Overview of this book

Java is a powerful language that has applications in a wide variety of fields. From playing games on your computer to performing banking transactions, Java is at the heart of everything. The book starts by unveiling the new features of Java 9 and quickly walks you through the building blocks that form the basis of writing applications. There are 10 comprehensive projects in the book that will showcase the various features of Java 9. You will learn to build an email filter that separates spam messages from all your inboxes, a social media aggregator app that will help you efficiently track various feeds, and a microservice for a client/server note application, to name a few. The book covers various libraries and frameworks in these projects, and also introduces a few more frameworks that complement and extend the Java SDK. Through the course of building applications, this book will not only help you get to grips with the various features of Java 9, but will also teach you how to design and prototype professional-grade applications with performance and security considerations.

Chapter 10. Serverless Java

In recent years, the concept of microservices, which we've already looked at, has swept across the industry, quickly displacing the battle-tested application server with something smaller and leaner. Right on the heels of microservices comes a new concept--Functions as a Service, more commonly called serverless. In this chapter, you'll learn more about this new deployment model and build an application to demonstrate how to use it.

The application will be a simple notification system using the following technologies:

  • Amazon Web Services
    • Amazon Lambda
    • Amazon Identity and Access Management (IAM)
    • Amazon Simple Notification System (SNS)
    • Amazon Simple Email System (SES)
    • Amazon DynamoDB
  • JavaFX
  • The options offered by cloud providers can be quite vast, and Amazon Web Services is no exception. In this chapter, we will attempt to use just enough of what AWS has to offer to help us build a compelling application as we wade into cloud-native application development.
