What tool can an organization use for the governance of its Azure resources to ensure optimal resource utilization and cost management?

Azure Policy is an essential tool for governance within Azure that helps organizations enforce specific rules and effects over their resources. It enables a company to define and manage policies that govern how resources are created and maintained. By doing so, organizations can ensure compliance with internal requirements and external regulations. This governance capability directly contributes to optimal resource utilization and cost management by allowing policies that restrict or allow certain types of resources, regions, and resource configurations.

For instance, an organization might implement policies that limit the types of virtual machines that can be created, specify allowed locations for resource deployment, or ensure that certain resource tags are applied, which can help in accurately tracking and managing costs. This level of control helps to prevent resource over-provisioning or unintended configurations that can lead to financial inefficiencies.

In contrast, while Azure Resource Manager is important for resource management, it does not provide the governance framework that Azure Policy does. Azure Monitor focuses on collecting and analyzing telemetry data for monitoring performance, while Azure Security Center is centered on security management and threat protection rather than resource governance. Therefore, Azure Policy stands out as the most suitable choice for ensuring governance that optimizes resource use and manages costs effectively within an Azure environment.
