Look inside
In this liveProject, you’ll prepare an old monolithic application for migration to microservices by converting it to be a REST-based service. You’ll break up an established monolith by using bounded contexts to give your microservices responsibility over a smaller part of the business domain. You’ll convert these microservices to use RESTful APIs, allowing for the existing business logic to remain intact, and leaving behind a static Thymeleaf-based user interface allows another team to write a modern front end.
This project is designed for learning purposes and is not a complete, production-ready application or solution.
