In this chapter, you learned about Spring Boot and its key features to build production-ready applications.

We explored the previous-generation web applications and then how Spring Boot makes developers' lives easier to develop fully qualified microservices. We also discussed the asynchronous message-based interaction between services. Further, we explored how to achieve some of the key capabilities required for microservices, such as security, HATEOAS, cross-origin, configurations, and so on with practical examples. We also took a look at how Spring Boot actuators help the operations teams and also how we can customize it to our needs. Finally, documenting microservices APIs was also explored.

In the next chapter, we will take a deeper look at some of the practical issues that may arise when implementing microservices. We will also discuss a capability model that essentially helps organizations when dealing with large microservices implementations.
