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.
