Serverless Java

Serverless, also known as function as a service (FaaS), is one of the hottest trends these days. It is an application/deployment model where a small function is deployed to a service that manages almost every aspect of the function--startup, shutdown, memory, and so on, freeing the developer from worrying about such details. In this chapter, we'll write a simple serverless Java application to see how it might be done, and how you might use this new technique for your own applications.

This project will cover the following:

• Creating an Amazon Web Services account
• Configuring AWS Lambda, Simple Notification Service, Simple Email Service, and DynamoDB
• Writing and deploying a Java function
