What is VPS?
A virtual private server (VPS) is a “slice” of a real physical server which runs its own operating system and is completely isolated from the rest of the system. Each VPS is given a share of the memory, storage, and CPU time of the physical server as well as its own IP address. Many hosting providers are beginning to offer VPS packages at rates that are approaching that of shared hosting.
A2hosting is providing Ubuntu VPS Servers from $14.95/month
