Would be nice if it could be used to simulate preetible vm from gcp, is it possible?
Yes, We have the plan but have not started it yet. You can see the "chaos-cloud" TODO here https://github.com/pingcap/chaos-mesh#roadmap.
Feel free to tell us your idea of doing the chaos for AWS and GCP.
If Google's strategy to catch up to AWS and Azure fails to gain them meaningful market share, I would expect them to change their behavior to succeed. It's good business.
