Virtualization and cloud computing are the technologies that go hand in hand. Cloud computing is an emerging technology that represents a new computing paradigm. It will enable individuals and organizations to access a pool of computing resources in pay as you use fashion. This technology helps small and medium companies or any company on the earth for that matter to eliminate the need for capital investment. Cloud computing offers many service models such as Platform as a Service (PaaS), Infrastructure as a Service (IaaS) and Software as a Service (SaaS). It bestows many deployment models such as private could, public cloud, community cloud and infrastructure cloud. With this technology the computing resources have been commoditized in the similar fashion which commoditize water and electricity. However, cloud computing cannot become affordable solution without the technology virtualization. Therefore virtualization is the technology on top of it cloud computing is built. Virtualization is the process of creation of virtual counterpart of something like hardware, network, storage device, and operating system. Cloud computing is growing trend in internet technology that enable on demand network access to a shared pool of configurable resources. The virtualization is a core part of cloud computing which enables physical resources to partition into virtual resources so that they can be shared among individual virtual machines. This sharing of virtualized resources can reduce wastage of storage, server and physical machines. The virtualized environment in cloud computing consists of the underlying hardware, hypervisor and virtual machines (VMs) which enables intellectual IT resources on demand dynamic allocation of resources such as network, storage, application, server and client. Virtualization using hypervisor becomes significant as a way to develop system security, provide greater flexibility and reliability. Currently, there is an increased desire to use virtualized systems in enterprise in order to reduce cost and more efficiently utilize resources. This paper describes different types of hypervisor and virtualization techniques, how it helps to expand elasticity of the resources in cloud computing environment.
