The aws examples take me back to when I worked for a business where all technical decisions in a LoB were made by the non technical LoB manager.
A particular LoB had ignored our warnings that their technology selection would not scale, implemented a website that was incapable of scaling, paid the developer of the tech for a cluster license (5000 bucks per quarter per server I was told) and implemented the technology in such a way that they could not identify when 1 member of the cluster had failed to automate fail over.
Instead of fixing it (a months development time to port to another web platform max), they simply planned to have a tech online for their high traffic events to manually pull cluster members that stopped responding out of the cluster, reboot them, then add them back into the pool for 3 hours straight.
Then they would throw more resources at the VM, and grunt about the infrastructure team not doing their jobs. It was insane. This platform would quit responding at What was extra fun was when they paid a very large AWS integrator to move the cluster to the cloud. When the AWS integrator got a look at it they just walked away. So instead they paid a local mob to do it.
At the time, pulling a windows environment up and down via cloud formation was not something that automated easily. They got 50% of the way through and realised oh shit, this is either going to cost us 10x the contract value or might even be impossible, so that local group ghosted them taking 100% of contract funds (I got to be in the meeting where they actually read the contract, and they had a very good contract that no one had read that allowed them to declare a technical impasse and bail with all paid monies. OFC they paid 100% in advance) too. So they ate the spend, and just called AWS the "DEV" environment, deleted the cloud formation scripts, and started packaging deployments back to "Prod" which was running on the infrastructure they would never stop hating on.
Once that was done they called an all staff meeting to praise the team for completing their project only 3 years late.
