Implement Load Balancing on Compute Engine: Challenge Lab
#Create an instance template. Don't use the default machine type. Make sure you specify e2-medium as the machine type. #Create a managed instance group based on the template. #Create a firewall rule named as permit-tcp-rule-329 to allow traffic (80/tcp). #Create a health check. #Create a backend service and add your instance group as the backend to the backend service group with named port (http:80). #Create a URL map, and target the HTTP proxy to route the incoming requests to the default backend service. #Create a target HTTP proxy to route requests to your URL map #Create a forwarding rule.
