When you create a stack set, CloudFormation provisions a stack in each of the specified accounts and AWS Regions by using the supplied CloudFormation template and parameters. Stack sets let you manage a common set of AWS resources in a selection of accounts and AWS Regions in a single ...
In this article, we'll explore different secure methods to pass parameters in CloudFormation templates.

When you organize your AWS resources based on lifecycle and ownership, you might want to build a stack that uses resources that are in another stack. You can hard-code values or use input parameters to pass resource names and IDs. However, these methods can make templates difficult to reuse...
In the above example we have parameters that require input when the template is deployed. But we also have parameters that have a default value if no information is supplied for that parameter during deployment. OurInstanceTypeparameters has been set to only allow two inputs as acceptable. Which...
