Refactoring a monolith to Microservices.

Microservices are all the hype off late. They promise separation of business functions into units that can be developed, deployed and managed independently of other services, and are maintained by a single team.

All of that sounds nice, but how do you get there? How do you go about transforming a dinosaur into a herd of gazelles?

We have been carving up a digital dinosaur to see what challenges we run into, like choosing service boundaries, communication between services, and refactoring code.

To participate you’ll need a laptop with Java and Maven installed. IntelliJ will probably make your life easier. We’ll be using Spring Boot and provide a repository on GitHub.
