Do you have an auth service that does not do API? Does your API ask the auth rather than reaching into the auth table to see who is authorized? When you send an email, do you do it inline or do you trigger a push to a queue with separate worker(s)? Does your externally accessible API talk to internal services using a predefined protocol rather than reaching directly into a database?

Congratulations, you have micro services!

As someone who have driven the migration from a monolith (just set environment variables and magically the same codebase becomes auth, notifications, workers, web and API and the same codebase reaches into every single database and talks to every single service) into micro services because a simple features were taking months to implement, I can confidently say that even today, in 2022, an average organization does not have the tooling or the team to do a monolith. Monolith is a cargo cult. Break stuff into an digestable chunks, externalize your own internal libraries if they are shared, version the interfaces and stop worrying about microservice complexities.
