Maybe your team is using it, maybe your cloud dreams demand it — or maybe, like me, you’ve been deep in the Kubernetes jungle (My blog posts about K8S) and now want a declarative friend for AWS too!

We need 3 EC2 instances on AWS, 2 on Azure, and an S3 bucket for backups. Oh — and don’t forget a VPC, IAM…
