More Hands-on Microservices

You coded your first and simplest microservice in the last chapter. That example used a simple data structure as an in-memory database. This chapter extends that example by creating a few more microservices, each one in increasing order of complexity. This will enable you to build on your prior learnings. You will interact with a few real databases and firm up your knowledge of the ports and adapters architecture introduced in Chapter 1 .
