What should a multinational company create to manage multiple subscriptions and apply consistent governance across them?

Management groups are containers that help you manage access, policy, and compliance across multiple Azure subscriptions. They provide a level of organization above subscriptions, allowing you to apply governance policies consistently to all subscriptions within a management group. This is crucial for multinational companies needing to enforce corporate standards across diverse organizational structures. Resource groups are for organizing resources within a subscription, not across multiple subscriptions. Azure Blueprints help define repeatable sets of Azure resources that adhere to organizational standards, but management groups provide the hierarchical structure for applying these blueprints or other policies at scale. Azure Cost Management is a tool for tracking and optimizing cloud spending, not for organizational hierarchy or governance enforcement.
