Sun Microsystems, Inc. (Sun for short) was an American technology company that sold computers, computer components, software, and information technology services and created the Java programming language, the Solaris operating system, ZFS, the Network File System (NFS), and SPARC microprocessors. Sun contributed significantly to the evolution of several key computing technologies, among them Unix, RISC processors, thin client computing, and virtualized computing. Notable Sun acquisitions include Cray Business Systems Division, Storagetek, and Innotek GmbH, creators of VirtualBox. Sun was founded on February 24, 1982.[2] At its height, the Sun headquarters were in Santa Clara, California (part of Silicon Valley), on the former west campus of the Agnews Developmental Center.
Sun products included computer servers and workstations built on its own RISC-based SPARC processor architecture, as well as on x86-based AMD Opteron and Intel Xeon processors. Sun also developed its own storage systems and a suite of software products, including the Solaris operating system, developer tools, Web infrastructure software, and identity management applications. Technologies included the Java platform and NFS.
In general, Sun was a proponent of open systems, particularly Unix. It was also a major contributor to open-source software, as evidenced by its $1 billion purchase, in 2008, of MySQL, an open-source relational database management system.[3][4]
At various times, Sun had manufacturing facilities in several locations worldwide, including Newark, California; Hillsboro, Oregon; and Linlithgow, Scotland.[5] However, by the time the company was acquired by Oracle Corporation, it had outsourced most manufacturing responsibilities.
On April 20, 2009, it was announced that Oracle would acquire Sun for US$7.4 billion. The deal was completed on January 27, 2010.
Dot-com bubble and aftermath[edit]
During the dot-com bubble, Sun began making more money, with its stock rising as high as $250 per share.[17] It also began spending much more, hiring workers and building itself out. Some of this was because of genuine demand, but much was from web start-up companies anticipating business that would never happen. In 2000, the bubble burst.[18] Sales in Sun's important hardware division went into free-fall as customers closed shop and auctioned high-end servers.
Several quarters of steep losses led to executive departures, rounds of layoffs,[19][20][21] and other cost cutting. In December 2001, the stock fell to the 1998, pre-bubble level of about $100. It continued to fall, faster than many other technology companies. A year later, it had reached below $10 (a tenth of what it was in 1990), but it eventually bounced back to $20. In mid-2004, Sun closed their Newark, California, factory and consolidated all manufacturing to Hillsboro, Oregon and Linlithgow, Scotland.[22] In 2006, the rest of the Newark campus was put on the market.
