Summary
You should now have a feel for the cloud-native example that will be used throughout this book. Though it may appear a bit daunting at first, the mandatory parts are quite easy to set up (especially if you use the pre-built images in Docker Hub), so you can be up and running with the basics of the example in a matter of minutes. Then, you can add whichever of the optional bonus capabilities you'd like at your own pace.
In the upcoming chapters, various MicroProfile technologies will be discussed in detail. Each will show snippets from particular microservices in this example. As you have seen, different microservices are meant to demonstrate different features of Jakarta EE and MicroProfile and provide a real running tutorial of how to integrate with various external services.
In Chapter 8, Building and Testing your Cloud-Native Application we'll examine how these microservices were developed so that you can learn how to develop such microservices yourself....
