Managed instance group contains identical instnaces, created from an instance template. Supports auto scaling, auto healing, rolling updates, load balancing. VM instances are stateless and disks are deleted on VM recreation. It is possible for load balancer to send traffic to instance group through a named port. Configure autoscaling on and autoscaling policy. Auto scaling policy directs when to auto-scale, based on CPU utlization, HTTP load balancing utilization, Stack driver metric, or combination of the above. It is possible to specify maximum number of instances that can be in instance group. Enable auto healing through healhcheck configuration. Instance group while running, you can add/remove labels. You can do modifications just as you can do with an instance running. With instance group you can have rolling update, rolling restart/replace actions. When performing rolling update, perform canary deployment, and make sure that no rollback is needed. If rollback is needed, t
