Solaris is a Unix operating system originally developed by Sun Microsystems, which superseded their earlier SunOS in 1992. Oracle Solaris, as it is now known, is owned by Oracle Corporation after Oracle's acquisition of Sun in January 2010.
Solaris is known for its scalability, especially on SPARC systems, and for originating many innovative features such as DTrace and ZFS. Solaris supports SPARC-based and x86-based workstations and servers from Sun and other vendors, with efforts underway to port to additional platforms.
Solaris is certified against the Single Unix Specification. Although it was historically developed as proprietary software, it is supported on systems manufactured by all major server vendors, and the majority of its codebase is now open source software via the OpenSolaris project.
