Virtual Machines and Virtualization
{"Image DocumentName": "Virtual Machines and Virtualization", "Image ImageDescription": "enables a single PC or server to simultaneously run multiple operating systems or multiple sessions of a single OS. a machine can host numerous applications, including those that run on different operating systems, on a single platform. host operating system can support a number of virtual machines (VM) each has the characteristics of a particular OS and, in some versions of virtualization, the characteristics of a particular hardware platform. Traditionally, applications have run directly on an OS on a PC or a server. Each PC. or server would run only one OS at a time. Thus, the vendor had to rewrite parts. of its applications for each OS/platform they would run on. An effective strategy. for dealing with this problem is known as virtualization . Virtualization technology. enables a single PC or server to simultaneously run multiple operating systems or. multiple sessions of a single OS. A machine with virtualization can host numerous. applications, including those that run on different operating systems, on a single. platform. In essence, the host operating system can support a number of virtual. machines (VM) , each of which has the characteristics of a particular OS and, in some. versions of virtualization, the characteristics of a particular hardware platform. The VM approach is becoming a common way for businesses and individuals. to deal with legacy applications and to optimize their hardware usage by maximizing. the number of kinds of applications that a single computer can handle [GEER09]. Commercial VM offerings by companies such as VMware and Microsoft are widely. used, with millions of copies having been sold. In addition to their use in server. environments, these VM technologies also are used in desktop environments to run. multiple operating systems, typically Windows and Linux.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
