Citrix invests in the success of open source projects through development, evanglism and financial support. These are the primary projects we participate in today.
Apache CloudStack is open source software designed to deploy and manage large networks of virtual machines, as a highly available, highly scalable Infrastructure as a Service (IaaS) cloud computing platform. CloudStack is used by a number of service providers to offer public cloud services, and by many companies to provide an on-premises (private) cloud offering, or as part of a hybrid cloud solution.
OpenDaylight is a community-led, open, industry-supported framework, for accelerating adoption, fostering new innovation, reducing risk and creating a more transparent approach to Software-Defined Networking.
The Xen Project is the home for several virtualization related open source projects, and Xen Project is the new name for the Xen open source community. The Xen Project develops virtualization technologies powering the world's largest clouds in production and is the foundation of many commercial products. Technology developed by the Xen Project powers public clouds such as Amazon Web Services, Rackspace Public Cloud, and many others. Examples of Xen based server products include Huawei UVP, Oracle VM and Citrix XenServer. Examples of client products and appliances include QubesOS, Citrix XenClient and Netscaler. The Xen Project is 10 years old, and the technology it has created is mature and its stability and versatility is second to none.
XenServer is an open source project and community managed by Citrix. The project develops open source software for securely running multiple operating systems and applications on a single device, enabling hardware consolidation and automation to reduce costs and simplify IT management of servers and applications.
