What is the difference between a parameter & an output in a CloudFormation template?

Question

Mahesh B · Accepted Answer

Parameters in a CloudFormation template allow users to input values at runtime for customizing resource configurations, while outputs provide important information about the created resources after stack deployment. Parameters are used during stack creation, whereas outputs are accessible post-deployment for reference and integration with other services Examples: Parameter: Accepting a VPC ID or instance type as input to customize the resources being created. Output: Returning the public IP address of an EC2 instance or the ARN of an S3 bucket created by the stack.
