HYPERVISOR 101: GETTING TO KNOW YOUR HYPERVISORS Having a virtualization management strategy is very important to a successful move to the cloud. There is a strong correlation between cloud adoption and the deployment of multiple hypervisor platforms. Taking advantage of multiple hypervisor platforms enables customers to benefit from cost, density, and performance differences between hypervisors. What is a Hypervisor? Definition from Wikipedia: A hypervisor or virtual machine monitor (VMM) is a piece of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor is running one or more virtual machines is defined as a host machine. Each virtual machine is called a guest machine. The hypervisor presents the guest operating systems with a virtual operating platform and manages the execution of the guest operating systems. Multiple instances of a variety of operating systems may share the virtualized hardware resources. SO WHAT WORKS BEST FOR YOUR ENTERPRISE?

PERFORMANCE This type of hypervisor is deployed as a bare-metal installation. This means that HARDWARE COMPATIBILITY the first thing to be installed on a server as the operating system will be the hypervisor. The benefit of this software is that the hypervisor will communicate directly with the underlying physical RELIABILITY server hardware. VIRTUALIZATION HYPERVISOR MANAGEMENT Hosed (Type II) Hypervisor. The software is not installed onto the bare-metal, but instead is loaded on top of an already live operating system. For example, a server running Windows Server 2012 can have vSphere 5.5 installed on top. There is an extra hop for the resources to take when they pass through to the VM, the latency is minimal with today's modern software enhancements.
