Summary

In this chapter, we converted the modular monolith application into a microservices application. We modified the modules in such a way that we could continue to run the application as a monolith or with microservices. This is not exactly a goal most teams have but we could do it, so we did. A real application would likely begin to diverge and maybe pick up new microservices that are written in different languages, which would make keeping the monolith around an unlikely outcome.

We also set up our environment to deploy our application into the cloud using either a containerized approach or installing the necessary tools directly onto our system. We used these tools to stand up the infrastructure that our application needed to be run on top of first. Then, as a second step, we deployed the application itself to AWS. The experiences between the locally running application as a monolith, as microservices, and as a cloud deployment remained exactly the same.
