Can you explain how the Round Robin load balancing method works?

The Round Robin load balancing method distributes incoming requests or tasks across a list of servers or resources sequentially and cyclically. Each new request is directed to the next server in the list, and after the last server, it returns to the first.

This is a simple and effective way to evenly distribute load without considering the current load of the servers. For example, if there are three servers A, B, and C, requests will be directed in the order: A, B, C, A, B, C, and so on.

The disadvantage of Round Robin is that it does not account for differences in performance or current load of the servers, so it may not be optimal in some cases.
