KEMP Technologies was founded in 2000 in New York and they specialise in creating load balancing products. They offer hardware, cloud, virtual and bare metal load balancers.
One of the best things about KEMP is the offer a completely free version of their product, it isn’t a waterdown version of their product but a fully featured Layer-7 load balancer, with only one drawback, it is throttled to 20Mbps throughput. However the free appliance can be seamlessly upgraded to a paid license at any time.
A KEMP appliance is extremely easy to set up and get running within a virtual environment and can be managed via a web browser session. A great resource available from the KEMP Technologies website is templates to help you configure certain load balancing services, such an Exchange 2010/2013/2016, Microsoft RDS, VMware Horizon View, MobileIron MDM and Dell Wyse VWorkspace to name a few.
With the free version support is limited to the KEMP Community forums, templates and excellent install guides. But this hasn’t been a hindrance in the home lab or small office installations I have encountered. However, should you need it there are options you can buy to provide telephone support.
The free appliance can be downloaded from http://freeloadbalancer.com/
