Which tool would you recommend for identifying unused resources in an Azure subscription?

The recommendation of Azure Advisor for identifying unused resources in an Azure subscription is grounded in its primary function of providing personalized best practices and recommendations to enhance your Azure environment. Azure Advisor analyzes your usage patterns, configuration, and other operational data to identify areas where you can optimize your resources. This includes highlighting underutilized or over-provisioned resources, enabling organizations to make informed decisions about resource management and cost reduction.

By providing actionable insights regarding idle resources, Azure Advisor assists users in optimizing their cloud spend, ensuring that they are only utilizing resources that provide value. This tailored advice not only helps in managing costs but also contributes to improving overall resource efficiency within the Azure subscription.

Other tools mentioned serve different primary purposes. For instance, Azure Security Center primarily focuses on security assessments and recommendations rather than resource efficiency. Azure Policy is used to enforce compliance and implement governance rules, and while it can help track resources, it does not specifically target identifying unused resources. Azure Cost Management is focused on budget tracking and cost analysis but does not actively highlight unused resources. Therefore, Azure Advisor is the most effective choice for this particular need.
