Because Shielded VM is a type of Compute Engine VM, its quotas are
identical to those of Compute Engine.

For Shielded VM instances, the quota and limits are based on number
of vCPU. For example, a limit of 8 vCPU means you can launch a total of 4
instances of type "n2d-standard-2 (2 vCPU, 8 GB Memory)."

To learn more about Compute Engine resource quotas, including how to
check your quota, how to request an increase in quota, and how quota is
enforced, see the Compute Engine [Allocation quotas](https://docs.cloud.google.com/compute/resource-usage)
