Virtualization:

Virtualization is the process of creating a software-based presentation of some object rather than a physical one. Virtualization can apply to applications, servers, storage, and networks and it is the absolute most effective way to reduce IT expenses while boosting effectiveness and deftness for every single size business.
Virtualization can expand IT agility, flexibility, and scalability while creating significant cost savings. Workloads make use of faster, performance and availability increases and operations automated, resulting in IT that is simpler to manage and less costly to oversee and less expensive to claim and work.
