Loadbalancer-less clusters on Linux

Flavio Villanustre writes “When you think of implementing virtual servers, either because you need to cope with a higher load or to provide enhanced reliability, you face a new problem: how to avoid making the load balancers (or directors) the bottleneck and the single point of failure for the whole architecture. And there is an associated cost with traditional load balancing as you also need to add one (or better two for redundancy) more servers for the load balancer function itself.”
