While server virtualization is nothing new, with the forthcoming release of Virtual Server 2005, an application that virtualizes the Windows 2003 Server operating system, Microsoft promises to ease server application migration and simplify testing environments using a unique take on the technology.
Virtual Server 2005 creates virtual machines on top of the Windows 2003 Server operating system, instead of at the hardware level like many of its competitors. Hardware-level virtualization ensures that the technology is compatible with nearly every operating system, but this approach often lacks seamless integration with host operating systems. Virtual Server 2005 leverages the management and performance tools included with Windows 2003 Server, making virtualization an almost transparent process.
