Providing high-availability to a XenDesktop environment provides the level of assurance organizations need when moving towards a desktop virtualization solution. Because the desktop operating environment is no longer on the endpoint, but is instead within the data center, a failure of one component has the potential to impact hundreds or thousands of users. This is a risk with any desktop virtualization solution. Because of this fact, XenDesktop is built around fault tolerant components that can be further enhanced with Citrix NetScaler to provide disaster recovery and business continuity. This Implementation Guide shows how to provide high-availability, disaster recovery and business continuity to a XenDesktop environment. The document is divided into the following sections:

• Local Availability: Configure the XenDesktop components in a highly-available configuration
• Global Availability: Configure the XenDesktop architecture to provide the best delivery for users, regardless of location
• Disaster Recovery/Business Continuity: Provide XenDesktop users with a fallback solution in the event of a major outage.
