amazon ec2 - How to setup Load balancing in EC2(wm where our services .war/.db are deployed into diff EC2 vm) in aws?

Question

How to setup Load balancing in EC2(wm where our services .war/.db are deployed into diff EC2 vm) in aws even after setting the Auto scaling & ELB managed service in AWS?

Answer 1

If you already set the Auto scaling group and ELB, maybe you're asking how to configure the routing algorithm of the load balancing? Default is round robin: https://docs.aws.amazon.com/elasticloadbalancing/latest/userguide/how-elastic-load-balancing-works.html

Or you're asking how to plug ec2 instances to the configured ELB, and then, as Asri said, put the ec2 instances in a target group, and attach the target group to the load balancer.
