Not familiar with google cloud but https://aws.amazon.com/fargate/ let's you run a docker image for long running stuff, and you can also use containers as lambdas

Fargate isn't comparable here. Aws code build batch is a similar idea to cloud build.

It's basically a distributed graph, where each node is an os/container and the edges are some sharded file system.

Codepipeline seems sightly more generic but i think it's also the same idea with less control over the os maybe...

oh AWS... :-) CodePipeline is one thing, but there's also CodeBuild https://aws.amazon.com/codebuild/

I think if you glue the two together you get an equivalent of GCP's service
