Direct access Server
What is Direct access server?
Direct Access also known as Unified Remote Access, is a VPN-like technology that provides intranet connectivity to client computers when they are connected to the internet.
It was initially introduced in Windows server 2008 R2 supporting Windows 7 and Windows 8 Enterprise clients .
Direct Access clients are designed to connect automatically as soon as the computer connects to the Internet, initiating a VPN if the client detects that its not connecting from within the network.
Load balancing direct access
Remote access is vital to organisations of any size and any level of downtime is not acceptable.
jetNEXUS offers 3 key advantages for load balancing a Microsoft Direct Access server environment.
- Data center resiliency
- Direct Access Server resiliency
- Simplification of implementation with NLS
Data center resiliency
The jetNEXUS GSLB Global Server load Balancer can load balance client connections to the datacenter using multiple methods such as:
- Geolocation – load balance to the closest Datacenter. This can also be used for custom defined networks and locations
- Active-Active/ Active- Passive – Spread the load across the data centers based on number of connections or some other health check. Alternatively send all clients to one Data center unless its down (or not meeting health check requirements) in which case sent it to the other data center.
Microsoft Direct Access Server resilience and scalability
Once the connection has arrived at the specific data center the load balancer can then choose what Direct access server to send the request to based on a choice of load balancing methods
- Round robin
- Least connections
Simplify DirectAccess Deployment with NLS response
The jetNEXUS load balancer when load balancing DirectAccess can either load balance the NLS (Network Location Server) OR in fact act as a NLS (Network Location Server).
By configuring the jetNEXUS load balancer to respond to NLS requests the Client will know whether its on the local network or not without the administrator having to provision a separate NLS server.
