What do you mean by a target group in AWS Load Balancing?

In AWS, a target group is a group of resources that can receive traffic from an Application Load Balancer or a Network Load Balancer. Target groups are used to route traffic to specific resources based on the rules and settings defined in the load balancer. They can be used to perform health checks on the resources in the group, and only route traffic to healthy resources. They are associated with a load balancer and can be configured to route traffic to different resources based on the incoming request's protocol and host/path.
