Virtual Servers

  • What is a virtual server?

    A virtual private server (VPS, also referred to as Virtual Dedicated Server or VDS) is a method of splitting a server. Each Virtual Server can run its own full-fledged operating system, and each server can be independently rebooted. The practice of partiti oning a single server so that it appears as multiple servers has long been common practice in mainframe computers, but has seen resurgence lately with the development of virtualization software and technologies for other architectures. The server administr ator uses a software application to divide one physical server into multiple isolated virtual environments.

  • Why is a virtual server beneficial?
    • Less hardware to purchase. If you can run 3 servers on a single piece of server hardware, then you can save money.
    • Less hardware means less heat, which saves you money on cooling
    • Fewer servers mean lower electricity costs
    • Less hardware to maintain
    • Less physical space taken up by servers
    • Quicker Disaster Recovery
  • Security & backup
  • Suppose for a moment that a physical server is running four virtual servers and one of those servers gets a virus. The good news is that unless that virus has been specifically designed to attack the Virtual Server software then the virus will be isolated to the virtual server that contracted it. Backing up your servers couldn't be simpler. With no need to purchase additional hardware you can simply keep a copy of your crucial Virtual Server safely stored.
