My CEO just came back from a technology conference where his head became filled with lots of ideas including the idea that we should abandon our hosted datacenters and push everything into the Cloud, specifically Amazon's. A cursory review of the offerings for this show that the databases are hosted on Amazon virtual machines that aren't officially supported by Oracle and thus require a premium support contract from Amazon. Aside from my personal feelings on the matter (that I'd much rather have a tangible set of servers that are under direct control), what are your pros/cons for pushing or not Production level OLTP databases into the cloud. I notice right now that they currently only offer 11g1 on 64-bit an not 10g 64-bit or 11g2 64-bit so it would appear they arent covering all of their bases. Presently we're RAC on 10.2.0.4 64 bit and use dataguard to a different datacenter for geographic redundancy. I note also that Amazon doesnt support RAC instances at present. His driving push is that somehow Amazon's cloud will mean better performance throughout the world as somehow the network throughput will be magically enhanced so someone in Iraq will get the same speed hitting the application as someone in California. I don't agree with that either but I dont have empirical proof. Our databases presently are highly available, highly optimized, and highly redundant. But, they aren't buzz word stamped "Cloud." Sigh.
