Microservices are popular because managing large teams is a pain in the ass and creating a small team to spin off some new business case is really easy to manage. You get budget, you create the new team, if it sucks, reorganize or fire the team (and offload the services to other teams). I'm telling you, it's all Conway's Law. We literally just don't want to think about the design in a complex way, so we make tiny little apps and then hand-wave the complexity away. I've watched software architects get red in the face when you ask them how they're managing dependencies and testing for 100s of interdependent services changing all the time, because they literally don't want to stop and figure it out. Microservices are just a giant cop-out so somebody can push some shit into production without thinking of the 80% maintenance cost.
