AWS CloudFormation provides a way for users to model an entire AWS infrastructure in a text file, allowing for the infrastructure to be version-controlled, shared, and reused. Resources are the AWS components that are created, updated, or deleted when the CloudFormation stack is created, updated, or deleted. Parameters enable users to input custom values to a CloudFormation template, allowing for customization without modifying the template itself. Mappings define a set of key-value pairs that can be used to map input values to corresponding output values, making it possible to conditionally define properties and values based on the input parameters. Conditions enable users to define conditional statements within a CloudFormation template, allowing for the creation or modification of resources based on specific criteria. Outputs provide a way to export information about the created resources, making it possible to share this information between stacks or with external systems.
