ABSTRACT
The beginning of virtualization started up in the era of 1960s, which says that virtualization is the technology which is used as a splitting up and adding up of physical resources into logical resources as we want orin other words we can say that it is a technology that transfers resources from hardware into software for e.g. CPU, Memory, storage, network resources Virtualization In cloud used as scaling up and down of resources in the large amount of data that allow users to access when they need it. It allows providers to virtualize a server, storage or many physical hardware resources or data centers and they also provide various services such as infrastructure as a service (IAAS), software as a service (SAAS) and platform as a service (PAAS). Virtualization is used increasingly and performs countless benefits. As earlier, to manage our physical data centers traditional ways were used which results in more focus on physical hardware rather than on main performances. After the enhancement of virtualization, the traditional way gets improved and also reduces the cost, capex/opex i.e Capital Expenditure and Operational Expenditure.
