Add Compute
TL;DR
NodeOps Network's Compute Marketplace is intended to support providers who own and register machines they control. However, it doesn't differentiate between a virtual machine (VM) or a piece of hardware. This means that it can support VM resellers.

While it's unlikely that you have idle reserved VM instances, if you do, you certainly don't want them to cost rather than earn. You can configure VMs and add them to the Marketplace as this GCP tutorial demonstrates.
