Cloud

Cloud is the new term companies large and small are kicking around. There is no true definition on what a cloud is or how it is supposed to be designed and in our opinion the term "cloud" that applies to VPS hosting is no different then a VPS that has failover, redundancy or backup. So coining a the new term "cloud" and the extra hype is completely not necessary.

A typical cloud setup runs on the KVM, XEN, or VMware platform. The difference is on the type of hardware that is used. Instead of having storage located on the host server all data is stored on much larger SAN/NAS array with multiple disks. Raid is used to prevent disk failure in the physical array and in the best case scenario a second array is added incase the entire array fails. The host server accesses the storage via Ethernet. in the event of a host server failure spare host servers are on standby to startup when needed. Downtime during the failure would be a reboot of your operating system.
At R the Company our US cloud setup runs on the KVM platform with two storage arrays.

The advantage of cloud is a truly redundant environment. All aspects of hardware failure are 100% covered.
If you are looking for a 0 downtime solution this is truly it. Cloud hosting costs much more than standard vps server because of all the additional hardware required.
