first_byte – Time to receive the first byte of data.connect – Time to connect to the upstream server.The method used to calculate lowest average latency depends on which of the following parameters is included on the least_time directive: Least Time (NGINX Plus only) – NGINX Plus selects the server with the lowest average latency and the least number of active connections. Least Connections – NGINX selects the server with the smaller number of current active connections. Because it is the default method, there is no round‑robin directive simply create an upstream context and add server directives as described in the previous step. Round Robin – By default, NGINX uses the Round Robin algorithm to load balance traffic, directing it sequentially to the servers in the configured upstream group. You can specify one of the following methods: Open the NGINX configuration file and perform the following steps:Ĭonfigure the load‑balancing method used by the upstream group. Upstream servers, each running the same instance of the application, database, or serviceįirst, you will need to configure reverse proxy so that NGINX Plus or NGINX Open Source can forward TCP connections or UDP datagrams from clients to an upstream group or a proxied server.An application, database, or service that communicates over TCP or UDP.Latest NGINX Plus (no extra build steps required) or latest NGINX Open Source built with the -with-stream configuration flag.To load balance HTTP traffic, refer to the HTTP Load Balancing article. UDP (User Datagram Protocol) is the protocol for many popular non-transactional applications, such as DNS, syslog, and RADIUS. In NGINX Plus Release 9 and later, NGINX Plus can proxy and load balance UDP traffic. TCP is the protocol for many popular applications and services, such as LDAP, MySQL, and RTMP. In NGINX Plus Release 5 and later, NGINX Plus can proxy and load balance Transmission Control Protocol) (TCP) traffic. Load balancing refers to efficiently distributing network traffic across multiple backend servers. This chapter describes how to use NGINX Plus and NGINX Open Source to proxy and load balance TCP and UDP traffic.
