This is something we support as well. You're correct that most of our documentation (including quickstarts) focuses primarily on web-facing apps.

Our current modules support running Python jobs using Fargate/ECS and Lambda (using Docker containers or packaged zip files).

Today, it is possible to pause workloads by destroying the app (nullstone down --app=<app>). Obviously, that's not ideal and we do have plans to support pausing workloads to reduce costs.
