Would Elasticache Redis endpoint be changed over time?

Question

AWS EC2 instances often have different host names and IPs over time. So in Nginx, I usually need to set a resolver to get the newest ip for current instance. Now my instance connects to a Elasticache Redis node endpoint. Would that endpoint change as well? Do I need a resolver for that redis node too?

Answer 1

As long as you use the endpoint (xxxxxx.amazonaws.com:6379) and not the IP to which the endpoint resolves to, you should be fine.

The endpoint only changes when the cluster gets recreated. The IP could change at any time
