DirectAccess Deployment Guide for KEMP LoadMaster Load Balancers

DirectAccess Deployment Guide for Kemp LoadMaster Load BalancersA few months ago I had the opportunity to work with the folks at KEMP Technologies to document the use of their LoadMaster load balancers for Windows Server 2012 R2 DirectAccess deployments. DirectAccess has several critical single points of failure which can benefit from the use of a load balancer. Typically Windows Network Load Balancing (NLB) is used in these scenarios, but NLB suffers from some serious limitations and lacks essential capabilities required to fully address these requirements. The use of an external third-party load balancer can provide better load distribution and more granular traffic control, while at the same time improving availability with intelligent service health checks.

Working with the LoadMaster was a great experience. Installation was quick and simple, and their web-based management console is intuitive and easy to use. The LoadMaster includes essential features that are required for load balancing DirectAccess servers, and advanced capabilities that can be leveraged to enhance geographic redundancy for multisite deployments.
