In the previous chapters, you learned how to build a Microservice application with the Go programming language and how to (continuously) deploy it into various environments.
However, our work is not yet complete. When you have an application running in a production environment, you will need to ensure that it stays up and running and behaves the way that you as a developer intended. This is what monitoring is for.
