You’re entitled to your opinion, but I want to point out that learning N different custom infra as code systems for N clouds is not really sustainable. If you’re mostly using just one cloud, it makes more sense. Terraform is cloud agnostic in that once you build a process around it… CI/CD of Infra as Code, runbooks around how to work with failures, break glass etc, you can basically use the same thing for any cloud, since all of them have terraform “providers”.

Also all the major clouds (even the minor ones) have pretty strong first class support for terraform.
