Description: A reference to an output value in a CloudFormation stack is a mechanism that allows users to access the results of resources created in a CloudFormation template. These output values are useful for sharing information between different stacks or for providing details about the deployed infrastructure. Each stack can define one or more output values, which can be used to display relevant information, such as IP addresses, resource names, or any other data that may be useful for managing and operating the infrastructure. Output references are especially valuable in multi-stack environments, where different components of the infrastructure need to communicate with each other. By using these references, developers and administrators can build more complex and efficient architectures, facilitating integration and automation of processes in cloud environments.
