Summary

In this chapter, we learned about the need to have a cloud environment when dealing with internet-scale microservices.

We explored the concept of containers and compared them with traditional virtual machines. We also learned the basics of Docker and were explained the concepts of Docker images, containers, and registry. The importance and benefits of containers were explained in the context of microservices.

This chapter then switched to a hands-on example by Dockerizing the BrownField microservices. We demonstrated how to deploy the Spring Boot microservices developed earlier on Docker. We learned the concept of registry by exploring a local registry, as well as the Docker Hub for pushing and pulling Dockerized microservices.

As a last step, we explored how to deploy Dockerized BrownField microservices in the AWS cloud environment.
