Load Balancer Stickiness

It is possible to implement stickiness so that the same client is always redirected to the same instance behind a load balancer

This works for Classic Load Balancers & Application Load Balaners

The "cookie" used for stickiness has an expiration date you control

Use case: make sure the user doesn't lose his session data

-> without this when you talk to another server, you will lose your state

Enabling stickiness may bring imbalance to the load over the backend EC2 instances
