The Virtual Data Center, Know What Not to Put in the Cloud
Tonight I was reading on the challenges of cloud computing. I’m not sure how these “security issues” with the data center cloud get blown into these kinds of issues.
The first issue is that cloud providers place several customer’s data on the same physical machine and security policy may require that the information be kept separate. First, this is the very nature of how the cloud works. If you insist on having a dedicated physical machine, don’t use the cloud, it’s that simple.
Next thing is to get over the idea that somehow the cloud virtual machines are different functionally than a dedicated server. Just because the virtuals share a physical machine doesn’t mean they can interact with each other any more than physically separate machines do, nor can they access storage other than what belongs to them.
The second issue is that, because the virtual machines can be dynamically moved between hosts in the cloud, you can’t know where your data physically is stored. In the case of our own cloud, regardless of what host is running the virtual, the data is always stored in the same physical location. The virtual may move but the storage for it doesn’t.
