Build a Custom Network in Google Cloud Shell

Networks are the very backbone of cloud computing, and the ability to create a custom network is crucial. Custom networks allow custom subnets and firewall rules as well, so you can completely control access to your resources. In this hands-on lab, you’ll use the Google Cloud Shell to create a Cloud VPC network with two subnets, firewall rules that allow SSH ingress, and Compute Engine VM instances that connect to the subnets. Once the network and resources are established, you’ll test the connectivity of the networks via an SSH terminal.
