How it works...
In step 1, we have created a firewall rule called allow-http to allow incoming requests to TCP port 80 and 8080. Since our instance app is tagged with http, it can accept incoming traffic to port 80 and 8080.
In step 2, we have allowed all the instances with IP 10.0.0.0/16, which is a private IP address range. Along with connection parameters and the source IP address CIDR, we have defined the network name and subnet name. We have allowed all TCP connections. If we want to restrict it to a port or a range of ports, then we can use tcp:80 or tcp:4000-5000 respectively.
