In computing, virtualisation refers to the act of creating a virtual (rather than actual) version of something, including virtual computer hardware platforms, storage devices, and computer network resources
1. OS Virtualisation
Operating system virtualisation refers to the use of to allow system to run multiple instances of different concurrently, allowing you to run different requiring different operating systems on one . The operating systems do not interfere with each other or the various applications.
2. Application-Server Virtualisation
Server virtualisation is the partitioning of a physical into smaller virtual servers to help maximise your server resources. In server the resources of the server itself are hidden, or masked, from users, and software is used to divide the server into multiple virtual environments, called virtual or private servers. This is in contrast to one server to a single application or task.
3. Application Virtualisation
Application virtualisation is software technology that encapsulates computer programs from the underlying operating system on which it is executed. A fully virtualised application is not installed in the traditional sense, although it is still executed as if it were. The application behaves at run time like it is directly interfacing with the original operating system and all the resources managed by it, but can be isolated or sandboxed to varying degrees.
4. Network Virtualisation
Network virtualisation is a method of combining the available resources in a network by splitting up the available bandwidth into channels, each of which is independent from the others, and each of which can be assigned (or reassigned) to a particular server or device in real time. Each channel is independently secured. Every subscriber has shared access to all the resources on the network from a single computer.
5. Storage Virtualisation
Storage virtualisation is the amalgamation of multiple network storage devices into what appears to be a single storage unit. Storage virtualisation is usually implemented via software applications and often used in (storage area network), a high-speed sub network of shared storage devices, and makes tasks such as , , and recovery easier and faster.
Benefits of Virtualisation
· Increased security.
· Longer hardware refresh cycles.
· Allows moves to the cloud.
· Efficient IT infrastructure.
· More efficient software installations and hardware deployment.
· Less energy consumption and maintenance cost.
· Immediate access to files and applications.
· Quick and easiest way of backup and disaster recovery.
· Less operating costs.
· Ability to use thin clients (thin client is a lightweight computer that is purpose built for remote access to a server. All computations are done on the remote server).
· Less time spent on providing support to desk side.
