Define 'cloud resource tagging'.

Cloud resource tagging involves assigning attributes or labels to cloud resources, which significantly enhances management and cost tracking capabilities. By organizing resources with specific tags, such as project names, department identifiers, or cost center codes, organizations can gain better visibility into their cloud resource usage. This practice facilitates easier tracking of expenses and allocation of costs to different teams or projects, resulting in improved budgeting and financial oversight.

In addition, tagging allows for more efficient resource management by enabling filtering and searching based on these tags. For instance, if an organization wants to quickly identify all resources related to a specific project or department, tags make this process straightforward. It aids in operational tasks such as reporting, governance, and compliance by providing contextual information about the resources used.

The other options presented do not align with the definition of cloud resource tagging. Creating backups, securing resources, and deleting unused resources are all vital cloud management practices, but they do not relate to the process of tagging or assigning attributes to the resources themselves.
