Java EE 8 High Performance

By: Romain Manni-Bucau

Overview of this book

The ease with which we write applications has been increasing, but with this comes the need to address their performance. A balancing act between easily implementing complex applications and keeping their performance optimal is a present-day need. In this book, we explore how to achieve this crucial balance while developing and deploying applications with Java EE 8. The book starts by analyzing various Java EE specifications to identify those potentially affecting performance adversely. Then, we move on to monitoring techniques that enable us to identify performance bottlenecks and optimize performance metrics. Next, we look at techniques that help us achieve high performance: memory optimization, concurrency, multi-threading, scaling, and caching. We also look at fault tolerance solutions and the importance of logging. Lastly, you will learn to benchmark your application and also implement solutions for continuous performance evaluation. By the end of the book, you will have gained insights into various techniques and solutions that will help create high-performance applications in the Java EE 8 environment.

Money – The Quote Manager Application

Before working on evaluating and enhancing the performance of your application, you need to indeed have an application. In this part, we will create a small application that we will use to illustrate every part of the book. This chapter doesn't intend to explain all the steps required to create a Java EE application. It will give you the overall steps and ensure that the references to the steps will be obvious later.

The use case of this application will be a microservice that provides a set of web services to manage stocks and shares. This chapter will, therefore, introduce you to the application environment:

  • Application code structure
  • Database setup
  • Data persistence
  • Exposing data over HTTP
  • Deploying your application
