Citrix Systems has announced details of its expanded alliance with Microsoft to offer full support for Microsoft Windows Server 2008 and Windows Server 2008 Hyper-V.

This will help ensure interoperability and cross compatibility with the Windows platform for both desktop virtualisation solutions with Citrix XenDesktop™ as well as for server virtualisation solutions with Citrix XenServer.
The announcement further extends the company’s long-standing support for the Windows Server platform as the foundation for its flagship product Citrix Presentation Server.
Presentation Server provides a complete system for delivering Windows-based applications in the enterprise. The 18-year relationship between the companies, as well as the commitment to continual innovation on the Windows platform has vastly expanded interoperability and further extends the array of Citrix dynamic virtualisation services for Microsoft customers.
"We’ve built a tremendous partnership with Microsoft by helping customers gain greater value from their investments in Microsoft technologies. Extending our innovations to Windows Server 2008 and Windows Server 2008 Hyper-V enables us to continue to deliver the industry’s broadest virtualisation infrastructure that leverages the Windows platform,” says Mark Templeton, president and CEO, Citrix Systems.
“The datacentre is rapidly becoming the head-end for delivering applications and desktops from a dynamic server infrastructure. Providing expanded choice and powerful solutions for desktop, application and server virtualisation demonstrates Citrix leadership and our shared vision with Microsoft.”  
Citrix virtualisation infrastructure products leverage a broad array of “dynamic virtualisation services” that provide core components of an end-to-end virtual infrastructure – from servers to applications to desktops. These enabling technologies range from core innovation in virtual delivery protocols to breakthroughs in application workload streaming. Upcoming dynamic virtualisation services such as real-time virtual machine (VM) streaming, VM interoperability, high-performance VM storage and VM high availability will allow Citrix to further extend Windows Server 2008 Hyper-V in the future through XenServer for server virtualisation and XenDesktop for desktop virtualisation.  
As part of the company’s VM interoperability services, Citrix is also developing technology to enable the portability of virtual machines between XenServer and Windows Server 2008 Hyper-V. By supporting both the Xen hypervisor and Windows Server 2008 Hyper-V, Citrix will allow IT organisations to leverage heterogeneous virtualisation environments for different workloads, datacentres, or business units within an organisation.
“Microsoft and Citrix share a common vision with a focus on developing an end-to-end computing environment that is flexible, dynamic and responsive to business change,” said Bob Muglia, senior vice president of the Server and Tools Business at Microsoft. “By helping to ensure interoperability of existing and new technology platforms such as Windows Server 2008, we move beyond technical and total cost of ownership value to delivering greater business agility and strategic value for all of industry partners.”
