Complexity in Microservices
As you add microservices to your stack, the number of connections follows Metcalfe’s law. In the simplest case, there’s just a single connection between two services. As you reach five services, connections can happen in 10 different ways. A stack with twenty services has 190 possible connections. The complexity of managing, supporting, and understanding those connections is something you should consider as your stack grows.
