Thanks for your opinions. I'm trying to setup a Web Hosting Brand. Using a Cloud VPS will be helpful then. Right?
Cloud VPS is a regular VPS but with almost 100% uptime. This is possible by having hypervisors (physical servers) read the data from centralized storage system like SAN. This way, if the hypervisor that hosts your VPS has a malfunction and becomes unavailable, your VPS can easily be booted on the another working hypervisor. Thus, you can achieve near if not 100% uptime.
