Google should one-up Amazon and get into the Datacenter As A Service market. Service segments: normal cages (I'd rather lease cages from Colorful Pipes, Inc than Equinix), pay-n-go turnkey same-hardware in 3 georedundant locations, and lease-by-rack in multiples of 10 pre-populated racks (racks specified as compute-only or storage-only with 10G interconnects between racks).
