I'll do a system d but a problem is (1) system environment, and (2) machine specs.

To normalize machine specs I will run it in a VM on the cloud.

To normalize system environment I run in docker.

I also like to run on Java for code safety and consistency.

So what I have is a VM (Java) running on a VM (Docker) running a VM, running a VM (cloud compute), running on system D. I don't think it's abstracted enough though so I'm looking to find ways to add more VMs to the equation, so as to ensure consistency. Figure if I add a few more VMs, good luck hacking that!

Would you give a short explanation of how you would try that?
