 # Cleaning Up
 
-In this lab you will delete the compute resources created during this tutorial.

-## Compute Instances
-
-Delete the controller and worker compute instances:
+In this lab you will delete the compute resources created during this tutorial. Everything you created belongs to the `kubernetes-the-hard-way` resource group, so cleaning everything up is as simple as deleteing the resource group:
 
 ```
-gcloud -q compute instances delete \
-  controller-0 controller-1 controller-2 \
-  worker-0 worker-1 worker-2
+az group delete --name kubernetes-the-hard-way --no-wait --yes
 ```
 
-## Networking
-
-Delete the external load balancer network resources:
+This operation may take a while, periodically check to make sure everything was deleted:
 
 ```
-{
-  gcloud -q compute forwarding-rules delete kubernetes-forwarding-rule \
-    --region $(gcloud config get-value compute/region)
-
-  gcloud -q compute target-pools delete kubernetes-target-pool
-
-  gcloud -q compute http-health-checks delete kubernetes
-
-  gcloud -q compute addresses delete kubernetes-the-hard-way
-}
+az group exists --name kubernetes-the-hard-way
 ```
 
-Delete the `kubernetes-the-hard-way` firewall rules:
 
-```
-gcloud -q compute firewall-rules delete \
-  kubernetes-the-hard-way-allow-nginx-service \
-  kubernetes-the-hard-way-allow-internal \
-  kubernetes-the-hard-way-allow-external \
-  kubernetes-the-hard-way-allow-health-check
-```
-
-Delete the `kubernetes-the-hard-way` network VPC:
-
-```
-{
-  gcloud -q compute routes delete \
-    kubernetes-route-10-200-0-0-24 \
-    kubernetes-route-10-200-1-0-24 \
-    kubernetes-route-10-200-2-0-24
-
-  gcloud -q compute networks subnets delete kubernetes

-  gcloud -q compute networks delete kubernetes-the-hard-way
