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, 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.



Solairs is free. Both Regular Solaris and OpenSolaris

Solaris with support is often less expensive than Red Hat with support on the same hardware.

Linux sometimes is faster than Solaris when running on the platform for which it was originally designed: A single 32-bit x86 CPU PC. When you get to multiple CPUs, multiple cores, etc. Solaris will usually be better. Even on the original Linux target platform, Solaris usually wins the speed battle.

Solaris 10 is secure and certified as secure.
