That's how most of our customers use Aptible, yes. That said, we currently have our first customers running Aptible as an integration with AWS, and we believe this will be the most popular way to use Aptible in the future.
With this new product model, you integrate Aptible with your AWS account, and we provide functionality to provision high-level constructs like apps and databases that simply set up and coordinate AWS services like ECS, EKS, RDS, etc. Aptible only needs permission to write to a set of SQS queues in your account. To make sure things stay compliant, we set up AWS Config checks for every security control relevant to your chosen compliance framework(s), and maintain a set of managed IAM roles that you can assign to your dev team to ensure least-privilege access without having to constantly update IAM.
