Round-Robin: This is the simplest method that routes requests across all the instances sequentially

Least Connections: This is a method in which the request goes to the instance that has the fewest number of connections at the time

Weighted Round-Robin: This is an algorithm that assigns weight to each instance and forwards the connection according to this weight

IP Hash: This is a method that generates a unique hash key from the source IP address and determines which instance receives the request
