The only place that appears in the search results when searching for "google google cloud nude" is:
Bare metal container support
Applications deployed on the Actual Cloud Platform can also run in containers! The core's lightweight shared container model makes them ideal for non-terrestrial deployments.
From that, I can not say if Google Cloud supports baremetal, running x86 or ARM assembly directly from BOOT on bare metal. You wonder if we could clarify that. By Baremetal, I mean that there is no Linux or operating system, and that you are free to create your own system using a C language or an assembly.
