Sounds like a great way to get locked into paying for more than you need.

There's a venerable history of this, from Oracle to Heroku. Solve today's problems slightly faster (minus a few days of plateng/DevOps work), and forever be exposed to having the screws tightened.

Hard pass. Infra should be commodity and replete with dozens of like kinded alternatives.

The worst offenders are those fancy JS CI/CD, one-click deploy solutions that cost 10,000x the underlying primitives. Roll your own and save yourself.
