Hypervisor's and Virtual Machines

Virtualization is one of the important technology for cloud computing. Without virtualization cloud computing could not be possible. Virtualization provides the resource consolidation for the cloud service providers. The service providers and users can manage there resources very efficiently. The resources (Storage, Network & Processors) can be divided and use as per the use.

Types of Virtualiazation

1. Server Virtualization
2. Network Virtualization
3. Storage Virtualization
4. Desktop Virtualization
For implementing virtualization a software is needed called as Hypervisor or Virtual Machine Manager (VMM). The physical resources can be divided into virtual resources. The cloud Service providers create different virtual machines on a physical server as per the number of users and their need.
There are two types of VMM
