Microsoft’s Hyper V has been introduced to change the way, virtual machines interact with the physical hardware. This new technology has enabled the manufacturer to compete with other different server virtualization products and services available in the market. It has provided additional capabilities to the IT sector. Hyper V has the ability to offer better support to the host functionality, support for the guest sessions, administration support and improvements in the reliability of the server.
Microsoft has managed to make major improvements to the virtual host capabilities of Hyper V are the core functional additions to Windows Server 2008. These improvements relate to security, reliability and performance. The most significant addition to Hyper V is the new virtual switch that provides greater flexibility for managing the network communication among guest images and internetworking infrastructure of an organization.
Hyper V and Windows Server 2008 influence the in-built capabilities of Windows 2008 along with specific Hyper V components for the purpose of improvingsupport, operation, administration and management of a Hyper V host server. Alike any other application server in the Active Directory environment, server can be managed and administered when Hyper V host server is joined to a Microsoft Active Directory. Centralized security management is possible through use of Active Directory units, user admins. and groups. Same tools organizations used for management and monitoring of existing Windows server systems can be used to monitor Hyper V host server. Security policies, back-up procedures, patch management and corresponding tools and utilities that are used to support Windows Server systems can be used to support Hyper V host server system. In short the Hyper V host server transforms into another managed Windows server overall on the network.
It important to run a Hyper V host server on 64 bit system. This is for providing more memory in the host server to distribute among guest sessions. Previously, a 32 bit host server was limited to approximately 4 Gb RAM memory and the ways to divide the memory into different guest sessions were limited, but with 64 bit host servers supporting 8Gb, 16 Gb or more, guest sessions can easily consume 4Gb or 8Gb memory, yet leave ample room for other guest sessions and functions. All the guest sessions on a Hyper V administration host resides within a single server. Hence, the virtual switch capability built in to thw Hyper V Administration tool enables the Hyper V administrator to create special network segments to ensure the virtual guest sessions to specific network adapters in host servers to ensure that the virtual guests can be connected to network segments to meet the needs of the organization.
Today, many web hosting companies provide Hyper V technology with their VPS packages.
