Microservices probably do increase the overall amount of complexity in a sense, but the idea is to trade a little bit of complexity in order to decouple teams. i.e., each team can own its service from soup to nuts without having to coordinate with a bunch of other teams. To put it differently, there’s a small increase in technical complexity in exchange for a significant decrease in organizational complexity. That said, if you go out of your way to retain that organizational complexity (e.g., by dividing your services in a way that doesn’t resemble your org chart) then you’re going to have a bad time with microservices. Similarly, if you don’t have organizational complexity (e.g., you only have one or two teams) then microservices are probably the wrong way to go.
