Oracle Virtual Machine ( Oracle VM )

Oracle Virtual Machine is a software implementation of a machine (i.e. a computer) that executes programs like a physical machine. Virtual machines are separated into two major categories, based on their use and degree of correspondence to any real machine. A system virtual machine provides a complete system platform which supports the execution of a complete operating system . These usually emulate an existing architecture, and are built with the purpose of providing a platform to run programs where the real hardware is not available for use (for example, executing software on, otherwise, obsolete platforms) or having multiple instances of virtual machines lead to more efficient use of computing resource, both in terms of energy consumption as well as cost effectiveness (known as hardware virtualization, the key to cloud computing environment), or both. In contrast, a process virtual machine (also, language virtual machine) is designed to run a single program, which means that it supports a single process. Such virtual machines are usually closely suited to one or more programming languages and built with the purpose of providing program portability and flexibility (amongst other things). An essential characteristic of a virtual machine is that the software running inside is limited to the resources and abstractions provided by the virtual machine—it cannot break out of its virtual environment.
