The microservices fad is hilarious. Let’s replace direct function calls and direct channels of communication with calls and channels over a network, and that will magically make our software more maintainable.

There is nothing a microservice does for maintainability that an interface and modularity won’t do.

It only makes sense if there are specific resource intensive things that need to scale separately, or if you have more than one language or runtime.

It’s probably something pushed by cloud providers to increase lock in and use more resources, since adding self hosting capability to a microservice based system that is dependent on Kubernetes is going to be that much harder.
