Solaris Operating System
Solaris is a Unix-based operating system introduced by Sun Microsystems in
1992 as the successor to SunOS.
Solaris is known for its
scalability, especially on SPARC systems, as well for
being the origin for many innovative features such as DTrace and ZFS.[1][2] 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
