ICYMI: Serverless Q3 2020

Post Syndicated from James Beswick original https://aws.amazon.com/blogs/compute/icymi-serverless-q3-2020/

Welcome to the 11th edition of the AWS Serverless ICYMI (in case you missed it) quarterly recap. Every quarter, we share all of the most recent product launches, feature enhancements, blog posts, webinars, Twitch live streams, and other interesting things that you might have missed!

In case you missed our last ICYMI, checkout what happened last quarter here.

AWS Lambda

MSK trigger in Lambda

In August, we launched support for using Amazon Managed Streaming for Apache Kafka (Amazon MSK) as an event source for Lambda functions. Lambda has existing support for processing streams from Kinesis and DynamoDB. Now you can process data streams from Amazon MSK and easily integrate with downstream serverless workflows. This integration allows you to process batches of records, one per partition at a time, and scale concurrency by increasing the number of partitions in a topic.

We also announced support for Java 8 (Corretto) in Lambda, and you can now use Amazon Linux 2 for custom runtimes. Amazon Linux 2 is the latest generation of Amazon Linux and provides an application environment with access to the latest innovations in the Linux ecosystem.

Amazon API Gateway

API integrations

API Gateway continued to launch new features for HTTP APIs, including new integrations for five AWS services. HTTP APIs can now route requests to AWS AppConfig, Amazon EventBridge, Amazon Kinesis Data Streams, Amazon SQS, and AWS Step Functions. This makes it easy to create webhooks for business logic hosted in these services. The service also expanded the authorization capabilities, adding Lambda and IAM authorizers, and enabled wildcards in custom domain names. Over time, we will continue to improve and migrate features from REST APIs to HTTP APIs.

In September, we launched mutual TLS for both regional REST APIs and HTTP APIs. This is a new method for client-to-server authentication to enhance the security of your API. It can protect your data from exploits such as client spoofing or man-in-the-middle. This enforces two-way TLS (or mTLS) which enables certificate-based authentication both ways from client-to-server and server-to-client.

Enhanced observability variables now make it easier to troubleshoot each phase of an API request. Each phase from AWS WAF through to integration adds latency to a request, returns a status code, or raises an error. Developers can use these variables to identify the cause of latency within the API request. You can configure these variables in AWS SAM templates – see the demo application to see how you can use these variables in your own application.

AWS Step Functions

X-Ray tracing in Step Functions

We added X-Ray tracing support for Step Functions workflows, giving you full visibility across state machine executions, making it easier to analyze and debug distributed applications. Using the service map view, you can visually identify errors in resources and view error rates across workflow executions. You can then drill into the root cause of an error. You can enable X-Ray in existing workflows by a single-click in the console. Additionally, you can now also visualize Step Functions workflows directly in the Lambda console. To see this new feature, open the Step Functions state machines page in the Lambda console.

Step Functions also increased the payload size to 256 KB and added support for string manipulation, new comparison operators, and improved output processing. These updates were made to the Amazon States Languages (ASL), which is a JSON-based language for defining state machines. The new operators include comparison operators, detecting the existence of a field, wildcarding, and comparing two input fields.

AWS Serverless Application Model (AWS SAM)

AWS SAM goes GA

AWS SAM is an open source framework for building serverless applications that converts a shorthand syntax into CloudFormation resources.

In July, the AWS SAM CLI became generally available (GA). This tool operates on SAM templates and provides developers with local tooling for building serverless applications. The AWS SAM CLI offers a rich set of tools that enable developers to build serverless applications quickly.

AWS X-Ray

X-Ray Insights

X-Ray launched a public preview of X-Ray Insights, which can help produce actionable insights for anomalies within your applications. Designed to make it easier to analyze and debug distributed applications, it can proactively identify issues caused by increases in faults. Using the incident timeline, you can visualize when the issue started and how it developed. The service identifies a probable root cause along with any anomalous services. There is no additional instrumentation needed to use X-Ray Insights – you can enable this feature within X-Ray Groups.

Amazon Kinesis

In July, Kinesis announced support for data delivery to generic HTTP endpoints, and service providers like Datadog, New Relic, MongoDB, and Splunk. Use the Amazon Kinesis console to configure your data producers to send data to Amazon Kinesis Data Firehose and specify one of these new delivery targets. Additionally, Amazon Kinesis Data Firehose is now available in the Europe (Milan) and Africa (Cape Town) AWS Regions.

Serverless Posts

Our team is always working to build and write content to help our customers better understand all our serverless offerings. Here is a list of the latest posts published to the AWS Compute Blog this quarter.

Tech Talks & Events

We hold several AWS Online Tech Talks covering serverless tech talks throughout the year, so look out for them in the Serverless section of the AWS Online Tech Talks page. We also regularly deliver talks at conferences and events around the globe, regularly join in on podcasts, and record short videos you can find to learn in quick byte sized chunks.

Here are some from Q3:

Learning Paths

Ask Around Me

Learn How to Build and Deploy a Web App Backend that Supports Authentication, Geohashing, and Real-Time Messaging

Ask Around Me is an example web app that shows how to build authenticaton, geohashing and real-time messaging into your serverless applications. This learning path includes videos and learning resources to help walk you through the application.

Build a Serverless Web App for a Theme Park

This five-video learning path walks you through the Innovator Island workshop, and provides learning resources for building realtime serverless web applications.

There are also a number of other helpful video series covering serverless available on the Serverless Land YouTube channel.

New AWS Serverless Heroes

Serverless Heroes Q3 2020

We’re pleased to welcome Angela Timofte, Luca Bianchi, Matthieu Napoli, Peter Hanssens, Sheen Brisals, and Tom McLaughlin to the growing list of AWS Serverless Heroes.

The AWS Hero program is a selection of worldwide experts that have been recognized for their positive impact within the community. They share helpful knowledge and organize events and user groups. They’re also contributors to numerous open-source projects in and around serverless technologies.

New! The Serverless Land website

Serverless Land

To help developers find serverless learning resources, we have curated a list of serverless blogs, videos, events and training programs at a new site, Serverless Land. This is regularly updated with new information – you can subscribe to the RSS feed for automatic updates, follow the LinkedIn page or subscribe to the YouTube channel.

Still looking for more?

The Serverless landing page has lots of information. The Lambda resources page contains case studies, webinars, whitepapers, customer stories, reference architectures, and even more Getting Started tutorials.
