Working with Microservices

After reading the previous two chapters, you should now have an understanding of the Docker architecture and its concepts. Before we go further on our Java, Docker, and Kubernetes journey, let's get to know the concept of microservices.

By reading this chapter, you will find out why a transition to microservices and cloud development is necessary and why monolithic architecture is not an option anymore. The microservices architecture is also where Docker and Kubernetes will be especially useful.

This chapter will cover the following topics:

• An introduction to microservices and comparison to a monolithic architecture
• How Docker and Kubernetes fits into the microservices world
• When to use microservices architecture

Before we actually create the Java microservice and deploy it using Docker and Kubernetes, let's start with an explanation of the microservices idea and compare it to the monolithic architecture.
