TECH SPOTLIGHT: SERVERLESS AND JAVA
This week the spotlight is on serverless for Java. Specifically, we want to focus on the technologies in the JVM ecosystem that make going serverless with Java and AWS Lambda possible. Often when we think about serverless, we default to dynamic languages like Node.js or Python, but the JVM ecosystem is robust, time tested, and well supported by the enterprise and open source communities.
But what about cold-starts? It’s well known that AWS Lambda cold-starts for Java tend to be slower than Node.js and Python. To solve this, we have released updates to AWS Lambda and the AWS SDK for Java that drastically improve the cold start of your application's Java functions. At AWS re:Invent 2019, Stefano Buliani gave one of the highest rated talks about Best Practices for AWS Lambda and Java.
Even more recently, we’ve release Provisioned Concurrency, which enables a function to scale without fluctuations in latency. If Provisioned Concurrency doesn’t fit your specific project, there are many other optimizations you can make to significantly decrease cold start times, such as loading classes during initialization or avoiding reflection.
Several open source projects also are targeting the cold-start issue in serverless and container development, primarily Quarkus and Micronaut. Both of these projects are full-stack frameworks for building modern Java applications, optimized for native compilation. Don't worry, Spring developers, both of the frameworks are compatible with most of the Spring annotations: Quarkus for Spring, Micronaut for Spring.

Supercharging Your ECS Applications with the AWS CDK on July 30, 2020
In this tech talk, using AWS CDK, we will build and deploy our containers to ECS with three of the high-level ecs patterns available today. The patterns we'll demo will be: deploying an application load balanced Fargate service, an SQS queue consumer service, as well as a time based scheduled task that runs on an interval. Register here.
AWS Container Day on August 17, 2020
Tune in for a full-day of virtual sessions covering how Amazon EKS makes it easy to deploy, manage, and scale containerized applications using Kubernetes. There will be technical deep dives, product demos, and product announcements, and the AWS Kubernetes team will be streaming on Twitch all day, ready to answer your questions.

GUIDES AND TUTORIALS
Deploy a Kubernetes application (30 minutes)
This tutorial shares how Amazon EKS can deploy a highly available Kubernetes control plane, and configure 'kubectl', an open source command-line tool to interact with your Kubernetes infrastructure. We recommend this tutorial for anyone who wants to quickly try running Kubernetes on AWS. Get started
Schedule a serverless workflow (10 minutes)
This quick tutorial shows how to use serverless workflow to automate patch management, ETL jobs, data synchronization, or security. You will be using AWS Step Functions to orchestrate a serverless workflow in response to an Amazon CloudWatch event. Get started
Send messages between distributed applications (10 minutes)
This tutorial explains how to create and configure a message queue, send a message, receive and delete that message, and then delete the queue. You will be setting up asynchronous messaging with Amazon Simple Queue Service (Amazon SQS). Get started
Build and deploy a full stack serverless React App using AWS Amplify (50 minutes)
This tutorial will create a simple web application using AWS Amplify, an open source framework and static web hosting service to accelerate building and deploying web apps with AWS. Get started
PRODUCT LAUNCHES AND RELEASE NOTES
Introducing the Cloud Development Kit (CDK) for Kubernetes
We recently announced the Alpha release of Cloud Development Kit for Kubernetes (cdk8s). cdk8s is an open source software development framework for defining Kubernetes applications using general-purpose programming languages. Read more
Announcing CDK Pipelines Preview, continuous delivery for AWS CDK applications
In addition to Cloud Development Kit (CDK) for Kubernetes, CDK has announced a feature called CDK Pipelines that makes it easy to set up simple or complex continuous delivery pipelines with AWS CodePipeline. CDK Pipelines gets your continuous pipeline started quickly by automatically creating several predefined stages and actions, and makes it easy to add more stages and actions to suit your needs. The pipeline created by CDK Pipelines is self-mutating. This means you only need to deploy the pipeline once to get it started and, after that, the pipeline automatically updates itself when you add new CDK applications or stages in the source code.
