|Citrix System headquarters 1991–1997|
Citrix Systems, Inc. is an American multinational software company founded in 1989 that provides server, application and desktop virtualization, networking, software-as-a-service (SaaS), and cloud computing technologies, including Xen open-source products.
Citrix currently services around 330,000 organizations worldwide and is based in Fort Lauderdale, Florida, in the Miami metropolitan area, with subsidiary operations in California and Massachusetts, and additional development centers in Canada, Germany, Denmark, the United Kingdom, India and Australia.
Citrix was founded in Richardson, Texas, in 1989 by former IBM developer Ed Iacobucci with $3 million in funding. Following its initial setup and development, Iacobucci moved the company to his former home of Coral Springs, Florida.
Many of the original founding members had participated in the IBM OS/2 project. Iacobucci's vision was to build OS/2 with multiuser support. IBM was not interested in this idea, so Iacobucci left. Iacobucci was offered a job at Microsoft as chief technical officer of its networking group but turned it down to start his own company.
The company's first product was Citrix MULTIUSER, which was based on OS/2. Citrix licensed the OS/2 source code from Microsoft, bypassing IBM. Citrix hoped to capture part of the UNIX market by making it easy to deploy text-based OS/2 applications. The product failed to find a market. This was due in part to Microsoft's declaring in 1991 that it was no longer going to support OS/2.
Roger Roberts was appointed the CEO of Citrix in 1990. Roberts, a Texan, came from Texas Instruments.
From 1989 to 1995, the company did not turn a profit. In 1989 and 1990 there was no income at all. Between 1991 and 1993, Citrix received funding from both Intel and Microsoft as well as venture capitalists. Without the help of this funding, Citrix would not have survived.
In 1993, Citrix purchased the product "NetWare Access Server" from Novell. It was a remote-access application built on DOS and Quarterdeck Expanded Memory Manager. It provided desktop and applications from the server to multiple users in a similar way that terminal servers still do. Citrix developed the product further and released it as WinView. It became Citrix's first successful product.
The company went public in December 1995.
The Citrix and Microsoft relationship is based upon a 20-year alliance that began in 1989 when Citrix licensed the OS/2 source code.
Citrix obtained a source code license to Microsoft's Windows NT 3.51. In 1995, Citrix shipped a multiuser version of Windows NT with remote access known as WinFrame. This product was a unique offering targeting the needs of large enterprises.
During the development of WinFrame for Windows NT 4, Microsoft decided that it did not want to license Windows NT 4 source code to Citrix. Microsoft considered to build its own version of WinFrame. Citrix and Microsoft entered negotiations about how best to resolve this dilemma. After negotiations, Microsoft agreed to license Citrix technology for Windows NT Server 4.0, resulting in Windows Terminal Server Edition. Citrix agreed not to ship a competing product but retained the right to sell an extension to Microsoft's products, initially under the name MetaFrame. This relationship continued into the Windows 2000 Server and Windows Server 2003 eras, with Citrix offering Metaframe XP and Presentation Server. On February 11, 2008, Citrix changed the name of its Presentation Server product line to XenApp.
The core technology that Microsoft did not buy was the ICA protocol. Microsoft derived the work for RDP (T.share) protocol from NetMeeting, which originally derived it from a deal with PictureTel (now known as Polycom).
In January 2008, Citrix announced an expanded alliance with Microsoft to deliver a set of virtualization solutions to address the desktop and server virtualization markets to ensure broad interoperability between their technologies.
In February 2009, Citrix extended its collaboration with Microsoft in the server virtualization market with “Project Encore”. This was heralded by a new product, Citrix Essentials, that offers advanced management for Microsoft Windows Server 2008 Hyper-V. Joint marketing, training and channel activities were conducted with Microsoft.
In July 2009, Citrix and Microsoft announced joint plans to simplify desktop computing by extending their desktop virtualization partnership.
These plans included:
- Technology integration so enterprise IT organisations can manage both distributed and centrally hosted applications using Citrix XenApp and Microsoft System Center Configuration Manager
- Extension of XenApp support for Microsoft Application Virtualization (App-V) to enable self-service delivery of applications on any device using Citrix Receiver and Citrix Dazzle
Citrix invests in an ongoing Corporate Giving Program focusing on education, economic development and technology advancement.
