The fact that it works with an existing docker-compose.yaml and will provision itself on a cloud for you is pretty compelling I think.

I have tried the Docker AWS ECS plugin for deploying your compose stack, and it's buggy.

The AWS ECS CLI would deploy docker-compose files in V1. V2 (now called Copilot) has shifted away from this, and it uses a custom manifest YAML file. Copilot isn't bad.

Most of the platforms I work on have a docker-compose stack with Postgres, a backend API, a frontend, and potentially ancillary services. Anything that integrates well with this is a godsend tbh, because otherwise you need to maintain two sets of configuration and keep them in sync.
