Very few companies reach the scale such that they require microservices. It’s not even about raw scale either as monoliths can also scale. Microservices serve only a specific kind of scale. Think about it. Load balancing across multiple servers? You can scale that monolith.

Most companies that switch to microservices often do it because of hype. The most common excuse is that microservices prevent spaghetti code as if carving it into different services is the thing that creates modularity while forgetting that folders and functions do the same exact thing.

It’s generally weak reasoning. Better to go with reasoning that is logically invariant like what I brought up in this thread.
