Virtualization

• Virtualization solves the problem of acquisition of server hardware nad applications not fully utilizing server hardware (when applications had a one-to-one relationship with servers)
• Virtualization allows for the partitioning of server hardware with the use of a hypervisor by enabling each virtual machine (VM) to use a slice of the central processing unit (CPU) time and share random access memory (RAM).
• Due to virtualization, we now have a many-to-one relationship with applications to servers.
• Due to virtualization, we can now fit many applications (operating systems) onto one physical server called physical host hardware.
• Due to virtualization, each operating system believes that it is the only process running on the physical host hardware (physical server), thanks to the hypervisor.
