that’s a loaded statement without understanding the company.

Sometimes large companies acquire smaller companies and keep the lights on in the old system for a while. They may not even use a similar tech stack!

Sometimes they want to cleanly incorporate the acquired systems into the existing architecture but that might take years of development time.

Sometimes having a distributed system can be beneficial. Pros / cons.

and sometimes it’s just a big company with many people working in parallel, where it’s hard to deploy everything as a single web app in a single pipeline.
