COST03-BP01: Configure billing and cost management tools

Configure and implement AWS billing and cost management tools to establish comprehensive visibility into your cloud spending. Proper configuration of these tools provides the foundation for effective cost monitoring, analysis, and optimization activities across your organization.

Implementation guidance

AWS provides a comprehensive suite of billing and cost management tools that, when properly configured, provide detailed visibility into your cloud spending patterns. These tools form the foundation of effective cost monitoring and enable data-driven optimization decisions.

Core Billing and Cost Management Tools

AWS Cost Explorer: Provides interactive cost analysis and visualization capabilities with pre-built reports and custom analysis options. Essential for understanding spending patterns and identifying trends.

AWS Cost and Usage Report (CUR): Delivers the most comprehensive and detailed cost and usage data available, suitable for advanced analytics and custom reporting requirements.

AWS Budgets: Enables creation of custom budgets with automated alerts and actions, providing proactive cost management capabilities.

AWS Cost Anomaly Detection: Uses machine learning to automatically identify unusual spending patterns and provides early warning of potential cost issues.

Tool Configuration Strategy

Comprehensive Coverage: Configure tools to monitor all AWS accounts, services, and resources within your organization to ensure complete cost visibility.

Appropriate Granularity: Set up monitoring at the right level of detail for different use cases, from high-level executive summaries to detailed resource-level analysis.

Automated Processing: Configure automated data collection, processing, and reporting to reduce manual effort and ensure timely cost insights.

Integration Ready: Set up tools with appropriate APIs, data exports, and integration capabilities to support broader cost management workflows.

Configuration Best Practices

Centralized Management: Use AWS Organizations to centrally manage billing and cost tools across all accounts in your organization.

Role-Based Access: Configure appropriate access controls to ensure different stakeholders have access to relevant cost information without compromising security.

Data Retention: Configure appropriate data retention policies to maintain historical cost data for trend analysis and forecasting.

Export and Integration: Set up automated data exports and integrations to support advanced analytics and business intelligence requirements.

AWS Services to Consider

AWS Cost Explorer

Configure Cost Explorer with custom filters, groupings, and saved reports. Set up regular report generation and sharing for different stakeholder groups.

AWS Cost and Usage Report (CUR)

Configure CUR to deliver detailed cost data to S3 buckets. Set up appropriate data formats, compression, and delivery schedules for your analytics needs.

AWS Budgets

Create comprehensive budget structures covering different organizational dimensions. Configure automated alerts and actions for proactive cost management.

AWS Cost Anomaly Detection

Configure anomaly detection monitors for different cost dimensions. Set up appropriate alert thresholds and notification channels.

AWS Organizations

Configure consolidated billing and organizational structure to support centralized cost management across multiple accounts.

AWS Identity and Access Management (IAM)

Configure appropriate permissions and roles for cost management tools. Ensure secure access to billing information based on organizational needs.

Amazon S3

Configure S3 buckets for storing cost and usage reports. Set up appropriate lifecycle policies and access controls for cost data storage.

AWS CloudFormation

Use CloudFormation to automate the deployment and configuration of cost management tools across multiple accounts and regions.
