What are the advantages of using a load balancer in a system?

The load balancer provides the following advantages:

• Traffic distribution — evenly distributes incoming requests among multiple servers or instances, increasing performance.

• Fault tolerance — when one server fails, the load balancer redirects traffic to available nodes, ensuring continuous operation.

• Scalability — allows easy addition of new servers to the pool to handle increasing load.

• Resource optimization — prevents overload of individual servers, improving overall resource utilization.

• Support for various distribution algorithms — such as round-robin, least connections, IP-hash, etc., enabling tailored load balancing for specific tasks.
