Google doesn't use VMs internally and they probably don't have a scalable SAN (EBS competitor) either, so they don't have as much of an advantage as you might think. Google bet big on a "legacy-free" stack (GFS, MapReduce, BigTable, etc.) and that has worked out great for their internal services but external customers just aren't willing to adopt it (see App Engine).

They've got Ganeti, but I don't know exactly what they use it for.
