Apache HTTPD mod_proxy_balancer
Apache HTTPD mod_proxy_balancer is an Apache HTTPD module that provides Apache HTTPD load balancing capabilities for the Apache HTTP Server (HTTPD). It allows the server to distribute incoming requests across multiple backend servers, helping to distribute the workload evenly and improve performance, scalability, and fault tolerance. Mod_proxy_balancer supports various load balancing algorithms, including round-robin, least connections, and weighted load balancing, enabling administrators to customize the distribution of requests based on factors such as server capacity, response time, and traffic patterns. This module also provides features such as session persistence, health checking, and dynamic reconfiguration, allowing the load balancer to adapt to changes in backend server availability and performance. Mod_proxy_balancer is commonly used in conjunction with other proxy modules like mod_proxy_http and mod_proxy_ajp to build resilient and high-performance proxy setups for web applications and services. s://httpd.apache.org/docs/2.4/mod/mod_proxy_balancer.html
