Deploying to multiple regions

We are now going to start creating a StackSet for a single account but in multiple regions. We will begin with the AWS Management Console.

Using the AWS console

Let’s start by deploying a StackSet with the core template in a single account (for example, our main account). We’ll begin with the AWS console. Follow these steps:

1. Once we log in to the console, we will go to CloudFormation - StackSets and click on Create StackSet. We will choose Template is ready, upload our core.yaml file (which you will find in the GitHub repository), and click Next. The template will be uploaded to Simple Storage Service (S3) automatically:

2. Now, we need to supply the StackSet name and parameters and hit Next:
