Loadbalancing with Opensolaris - or: PSARC 2008/575
An nice addition to the networking functionality has found its way into the Opensolaris codebase: PSARC 2008/575 ILB: Integrated L3/L4 Load balancer. This code enables Opensolaris to act as a simple load balancing device. It already contains features like acting as a loadbalancer in NAT or direct-server-return-mode as well as ping/udp/tcp and scripted health checks. You will find more information about this new feature in the case log of PSARC 2008/575.
The configuration is pretty straight-forward. To configure a loadbalancing on a group of four servers you have to use this commands:
I think as soon as this code is available in Opensolaris, i will try to marry it with the KSSL functionality. Would be nice, to use both functions to create an SSL-offloading loadbalancer :)
