You think cloud is too expensive or unnecessary? Fair enough, this tool is not for you.
You think cloud infra is necessarily complex because you need to support <insert use case here>. You're right! This tool is not for you (yet?).
You don't need this because you already know <CDK / Terraform / whatever abstraction is already in your repertoire>? I agree, the juice is probably not worth the squeeze to learn yet another tool.
Are you approaching cloud for the first time or have been managing existing simple infra (buckets, queues, lambdas) via ClickOps and want to explore a feature constrained (hence easy to grok) Infrastructure as Code solution? Maybe give this a look.
While it's still early days, I suspect there will be many who will find this useful, and congratulate the authors for their efforts!
