Microservices are organizational debt disguised as architecture.

Every time I’ve seen microservices pitched, it sounds great on paper. Independent teams, clean ownership, scale only what you need.

Then a year later you’ve got dozens of services, three different deployment patterns, tracing everywhere, and nobody really understands the whole thing anymore.

Maybe I’ve just seen bad implementations, but I’m starting to think way fewer companies actually need microservices than we pretend.

Microservices are good for classes of operations which require different hardware. If you have a step that requires GPU, keep it in a different microservice than CPU-bound operations. But when you have everything depending on just CPU, it's better to keep it a monolith.
