Cloud Computing Hosting
Cloud Computing is a style of computing in which dynamically scalable where virtualized resources (processors, memory, and storage) are pooled to deliver hosted services over the Internet. The term cloud computing was inspired by the cloud symbol that's often used to represent the Internet in flow charts and diagrams. The biggest advantage of cloud hosting is that it is elastic and not bound to traditional dedicated servers.
A cloud can be private or public. A public cloud sells services to anyone on the Internet. A private cloud is a dedicated environment that supplies hosted services to a single customer. Public or private, the goal of cloud computing is to provide easy, scalable access to computing resources and IT services.
In a public cloud servers are sold as Virtual Machines or virtual dedicated servers. Each virtual machine has its own allocation of processors, memory, and storage. It runs its own operation system and can be rebooted with affecting any other virtual machine. There are two major advantages of virtual machines over dedicated servers;
1) Additional resources can be added instantly without distrupting service.
2) Virtual Machines can automatically be moved to other resources upon a failure.
While virtual machines have their advantages there are applications that simply don't run well in a virtualized server environment. Large databases still run better on dedicated servers because they have complete access to the servers I/O resources. There also is a PCI compliance issue with cloud hosting. Therefore, Hybrid clouds are used to mix traditional dedicated servers with public clouds. More more information regarding hybrid clouds, go to Hybrid Clouds / Dedicated Servers.
For those customers that require higher envirnoment security or want total control over their cloud resources, there private clouds. Private clouds can be created using a group of dedicated servers (called nodes) and storage. This way the client has full control of the resources and there is added security since there are no share resources. More more information regarding private clouds, go to Virtual Private Data Centers.

"Since I switched to DedicatedServerCity a few years ago, I have not once regretted it. In fact it has been one of the best choices I have made, not only for myself, but my clients as well."
