Is there a Windows equivalent of the HAProxy for virtual load balancing?
I want to load balance a bunch of VMs, but don't have any Linux boxes available. Typically, afaik, it's done with HAProxy on Linux.
Is there an HAProxy equivalent on Windows? (free, open-source if possible).
You could use Microsoft Network Load Balancing. It works well (we've used it for a few years), however its Layer 3/4 AFAIK - ie it won't detect if your IIS is down.
Another option is to use ISA server infront of it but that comes with another set of issues i.e. it becomes a SPOF
A linux VM running something like HAProxy, Pound, Varnish etc. might fit your needs.
