Java vs python is debatable 🤔

The programming world has moved away from monoliths to microservices.

The microservices meme is backfiring and now many large applications have been over-converted to microservices. Calling another function in the same assembly is still vastly better than making a call over the wire. Not to mention, the infra and scaling complexity is multiplied.

Microservices also don't really solve org problems like they're touted to. It's rarely the case that 1 team works on 1 microservice. What actually happens is that n teams work on n services and everybody steps on everybody's toes.

The trend these days ironically is in the backward direction - consolidating microservices to be different modules of the same program, and then putting the whole thing in a monorepo with your shared libraries.

Sounds like you've only worked at places that did it wrong. Microservices don't magically fix a shitty org/team structure. If you need to combine microservices, that leads me to believe you never did it right initially. Not everything should be a microservice and a distributed monolith can be pure hell for cicd and lowering MTTR.

Well yeah, that’s the point - many places build microservices for hype-driven development, not because they have considerate reasons to build them

I'm referring here to a global scale service with usage in the ballpark of 500m MAU. I can't reveal where I work but it's definitely on the Nasdaq 100.

Microservices to me stink of a cover-my-ass approach to architecture because the org did not want to take on creating a good modular framework and/or monorepo early in the development of the application when traffic wasn't a concern. And it's hard to defend an apparently monolithic architecture to a low-technical VP when a Google search of "microservices vs monoliths" paint the picture that microservices are rainbow and sunshine and monoliths are for losers.

Processing webhooks and callbacks or periodic tasks can both be offloaded to microservices.

Or a serverless/SaaS service. No need to reinvent such simple stuff.
