You can choose to create an Automatic mode or Custom mode Virtual Private Cloud (VPC) network. Automatic mode networks create one subnet in each Google Cloud region automatically when you create the network. For Custom mode VPC networks, you have to create a network and then create subnets that you want within a region. You can create subnets when you create the network or you can add subnets later, but you cannot create instances in a region that has no subnet defined.
