Haproxy compared to the use of LVS is much simpler, functional aspects are also very rich. Currently, Haproxy supports two main proxy modes: "TCP" is also 4 layers (mostly for mail servers, internal protocol communications Servers, etc.), and 7 tiers (HTTP). In 4-tier mode, Haproxy only forwards bidirectional traffic between the client and the server. In 7-tier m
