What does REF mean in CloudFormation?

The intrinsic function Ref returns the value of the specified parameter or resource. When you specify a parameter’s logical name, it returns the value of the parameter.

What is FN in CloudFormation?

The intrinsic function Fn::Sub substitutes variables in an input string with values that you specify. In your templates, you can use this function to construct commands or outputs that include values that aren’t available until you create or update a stack.

What is outputs in CloudFormation?

All. The optional Outputs section declares output values that you can import into other stacks (to create cross-stack references), return in response (to describe stack calls), or view on the AWS CloudFormation console. For example, you can output the S3 bucket name for a stack to make the bucket easier to find.

Does CloudFormation create S3 bucket?

If you specify a template file stored locally, CloudFormation uploads it to an S3 bucket in your AWS account. CloudFormation creates a bucket for each region in which you upload a template file. The buckets are accessible to anyone with Amazon Simple Storage Service (Amazon S3) permissions in your AWS account.

Does CloudFormation track state?

CloudFormation can use change sets to create an overview of how proposed stack changes in the most recently submitted stack template will impact your resources. This is only possible for resources created with CloudFormation. CloudFormation does not offer a way to check the actual state of the infrastructure.

What language does CloudFormation use?

An AWS CloudFormation template is a formatted text file in JSON or YAML language that describes your AWS infrastructure.
