GCP purchased CloudSimple who provides managed VMWare running on bare metal. This isn't a solution co-developed between VMWare and GCP, nor is this a 1st party VMWare solution. I'm not even sure if this is running on GCE, or if its just a re-branding of CloudSimple as GCP VMWare Engine
VMWare Cloud on AWS was built by VMWare to run on AWS ec2 bare-metal instances, and is managed by VMWare themselves.
While similar, they are different.
