strangler-fig

Repository for the workshop on the "Money Problem"

Everyday is getting more and more popular and, sometimes, worthy and useful -> split a monolith into microservices. In this repo I will show an example of how to split a monolith into microservices using the Strangler Fig and Branch By Abstraction patterns.
