In this chapter, we learned how to use Eclipse with the AWS Toolkit plugin, and we used Java to create and test different Lambda functions. First, we created and tested a Lambda function with a simple string input/output, then a Lambda function that is triggered through S3 events, and, finally, a serverless project that consists of two Lambda functions that write to or read from DynamoDB and S3, respectively. In the next chapter, we are going to take a look how to program AWS Lambda using Python.

Overview of this book
AWS Lambda is a part of AWS that lets you run your code without provisioning or managing servers. This enables you to deploy applications and backend services that operate with no upfront cost. This book gets you up to speed on how to build scalable systems and deploy serverless applications with AWS Lambda.
The book starts with the fundamental concepts of AWS Lambda, and then teaches you how to combine your applications with other AWS services, such as AmazonAPI Gateway and DynamoDB. This book will also give a quick walk through on how to use the Serverless Framework to build larger applications that can structure code or autogenerate boilerplate code that can be used to get started quickly for increased productivity.
Toward the end of the book, you will learn how to write, run, and test Lambda functions using Node.js, Java, Python, and C#.
