original https://www.anchor.com.au/blog/2017/03/importance-cdn-website-speed-security/

As a hosting provider, we speak with many businesses who need a fix for their slow site speeds. There are many contributing factors why hosting infrastructure may be constraining your site performance but typically; old infrastructure used by some hosting providers, contention issues and even the physical location of the servers.  Having your site hosted in a high-speed environment with world class managed services (such as Anchor) provides the right foundations and utilising a Content Delivery Network (CDN) that can give you that extra boost in speed and performance you desire – and deserve. One of the more popular site performance applications is Cloudflare; global network designed to optimize security, performance and reliability, without the bloat of legacy technologies. Cloudflare  has some robust CDN capabilities in addition to other security services like DDoS (Distributed Denial of Service) protection and reverse proxies.

A traditional CDN is a group of web servers distributed across multiple locations around the world, which delivers content more efficiently to users. The server selected for delivering content to a specific user is typically based on a measure of network proximity. For example, the server with the fewest network hops or the server with the quickest response time is chosen.

If you are looking to take advantage of a CDN,  a great place to to start is Cloudflare’s free plan. This basic plan can be set up in less than 5 minutes and only requires a simple change to your domain’s DNS settings to get you up and running. There is no hardware or software to install or maintain and you do not need to change any of your site’s existing code. As a partner of Cloudflare, we can offer discounted pricing to our customers if you are looking to take advantage of some of Cloudflare’s advanced performance and security features such as image optimisations, firewalls and PCI compliance to name just a few.

CloudFlare utilises more than 40 data centres in almost as many countries, and use the size of their ‘quietly built cloud’ to process more than 5% of all web requests. It includes:

  • A Global CDN
  • DDoS Protection
  • Page Rules

DDoS Protection- Why do I need it and how to protect against attack?

In 2015 the internet saw the highest rate of DDoS attacks ever. Generally, the attackers will flood a network or service (usually with thousands of IP addresses) in order to overwhelm the server and make a network or website unavailable for its users. It is extremely important to make sure your site is protected from such an attack, especially if your site is eCommerce and down time will prevent customers completing their purchases.

What are Global CDN’s?

As mentioned above, Content Delivery Networks (CDNs) are important for a number of reasons. The primary feature that a CDN does, is provides alternative server nodes, or locations for the user to download resources (usually JavaScript or static content). This means that although the server may be located in the US, someone in Sydney can still experience fast load speed and response times due to this reduced latency.  This is extremely important for sites that have users in other countries, especially those who are shopping online, as these sites generally have a large volumes of images, which can be timely to load. Overall, it improves your user’s experience in terms of speed.

Page Rules

Page Rules give you the ability to control how Cloudflare actually works on a URL or subdomain basis, which means it allows you to customise it’s functionality to match your domain’s unique needs. They give you the ability to take various actions based on the page’s URL, such as creating redirects, fine tuning caching behavior, or enabling and disabling our various services. This helps you to optimize speed, harden security, increase reliability, maximize bandwidth savings, and much more.

Other benefits include, the added scalability or capacity effects that a CDN like Cloudflare has, not only does it have higher availability but also lower packet loss. Further, Cloudflare provides website traffic insight and other analytics such as threat monitoring, so that you can improve your site even further.

As a partner of Cloudflare, Anchor receives discounted rates for the Pro and Business plans, as well as can help you install the free plan if you are a customer.  The easiest part about Cloudflare however, is that it only requires a simple change to your domain’s DNS settings. There is no hardware or software to install or maintain and you do not need to change any of your site’s existing code.
