Description: The ‘Output Group Name’ refers to a set of output values that can be defined in an AWS CloudFormation stack. These output values are useful for providing information about the resources created by the stack, such as IP addresses, resource names, or any other relevant data that may be necessary for managing and operating the infrastructure. By defining an output group, users can easily access this information without needing to manually search in the AWS console or other services. This enhances efficiency and automation in cloud resource management, allowing developers and system administrators to integrate these values into other processes or management tools. Additionally, output values can be used in other CloudFormation stacks, facilitating the creation of more complex and modular architectures. In summary, the ‘Output Group Name’ is a key feature that allows AWS CloudFormation users to effectively obtain and utilize critical information about their resources.
