Summary

In this chapter, you have learned about or recapped the high-level design of large software projects, from traditional monolithic applications to microservices-based applications. You were also introduced to a brief history of microservices, the limitations of monolithic applications, and the benefits and flexibility that microservices offer. I hope this chapter helped you to understand the common problems faced in a production environment by monolithic applications and how microservices can resolve such problems. You were also introduced to lightweight and efficient Docker containers and saw how containerization is an excellent way to simplify microservices deployment.

In the next chapter, you will learn about setting up a development environment, looking at everything from your IDE and other development tools, to different libraries. We will deal with creating basic projects and setting up a Spring Boot configuration to build and develop our first microservice. We will be using Java 11 as the language and Spring Boot for our project.
