Oh, it is even worse.

The MAIN reason for microservices was that you could have multiple teams work on their services independently from each other. Because coordinating work of multiple teams on a single huge monolithic application is a very complex problem and has a lot of overhead.

But, in many companies the development of microservices/agile teams is actually synchronised between multiple teams. They would typically have common release schedule, want to deliver larger features across multitude of services all at the same time, etc.

Effectively making the task way more complex than it would be with a monolithic application

I've worked with thousands of other employees on a single monolithic codebase, which was delivered continuously. There was no complex overhead.

The process went something like this:

1. write code

2. get code review from my team (and/or the team whose code I was touching)

3. address feedback

4. on sign-off, merge and release code to production

5. monitor logs/alerts for increase in errors

In reality, even with thousands of developers, you don't have thousands of merges per day, it was more like 30-50 PRs being merged per day and on a multi-million line codebase, most PR's were never anywhere near each other.

Regarding monoliths...when there's an issue, now everyone who made a PR is subject to forensics to try to identify cause. I rather make a separate app that is infrequently changed, resulting in less faults and shorter investigations. Being on the hook to try to figure out when someone breaks "related" to my team's code, is also a waste of developer time. There is a middle ground for optimizing developer time, but putting everything in the same app is absurd, regardless of how much money it makes.

50 PRs with a thousand developers is definitely not healthy situation.

It means any developer merges their work very, very rarely (20 days = 4 weeks on average...) and that in my experience means either low productivity (they just produce little) or huge PRs that have lots of conflicts and are PITA to review.
