Has Oracle given any details about their underlying technology, other than what we assume was acquired from Nimbula and others? Do they know how to build a datacenter for IAAS/PASS at the same level as Amazon, Google, MS? Amazon and other large players have made fundamental innovations in how they construct custom X86 servers, Virtual servers & custom layer 2/3 networks at large scale. They don't just rack together Dell/HP servers & connect them with Cisco switches/routers, then slap a webui on top of it. That would just be putting lipstick on a pig. It doesn't matter if its a large pig with 64 Cpu cores.
