Let's recap what we have done so far. We started by looking at the advantages of building applications based on microservices. Then, we looked at several tools that can help us start building our microservices. We stood with Express and embarked on building a simple microservice.
We learned the basics of state and security by interconnecting our microservice and a database server. We've chosen a test suite and added tests until we had a very good code coverage.
Finally, we learned how to deploy our microservice using containers. We then explored how we could scale our microservice using replicas across different sites.
When we deploy our microservice inside a container, we're opening a new world of possibilities. ...
