title: What is the difference between Load Balancer cookies stickiness and ElastiCache for storing user session?
body: <p>I have heard about two approaches to store user session in Amazon AWS. One approach is to use cookies stickiness with Load Balancer and the other is to store user session to ElastiCache. What are the advantages and disadvantages if I want to use the EC2 Load Balancer as well as ElastiCache? Where should I store the user session?</p>
