The Section Design your application with static subnets in multiple regions shows how to define multiple subnets for a network explicitly. However, users may not want to define the subnets explicitly. In such a case, the Cloud Create will auto-generate one subnet for each region dynamically as follows:
The following tutorial describes how to design an application with one (global) private network spanning in two regions of Google Cloud. Each region has one subnet and one compute connecting to the subnet (e.g., Compute connects to Subnet, Compute2 connects to Subnet2). The compute in the first region (e.g., Compute) has access to the internet.
Prerequisites
This section shows how to deploy your application on Google Cloud. You can create your application in multiple regions. Cloud Create can auto-generate one subnet for each region or you can design the subnets manually.
