Enhanced Multisite Site Selection for Windows 10
Microsoft first introduced multisite DirectAccess in Windows Server 2012 to address the needs of enterprise organizations to provide geographic redundancy for their remote users. Multisite DirectAccess allows administrators to place servers in multiple physical locations to reduce crucial single points of failure in their DirectAccess architecture. When multisite DirectAccess is configured, Windows 8.x/10 clients are aware of all deployed entry points in the organization and will automatically select the entry point closest to them.
The native site selection process is very basic and often yields unexpected results. Commonly DirectAccess clients will select an entry point in a suboptimal location. Integrating DirectAccess with a Global Server Load Balancer (GSLB) like the KEMP LoadMaster GEO is an effective way to ensure that DirectAccess clients always connect to the best entry point in the enterprise. GEO monitors entry points for availability and responds to DirectAccess client DNS requests with the IP address of the entry point nearest them using IP geolocation. Furthermore, GEO enables support for important use cases such as weighted distribution and active/passive failover. KEMP GEO enables true geographic redundancy and intelligent, granular traffic distribution for DirectAccess client connections.
