A company has several Google Cloud projects, each managed by a different team. They want to ensure that each project's billing is tracked separately for chargeback purposes, but all projects should draw from a single, centralized organizational billing account. How should they configure their billing setup?
- ACreate a separate billing account for each project and link them to respective projects.
- BCreate a new organization for each project to isolate billing.
- CUse Cloud Monitoring to track costs per project and manually calculate chargebacks.
- DLink all projects to the single organizational billing account, and use labels on resources for chargeback.
Show answer & explanationAnswer & explanation
Correct answer: D. Link all projects to the single organizational billing account, and use labels on resources for chargeback.
Google Cloud allows multiple projects to be linked to a single billing account. While all costs accumulate in that one billing account, Google Cloud provides detailed billing reports that break down costs by project. Additionally, using labels on resources within each project can further refine cost tracking for chargeback purposes, all under a single central billing entity.
Why the other options are wrong
- A. Creating separate billing accounts would fulfill separate tracking but contradicts the requirement for a 'single, centralized organizational billing account'.
- B. Creating a new organization for each project is an extreme and unnecessary measure for billing isolation; it complicates management significantly.
- C. Cloud Monitoring tracks operational metrics, not billing. While billing data is available, manual calculation is inefficient and error-prone compared to native billing reports and labels.
Centralized Billing with Project Tracking
Google Cloud allows multiple projects to share a single billing account while providing detailed cost breakdowns by project in billing reports, often enhanced with resource labels for granular chargeback.
- One billing account can serve many projects.
- Billing reports show costs per project.
- Labels enable granular cost attribution for chargebacks.
Memory trick: Link all projects to ONE bill, then 'L'abel for 'L'earning costs.
