I just don't see this. Building what I am describing can be done in days sometimes hours. Where exactly is the time and complexity? I would be willing to bet given a true greenfield(e.g. I can't use an ansible script that stole from my last job) I can build an autoscaling flask app with CI/CD and local environment on ECS twice as fast as accomplishing a lesser facsimile with a bare metal server or a VPS. If I built on a VPS I would still have concerns like backups, High Availability, DNS, Networking, etc. etc. to deal with.

I consider the latter to be far more complex.
