Explanation:
Exporting Cloud Billing data to BigQuery is the most effective solution for daily and monthly cost analysis across multiple GCP projects because:
- Comprehensive Analysis: BigQuery allows you to perform complex queries, aggregations, and analysis on billing data across all projects.
- Automation: Once set up, data is automatically exported daily, providing regular cost insights.
- Cross-Project Analysis: You can easily analyze costs across multiple projects in a single query.
- Historical Data: BigQuery stores historical billing data for trend analysis.
- Custom Reporting: You can create custom dashboards and reports using tools like Data Studio or Looker.
Why other options are not optimal:
- A) Use billing reports in the Console: While useful, Console reports have limitations for complex cross-project analysis and automated daily/monthly reporting.
- C) Download invoices manually: This is inefficient, not automated, and doesn't provide the detailed analysis capabilities needed.
- D) Use gcloud billing list: This command provides basic billing information but lacks the comprehensive analysis capabilities needed for detailed daily/monthly cost analysis across multiple projects.
