Migrating services from a NLB load balancer with an instance group as a target to an L7 ALB load balancer

In this tutorial, you will learn how to integrate a NLB load balancer with a group of VMs. This VM group tracks the number of VMs in the group and changes the composition of the load balancer's target group as needed.
