This white paper focuses on the fault tolerant and high-availability options integrated with Citrix XenApp 6.5 as they align with three different focus areas:
- Layer 1 – Application Availability: Users should always be able to work with an available hosted shared desktop or application.
- Layer 2 – High Availability: Failures within a site should not impact desktop or application availability.
- Layer 3 – Business Continuity/Disaster Recovery: The loss of an entire site should not prevent users from accessing their desktops or applications.
By focusing on three distinct layers, an organization can feel confident in the operational availability of the architecture, even in the event of a catastrophic failure.
