How can you organize Google Cloud projects based on independent business units while maintaining IAM permissions?

Creating an organization node and assigning folders is an effective way to organize Google Cloud projects based on independent business units while maintaining IAM permissions. This approach allows for a hierarchical structure that mirrors the organization’s business units, making it easier to manage and apply IAM roles and permissions at different levels.

An organization node serves as the root of the Google Cloud resource hierarchy, and by using folders, you can group projects according to the distinct business units or functionalities they represent. Each folder can have its own IAM policies, allowing you to control access at a granular level. This means that you can assign different permissions to projects under different folders, aligning the IAM policies with the specific needs of each business unit.

This method also helps in maintaining visibility, security, and compliance as organizational policies can be applied consistently across folders, ensuring that business units can operate independently while still adhering to the company-wide security framework. By using this structured approach, managing permissions becomes more efficient, minimizing the risk of unauthorized access and ensuring that each business unit has the appropriate level of control over its resources.
