This chapter was intended to give you an overview of what you can expect from reading this book.
We have recalled basic information about Java EE and the traditional way in which it was used to develop enterprise application. Later, we introduced modern trends in software development: cloud computing and microservices architecture.
Then, we introduced the pet store—the sample application that we are going to develop throughout the book.
Finally, we introduced all the technologies and tools used throughout the book, such as WildFly Swarm, OpenShift, Hystrix, Jenkins, and Keycloak.
