今日、某所でブロケードの Public/Priave Cloud federation の話をしたが、MS も同じ話(リンクは前の記事を参照)をしている。
Now, when we think about the gap from, say, the private cloud and your own private datacenter to a public cloud, there's a lot to think about here. Sometimes, when people talk about private and public cloud and think about what it means to connect between those, they talk about moving VMs between a private cloud and a public cloud, and you certainly need to do that. That's certainly an important part of what is required, to be able to take existing OS images, existing application images, and move them up into a public cloud, a shared public cloud environment. But that's just such a tiny part of overall problem. When you think about the potential of utilizing shared resources that exist either in hosted or Microsoft-run datacenters, there's a lot of amazing potential that can come for applications that only run once in a while and don't need to have any kind of dedication of hardware, or for incremental capacity requirements, or to utilize some spare capacity that might exist inside those systems at a lower price. Those are all great advantages. Also, services will be delivered by vendors to you that are running in the cloud, and you'll need to integrate those into your overall operational environment.
