Mastering 8 Essential Load Balancing Algorithms

[ Eight load balancing algorithms optimize server resource allocation. Round Robin cycles through servers sequentially; Least Connections sends requests to the least busy server. Weighted variations prioritize servers based on capacity. IP Hash ensures session persistence by directing requests based on IP address. Least Response Time minimizes latency, while Random distributes requests randomly. Least Bandwidth and Weighted Least Connections further refine resource allocation by considering bandwidth usage and weighted connection counts, respectively. These algorithms are crucial for efficient system design and prevent server overload. ]

Round Robin It assigns a request to the first server, then moves to the second, third, and so on, and after reaching the last server, it starts again at the first.
Least Connections The Least Connections algorithm directs incoming requests to the server with the lowest number of active connections.
Weighted Round Robin It assigns different weights to servers based on their capacities and distributes requests proportionally to these weights.
Weighted Least Connections The Weighted Least Connections algorithm combines the Least Connections and Weighted Round Robin algorithms. It directs incoming requests to the server with the lowest ratio of active connections to assigned weight.
IP Hash The IP Hash algorithm determines the server to which a request should be sent based on the source and/or destination IP address. This method maintains session persistence, ensuring that requests from a specific user are directed to the same server.
Least Response Time It directs incoming requests to the server with the lowest response time and the fewest active connections.
Random It directs incoming requests to a randomly selected server from the available pool.
Least Bandwidth It directs incoming requests to the server currently utilizing the least amount of bandwidth. This approach helps to ensure that servers are not overwhelmed by network traffic.
