What is Virtualization ?

Virtualization 

what is virtualization that's a great question given that we use virtualization every day when we access the cloud and cloud services today's computers have tons of processing power including super fast CPU speeds fast RAM that's inexpensive and tons of storage capacity but is that computing power being used efficiently unfortunately the answer is no when the hardware and processing power is underutilized and the electricity is wasted virtualization helps solve the problem of underutilized resources by creating a virtualization layer between the hardware components and the user this 

enables the creation of virtual machines which are virtual computers that can run in multiple on a single set of hardware the virtualization layer creates virtual hardware components for the virtual machine also called the VM in this image you can see that the virtual machine or virtual computer needs all of the same components that a regular computer does it needs storage it needs access to a keyboard it needs network interface cards or NICs it needs processing and it needs RAM virtualization takes those physical resources and turns them into virtual resources for the virtual machine many virtual machines can be created on a single host computer in this image the computer is running two virtual machines VM one which is running the Windows operating system and VM two which is running the aboon two Linux operating system these virtual machines are on top of the virtualization layer being managed by VMware Workstationm 

Virtualization 

there are lots of benefits to virtualization increased efficiency and multitasking because you can run multiple computers instead of just a single computer running on your computer hardware you can run multiple operating systems or multiple computers on a single set of hardware it also increases manageability or the ability to move copy and isolate virtual machines sustainability with increased energy savings by using less computer hardware and therefore less electricity increased availability with the ability to snapshot virtual machines clone virtual machines and run redundant virtual machines and increased security by isolating virtual machines from one another and isolating them from the course system as well as isolating applications and the ability to run legacy applications that wouldn't be possible sometimes on a regular company computer.
