Nginx's Httpupstreammodule provides simple load balancing for back-end (backend) servers. One of the simplest upstream is written as follows:Server backend1.example.com;Server backend2.example.com;server.backend3.example.com;Location/{Proxy_pass Http://backend;}1, back-end serverThe backend server can be set by upstream, which can be specified by IP address and port, domain name, UNIX socket (socket).

HAProxy is a proxy software that provides high availability, server load balancer, and TCP and HTTP applications, HAProxy is a completely free proxy solution that provides TCP and HTTP applications quickly and reliably with HAProxy. HAProxy is applicable to websites with large loads. these sites usually need session persistence or layer-7 processing. HAProxy supports tens of thousands of concurrent connecti

In Linux Streaming Server Load balancer, Layer7 identifies data streams (Connection Tracking ).1. the nf_conntrack that supports Layer7 does not really need to be destroyed. After that, you will feel that you need to change "data streams based on quintuple" to "data streams with fixed offsets based on application layer protocols, the sooner the better! Therefore, this person added several fields for nf_conn
