Scaling to 1,000 XenApp6 servers in a single farm
XenApp is an on-demand application delivery solution that enables any Windows application to be virtualized, centralized and managed in the datacenter and instantly delivered as a service to users anywhere on any device. This means subscribers can use whatever device they choose—laptop, tablet, smartphone—but still access familiar Windows desktops and business applications that the service provider manages. XenApp enables service providers to centrally manage a single instance of each application and deliver it to users for online and offline use, providing a high-definition experience. It delivers 99.999 percent application availability and is proven with 25 million applications in production and over 100 million users worldwide.
Citrix XenApp 6 introduces exciting new enhancements for advanced management and scalability, a rich multimedia experience over any network and self-service applications with universal device support from PC to Mac to smartphone. With full support for Windows Server® 2008 R2 and seamless integration with Microsoft® App-V, XenApp 6 provides session and application virtualization technologies that make it easy for service providers to centrally manage applications using any combination of local and hosted delivery to best fit their unique requirements.
