What is the purpose of the IP Hash load balancing algorithm?

• A. To keep track of active server connections
• B. To route traffic based on the source IP of incoming requests
• C. To distribute load evenly across all servers
• D. To randomly select a server for each request

Answer: (B)

The IP Hash load balancing algorithm is designed specifically to route traffic based on the source IP address of incoming requests. This approach ensures that requests from the same client IP will consistently be directed to the same server. This is beneficial in scenarios where maintaining session persistence is important, as it enables a client to have a stable connection to a specific server without being redirected elsewhere on subsequent requests. This method helps in making traffic distribution more predictable and can enhance user experience, especially for applications that rely on session data. By using the source IP to determine the server, it also allows for a more targeted distribution of requests that can lead to optimizing resource usage across servers while reducing latency for returning visitors.
