Balance the traffic across to all nodes of our applications.

▪ Spread the traffic across a cluster of servers to improve

responsiveness and availability.

▪ Load Balancer sits between the client and the server.

▪ Load Balancer is accepting incoming network and

application traffic.

▪ Distributing the traffic across multiple backend servers using

different algorithms.

▪ Load Balancers should be fault tolerance and improves

availability.

▪ Mostly uses the consistent hashing algorithms. Consistent

hashing is an algorithms for dividing up data between

multiple machines.

▪ It solves the horizontal scalability problems. Don’t have to rearrange all the keys.
