Kemp Loadmaster is a reliable and budget-friendly load balancer for small to medium sized organizations. It offers flexible Layer4 and Lyaer7 load balancing, SSL offloading and built-in Web Application Firewall for essential security with easy setup and a user-friendly interface and deployment options across virtual cloud and hardware environments. The technical support is good and provides immediate response.

this load balancer works as expected, although implementing it needs specific knowhow and the user interface has some complexity. we are using it mainly to loadbalance exchange servers for the outlook clients, and this has proven to work properly and in a very stable manner. we went for the virtual appliance, which runs on our vmware infrastructure smoothly and enable us to save room and HUs avoiding the traditional appliances. the LB runs in cluster, so we keep the two instances running in different datacenters for proper load balancing.
