VMware, Inc. is a software company, well known in the field of system virtualization and cloud computing. VMware's software allows users to create multiple virtual environments, or virtual computer systems, on a single computer or server. Essentially, one computer or server could be used to host, or manage, many virtual computer systems, sometimes as many as one hundred or more. The software virtualizes hardware components such as the video card, network adapters, and hard drive. For businesses, this is especially useful for setting up multiple server systems without having to purchase separate hardware for each of them. They can create virtual servers using VMware's software to save time and money.
VMware released its first software product, called VMware Workstation, in May 1999. In 2001, they entered the server market by releasing VMware GSX Server and VMware ESX Server. In April 2011, VMware entered the cloud computing market by releasing Cloud Foundry, an open source platform-as-a-service software system. This cloud computing system was designed to support applications built on Java, Ruby on Rails, Sinatra, and others, and provide support for MySQL, MongoDB, and other database platforms. Today, VMware develops and markets many virtualization software programs, mostly aimed towards business use, but home users can use some of their software as well. Notable software titles include VMware ESX and VMware ESXi, VMware vCloud, VMware ACE, and VMware ThinApp.
