This chapter started with explaining why you need Apache Ignite and how adding a new tool to your tech toolbox can help you solve different problems. We looked at the rich features of Apache Ignite, explored Apache Ignite use cases, and refactored traditional architecture building blocks using Apache Ignite support.
We then installed Apache Ignite on Windows and Mac, created a Hello World program to access an Ignite cache, and finally compared Apache Ignite with other frameworks.
In Chapter 2, Understanding the Topologies and Caching Strategies, we will explore caching strategies and Ignite clustering.
