What is the primary function of the Google Cloud Resource Manager?

The primary function of the Google Cloud Resource Manager is to create, organize, and manage resources within a Google Cloud environment. This service provides an efficient hierarchy for organizing cloud resources, such as projects and folders, which allows for better management of permissions, policies, and overall cloud governance.

Resource Manager supports the effective management of resources by allowing users to apply IAM (Identity and Access Management) roles and permissions at different levels of the resource hierarchy. When you create a project, that project can hold various resources such as virtual machines, databases, and storage buckets, all managed under the same organizational structure. This modular approach makes it easier to manage and oversee cloud resources, ensuring that they align with the organization’s governance and compliance requirements.

In contrast, managing billing accounts focuses solely on financial aspects and does not encompass the organizational needs of resource management. Operational support and machine learning model development are separate functions that fall outside the scope of what Resource Manager is designed to accomplish. Therefore, the correct answer underscores the crucial role Resource Manager plays in the organizational aspect of Google Cloud.
