Distributed components configuration
You can distribute the components of your deployment among a greater number of servers, or provide greater scalability and failover by increasing the number of controllers in your site. You can install the management consoles on separate computers to enable you to manage your deployment remotely. A distributed deployment is necessary for an infrastructure based on remote access through NetScaler Gateway (formerly called Access Gateway).
For more information about Citrix NetScaler Gateway for secure remote access, see the product-specific documentation.
Multiple site configuration
If you have multiple regional sites, for example one in Europe and one in the US, you can use Citrix NetScaler to direct user connections to the most appropriate site and StoreFront to deliver desktops and applications to users.
In the following example, a XenDesktop was created in two data centers. Having two sites globally, rather than just one, minimizes the amount of unnecessary WAN traffic. You can use StoreFront to aggregate resources from multiple XenDesktop sites to provide users with a single point of access with NetScaler. Citrix NetScaler accelerates application performance, load balances servers, increases security, and optimizes the user experience. In this example, two NetScalers are used to provide a high availability configuration. The NetScalers are configured for Global Server Load Balancing and positioned in the DMZ to provide a multi-site, fault-tolerant solution. For more information on highly available multi-site configurations with StoreFront, see Set up highly available multi-site store configurations.
A separate Studio console is required to manage each site; sites cannot be managed as a single entity. You can use Director to support users across sites.
