Kemp recently released a free version of their virtual LoadMaster (VLM) load balancer solution. It is just like a regular VLM with some restrictions of course. There’s no High Availability support in the free LoadMaster, there’s only web-based support and you cannot update the firmware to a newer version for example. Also the bandwidth is limited to 20Mbit (L7) throughput with 50 transactions (TPS) 2K SSL keys.
However, it does support the nice features such as Global Server load balancing, the Application Firewall Pack and the Edge Security Pack. This makes it a perfect solution for small organizations, for lab environment or for regular test environments. It is possible though to upgrade the free LoadMaster to a regular device, making it also a perfect solution for a Proof-of-Concept. When finished the POC you an easily bring the LoadMaster to production by upgrading the license.
