== Solaris (operating system) ==

'''Solaris''' is a [[Unix]]-based [[operating system]] originally developed by [[Sun Microsystems]] and now maintained by [[Oracle Corporation]] after its acquisition of Sun in 2010. Known for its scalability, advanced [[ZFS]] file system, [[DTrace]] dynamic tracing framework, and strong support for [[SPARC]] and [[x86]] architectures, Solaris has been widely used in enterprise environments, particularly in data centers and telecommunications.

== Features ==

Solaris is distinguished by several key technologies. [[ZFS]] (Zettabyte File System) provides integrated [[volume management]], [[data integrity]] via checksums, and high storage capacities. [[DTrace]] allows administrators and developers to dynamically observe system behavior in production without application modification. Solaris also includes [[Solaris Zones]] ([[containers]]) for operating system-level virtualization, [[Solaris 10]] introduced [[the Solaris Service Management Facility]] (SMF) for service lifecycle management, and [[Logical Domains]] (LDoms) for hardware partitioning on SPARC systems. The [[Oracle Solaris 11]] release emphasized [[IPS (Image Packaging System)]] and a [[kernel]] hardened with [[Solaris Trusted Extensions]].

== History ==

Solaris began as a port of [[SunOS 4.x]] (based on [[BSD]]) to [[SPARC]] in 1991. SunOS 5.0 was rebranded as Solaris 2.0, transitioning to [[System V Release 4]] (SVR4) foundations. Key releases include Solaris 2.6 (1997), Solaris 7 (1998) with 64-bit support, Solaris 8 (2000), Solaris 9 (2002), and Solaris 10 (2005) – the latter bringing DTrace, ZFS, and zones. After Oracle's acquisition, Solaris 11 shipped in 2011, followed by Solaris 11.4 (2018). Oracle continues to offer Oracle Solaris as a proprietary product, with a free [[OpenSolaris]] project discontinued in 2010 in favor of the [[illumos]] fork.
