Consistent Billing Reports Across AI Departments with GCP Organizations

Question

Pulumi · Accepted Answer

To ensure consistent billing reports across AI departments using Google Cloud Platform (GCP), you would want to organize your resources effectively and set up policies that enforce consistent billing practices across different projects and folders within an organization. Using Pulumi's infrastructure as code approach, you and your team can automate the creation and management of such resources and policies.

Here is what we will do with Pulumi:

We will define an organization-level IAM policy to ensure access control is consistent across the entire organization.
Projects will be created for different AI departments, ensuring each one has the required settings, and they will be linked to a shared billing account for consistency.
We will implement organization policies, focusing on billing, to manage how resources are used across the organization, providing consistent reporting.
We will also set up folders, which can be used to group projects by department, with each folder inheriting policies from the organization level.

Below is an example Pulumi program that illustrates how to adopt the above approach:

import pulumi
import pulumi_gcp as gcp

# Ensure you configure the GCP provider with the appropriate credentials
gcp.provider.Provider("my-provider",
                      region="us-central1")  # replace with your GCP region

# Define GCP Organization ID and Billing Account ID
# Replace '<org_id>' and '<billing_account_id>' with your actual GCP organization and billing account IDs.
organization_id = '<org_id>'
billing_account_id = '<billing_account_id>'

# 1. Define IAM Policy for the Organization
# This example grants the 'Billing Account Viewer' role at an organization level
org_iam_policy = gcp.organizations.IAMPolicy("org-iam-policy",
                                             orgId=organization_id,
                                             policyData=pulumi.Output.all(organization_id).apply(
                                                 lambda args: f"""
{
"bindings": [
    {
    "role": "roles/billing.viewer",
    "members": [
        "user:billing@example.com"  # Replace with the email of your billing administrator
    ]
    }
]
}
"""
                                             ))

# 2. Create Projects for AI Departments
# Ensure each department's project is linked to the same billing account
ai_dept_project = gcp.organizations.Project("ai-dept-project",
                                            name="ai-department",
                                            projectId="ai-department-project",
                                            billingAccount=billing_account_id,
                                            orgId=organization_id)

# 3. Enforce Billing Constraints at the Organization Level
# This example enforces a policy that restricts billing accounts to a list of allowed values.
org_billing_policy = gcp.organizations.Policy("org-billing-policy",
                                              orgId=organization_id,
                                              constraint="constraints/billing.allowedBillingAccounts",
                                              listPolicy=gcp.organizations.PolicyListPolicyArgs(
                                                  allowed_values=[billing_account_id]
                                              ))

# 4. Create Folders for AI Departments
# Folders can help segment resources for consistent policy application
ai_dept_folder = gcp.organizations.Folder("ai-dept-folder",
                                          displayName="AI Department",
                                          parent=f"organizations/{organization_id}")

# Example: Export the project ID for reference in other processes or scripts
pulumi.export("ai_department_project_id", ai_dept_project.projectId)

This program sets up a basic structure for managing consistent billing and access policies across AI departments in a GCP organization. You'll need to fill in your GCP organization's specific details, like the organization ID and billing account ID.

Remember, the specific roles, policies, and project configurations may differ based on your organization's needs. Adjust the roles, permissions, and policies accordingly. Always ensure that operations such as these are performed by a user with sufficient permissions within GCP to manage organization-level resources and policies.

The pulumi.export statement at the end is used to output the project ID, which can be useful if you wish to reference this project in other Pulumi programs or scripts.
