LOAD BALANCER ALGORITHMS

#AWS

In NGINX or any proxy server, various load balancing algorithms can be used to distribute incoming requests to backend hosts. These algorithms determine how traffic is routed to different servers, helping to balance the load efficiently. One common approach is the least_conn algorithm, which sends requests to the server with the least number of active connections, ensuring that no single server gets overwhelmed. Other algorithms such as round_robin, which sends requests in a circular manner to all servers, or ip_hash, which routes requests from a specific client IP to the same backend server, are also frequently used depending on the use case. The choice of algorithm is crucial for optimizing performance and ensuring high availability, as it can impact how well the proxy server handles traffic spikes and distributes load across the backend infrastructure.
