Load balancing common scheduling algorithm:RR (Round Robin). The RR algorithm is the simplest and most commonly used algorithm, that is, polling scheduling.LC (Least Connections). The LC algorithm, the minimum connection number algorithm, dynamically allocates the previous request based on the size of the node connections in the backend.SH (Source Hashing). SH is based on the source access scheduling algorithm, this algorithm has some session sessions

Haproxy although with Ha, but it does is load balanced. Haproxy is working on the four floor, which means that it can represent a wider range of services than Nginx, with a higher performance than nginx. Compared to LVS, configurable and relatively good, the need for the machine is not more than LVS. So haproxy is good to use under certain demand. For example, us
