What are the modern equivalents? For Terraform I'd imagine it's Pulumi or OpenTofu but what is it for Vault? Last I checked OpenBao didn't seem to have much juice but it's been a minute since I did so. Or are there unrelated projects in this space that are on the same trajectory as Hashicorp was a decade ago?
Crossplane is excellent but you need to understand CRDs and kubectl at what I'd consider n intermediate level to really grok it whereas Terraform's CLI is almost fool-proof.
Relying on cloud key vaults is expensive and locks you in. Vault and Consul can run anywhere, even in your toaster. They also support those same KMS. Also, dead easy TUI and GUI with Vault Enterprise
