I just checked, pulumi does have a good track record of keeping up with AWS. But using a non industry standard framework (Stevio) just doesn’t make any sense from a long term portable career perspective.

While I’m not a fanatic about which one I use out of the major ones. My last three projects were CDK/Typescript, Terraform and CloudFormation with my own collection of utility scripts I’ve used over 5 years to make it act more like TF. But the CFTs are standard.
