Concerning Cloud Computing, virtualization is a technique for creating a virtual platform of storage devices and the server OS. The hypervisor manages the shared physical hardware resources between the guest OS & the host OS. Hence knowing this concept proves to be very vital for an individual. The machine that is used to create the foundation of a virtual machine is called the Host Machine and the virtual machine is labeled as the Guest Machine. It involves embedding virtual machine software into the server's hardware components. It is the abstraction of computing resources from the software that uses cloud resources. Virtual Machines provide an environment that is logically separated from the underlying hardware. The core technology that provides cloud service and deployment models, with the flexibility of “capacity on demand” and “pay as you go” computing resources, is virtualization. Virtualization began in the 1960s, as a method of logically dividing the system resources provided by mainframe computers between different applications. Virtualization helps the user make use of multiple machines sharing one single physical instance of any resource across the network of other users respectively using their machines. Virtualization has its own set of benefits, like server consolidation and better use of hardware resources. Creating a virtual machine over existing operating system and hardware is referred as Hardware Virtualization. Although virtualization, as a form of technology has existed since the 1960s, only recently with the advent of cloud computing has it become a staple in the vocabulary of those involved in the IT industry. Virtualization translates to creating a virtual counterpart of an existing system such as a desktop, server, network resource or an operating system. Gravity. When it comes to performing any tasks, chances are that the system might malfunction at a critical time. Introduction to Virtualization in Cloud Computing. The process can also be explained with the help of hypervisor which helps cloud users access the cloud server. Streamlining the IT cost and minimizing the IT administration structure.
