Summary

In this chapter, you 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. You also learned the basics of Docker, and we explained the concepts of Docker images, containers, and registries. 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 microservice. We demonstrated how to deploy the Spring Boot microservice developed earlier on Docker. You learned the concept of registries by exploring a local registry as well as the Docker Hub to push and pull dockerized microservices.

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