Your company’s Azure subscription contains multiple resources. How can you identify which department is responsible for the cost of each resource?

Tags are key-value pairs that you can apply to Azure resources, resource groups, and subscriptions. They are crucial for organizing resources and managing costs. By adding a tag like "Department: Finance" or "Project: Q3Marketing" to resources, you can then use cost analysis tools to filter and group costs by these tags, effectively identifying which department or project is responsible for specific expenditures. Budgets are used to set spending limits and track actual versus forecasted costs, but they don't inherently identify the responsible department for individual resources. Alerts notify you of specific events or thresholds being met, such as exceeding a budget, but they don't provide the organizational context for cost allocation.
