OpenSolaris (/ˌoʊpən səˈlɑːrɪs/) is a discontinued open-source computer operating system for SPARC and x86 based systems, created by Sun Microsystems and based on Solaris. Its development began in the mid 2000s and ended in 2010.
OpenSolaris was developed as a combination of several software consolidations that were open sourced starting with Solaris 10. It includes a variety of free software, including popular desktop and server software. It is a descendant of the UNIX System V Release 4 (SVR4) code base developed by Sun and AT&T in the late 1980s and is the only version of the System V variant of UNIX available as open source.
After Oracle's acquisition of Sun Microsystems in 2010, Oracle discontinued development of OpenSolaris in house, pivoting to focus exclusively on the development of the proprietary Solaris Express (now Oracle Solaris). Prior to Oracle's close-sourcing Solaris, a group of former OpenSolaris developers began efforts to fork the core software under the name OpenIndiana, and the illumos Foundation that was created at the time continues to develop and maintain the kernel and userland of OpenIndiana, and since then additional illumos distributions, both commercial and non-commercial, have appeared and are under active development.
