Again, you don’t understand them, so you think they’re too complicated, so you’re scared of them.

You illustrate your lack of knowledge. First, with the right knowledge and tools, it's not at all that complicated. IaC is a real thing. I can define all my needed infrastructure in less than 1000 lines of code. I taught this to a Junior developer straight out of coding boot camp; she used to be a nurse. If she can pick it up in 2 months, it's not that complicated. The boot camp took longer than it did for her to understand how to deploy applications in the cloud on both serverless and tenanted systems.

Second you have zero perspective, complicated is NOT the issue. Reliability is the issue.

I can guarantee you that my multi-region, multi-AZ deployed serverless and tented services are 1000x more reliable and responsive under load than the few boxes you have in a data center or under your desk. They are also 100% backed up continuously and will recover so fast from even catastrophic crashes that end users typically only experience a blip (if they even notice at all) as the load balancer shifts them to another endpoint.

In addition, it takes me mere minutes to spin up new servers for development and testing or to handle additional load.
