NGINX as Load Balancer

Web server plus balancer

NGINX started as a web server but excels at load balancing. It's often the first choice when you need both serving and balancing.

upstream backend {
    least_conn;
    server 192.168.1.10:8080;
    server 192.168.1.11:8080;
}

server {
    listen 80;
    location / {
        proxy_pass http://backend;
    }
}

NGINX supports round-robin, least connections, IP hash, and weighted distribution. NGINX Plus (commercial) adds health checks, session persistence, and dynamic reconfiguration.
