Amazon Web Services announced that cloud developers can now use Java for writing Lambda functions, which provide event-driven functionality while taking care of needed compute resources.

At the recent re:Invent, AWS announced an update to its FaaS offering Lambda with SnapStart feature that reduces the cold start for Java Functions.

The first half of this article presented an overview of serverless computing with AWS Lambda, including building, deploying, and testing AWS Lambda functions in an example Java application.

To build AWS Lambda functions with Java, you can either consider Java programmers for hire or check out a comprehensive tutorial by AWS on how to invoke AWS Lambda functions from Java.

AWS unveils a new performance optimization feature called Lambda SnapStart, designed to improve startup times for latency-sensitive applications, and initially aimed at Java developers.

Don't be intimidated by the prospect of doing functional programming in Java. This step-by-step example will help you learn basic Java lambda syntax quickly and effectively.

Finally, you built a Lambda function in Java, then deployed the function to AWS Lambda and tested it in the AWS Lambda console. In Part 2, we’ll add support for Amazon’s DynamoDB.
