Which AWS feature allows identifying and managing resources using words or phrases?

The feature that allows identifying and managing resources using words or phrases is tags. Tags are key-value pairs assigned to AWS resources, enabling better organization, management, and tracking of those resources. By applying tags, users can categorize resources according to specific criteria, such as project, environment, or owner, making it easier to search for and manage resources across various AWS services.

Tags also play a crucial role in cost allocation by providing visibility into resource usage and expenses associated with specific projects or departments. This helps organizations optimize their cloud spending and improve resource utilization.

In contrast, resource groups, service limits, and ARNs serve different purposes. Resource groups are collections of AWS resources that share a common tag, primarily used for management convenience but not for the identification or categorization based on words or phrases alone. Service limits refer to the maximum resource usage or quotas imposed by AWS, and ARNs (Amazon Resource Names) are unique identifiers for AWS resources that facilitate their access and management but don’t inherently provide descriptive labeling or organization.
