Editing Load balancer (Networking)

[[wikipedia:Load balancing (computing)|Load balancing]] across multiple application instances is a commonly used technique for optimizing resource utilization, maximizing throughput, reducing latency, and ensuring fault‑tolerant configurations.



Load balancing in [[Nginx]] is configured using <code>[[upstream]]</code> directive.<ref>https://docs.nginx.com/nginx/admin-guide/load-balancer/http-load-balancer/#overview</ref>

Network load balancer can provide service for different protocols, such as [[TCP]], [[UDP]], [[HTTP]] or [[HTTPS]].



Typical options:
* [[TCP]], [[UDP]], [[HTTP]], [[HTTPS]]
* Load Balancing algorithm: [[WRR]], [[weighted least connection]], [[source IP hash]]
* [[Sticky]] [[session]]
