Machine type support
You can deploy FortiGate for GCP as VM instances. Supported machine types may change without notice. Currently FortiGate supports standard machine types, high-memory machine types, and high-CPU machine types with minimum 1 vCPU and 3.75 GB of RAM and maximum 96 virtual CPUs (vCPUs) and 624 GB of RAM in the predefined machine type lineup. You can also customize the combination of vCPU and RAM sizes within this range. See Predefined machine types.
You can see latest supported machine types under machine type selection if you try to launch FortiGate from the marketplace listing or Compute Engine portal.
