`Virtualization 101
`What is virtualization? Simply put, it’s the process of creating a virtual, rather than physical, version of
`something. Virtualization can apply to computers, operating systems, storage devices, applications, or
`networks. However, server virtualization is at the heart of it.
`
`IT organizations are challenged by the limitations of today’s x86 servers, which are designed to run just
`one operating system and application at a time. As a result, even small data centers have to deploy many

`
`servers, each operating at just 5 to 15 percent of capacity—highly inefficient by any standard.
`
`Virtualization uses software to simulate the existence of hardware and create a virtual computer system.
`Doing this allows businesses to run more than one virtual system – and multiple operating systems and
`applications -- on a single server. This can provide economies of scale and greater efficiency.

`
`The Virtual Machine
`A virtual computer systems is known as “virtual machine” (VM): a tightly isolated software container with an
`operating system and application inside. Each self-contained VM is completely independent. Putting
`multiple VMs on a single computer enables several operating systems and applications to run on just one
`physical server, or “host”.
`
`A thin layer of software called a hypervisor decouples the virtual machines from the host and dynamically
`allocates computing resources to each virtual machine as needed.
`
`Key Properties of Virtual Machines
`
`VMs have the following characteristics, which offer several benefits.
`
`Partitioning
`
`Run multiple operating systems on one physical machine
`
`Divide system resources between virtual machines
`
`Isolation
`
`Provide fault and security isolation at the hardware level
`
`Preserve performance with advanced resource controls
`
`Encapsulation
`
`Save the entire state of a virtual machine to files
`
`Move and copy virtual machines as easily as moving and copying files

`
`Server Consolidation
`Using server virtualization, a company can maximize the use of its server resources and reduce the number
`of servers required. The result is server consolidation, which improves efficiency and cuts costs.

`
`It’s Not Cloud Computing
`Cloud computing is not the same thing as virtualization; rather, it’s something you can do using
`virtualization. Cloud computing describes the delivery of shared computing resources (software and/or
`data) on demand through the Internet. Whether or not you are in the cloud, you can start by virtualizing
`your servers and then move to cloud computing for even more agility and increased self-service.
