What is virtualization?
Virtualization is the creation of an actual version of something. It may an operating system, a server, network resources, storage device. It is the process of breaking up on more physical servers into multiple virtual servers. If we using virtualization we can partition things in separate parts.
Ex: If we use hard drive in to separate partitions. Partition is the logical division of a hard drive to create, effect in two separate hard drives.
The usual goal of virtualization is to centralize administrative tasks while improving scalability and workloads.
Virtualization was first introduced in the 1960s by IBM to boost utilization of large, expensive mainframe systems by partitioning them into logical, separate virtual machines that could run multiple applications and processes at the same time. In the 1980s and 1990s, this centrally shared mainframe model gave way to a distributed, client-server computing model, in which many low-cost x86 servers and desktops independently run specific applications. While virtualization faded from the limelight for a while, it is now one of the hottest trends in the industry again, as organizations aim to increase the utilization, flexibility and cost-effectiveness in a distributed computing environment. VMWare, Citrix, Microsoft, IBM, Red Hat and many other vendors offer virtualization solutions. Virtualization provides a set of tools for increasing flexibility and lowering costs, things that are important in every enterprise and Information Technology organization. Virtualization solutions are becoming increasingly available and rich in features.
By decoupling logical resources from physical assets, virtualization can empower an exceptionally swift response to changing business conditions or changing business strategies. Virtualization can help you to:
Save money
Save energy
Save time
Reduce desktop management headaches
