Solaris (originally called SunOS) is a high-end workstation operating system developed by Oracle (formerly Sun Microsystems, Inc. who were bought out by Oracle in 2010). Solaris, formerly known as Suntools, was introduced in the mid-1980s using Sun's own Sun-3 workstation. Originally it used its own window manager, then using OpenWindows, then CDE, and then (as now) GNOME.
In 2005, OpenSolaris was released by Sun. When Oracle acquired Solaris, it was announced that OpenSolaris would be discontinued and Solaris 11 would be released under a proprietary license.
