I tried to understand what is it, how it works, what is it good for, but ... never managed to. It still has the same "build control planes without needing to write code" on its website. okay, it says "orchestrate applications and infrastructure". that's at least makes sense when the context is Terraform and Pulumi.
okay, in the quickstart the whole thing seems like code. but okay.
ah, so you can use k8s CRDs to define cloud stuff (like S3 buckets and GCP GCS buckets and whatnot), not bad, but super verbose.
