What Not to Move to the Cloud
Managed private cloud computing is the hottest buzzword in technology today. Everyone is already considering on moving their data to this cost-effective solution. But since it is a fairly new concept, it still has a lot of room for improvement. One of the challenges to cloud computing is security. And the so-called security issues have been blown into several different concerns that are making some people a bit more cautious about moving to the cloud.
One issue is that cloud providers normally put their client’s data in the same physical machine as all their other clients. The security policy may need to keep the information separate. First of all, this is the exact nature of cloud computing. For those who insist on operating from a dedicated physical machine, the cloud is definitely not for them. Ideally, cloud providers will have security measures in place to keep data from getting compromised even when it is located in the same physical machine as all other data.
The next issue that people have to get over and that cloud providers have to address is the idea that cloud virtual machines somehow work differently than dedicated servers. Just because multiple virtual machines share a single physical machine doesn’t necessarily follow that they are capable of interacting with one another. Just like physically separate machines, they are incapable of accessing storage that doesn’t belong to them.
Another issue is that because VMs can be dynamically moved between hosts, clients cannot know where their data is physically stored. In the case of a cloud, regardless of which host is running the VM, information is still stored on the same physical location. Virtual machines move but storage stays in place.
