I've seen an application, a 95% CRUD application, which had about 100-1000 users across the UK, users who would only be using it from 9am-5:30pm, and at that - barely interacting with it. This was backed by literally the most sophisticated and complex architecture I have ever seen in my entire life.

There were 3 instances of cognito. RDS, DynamoDB and S3. The entire architecture diagram would only be legible on an A2 (heck, maybe even A1) page. And that was the high level diagram. The central A4 part of that diagram was a bunch of micro-services for handling different portions of this CRUD application.

This company could afford a system architect as well as a team of developers to work on this full time.

I was genuinely baffled, but this company was in an extremely lucrative industry, so I guess in this case it's fine to just take some of your profits and burn them.
