Only two health-check mechanisms (ICMP ping and TCP socket open)
No higher-layer persistence mechanisms (Sticky IP only)
No “sorry-server” mechanism if all servers in group are not responding
No “round robin with persistence” mechanism
No “weighted round robin” mechanism
No method for detecting if resource is strained
