COST03: How do you monitor usage and cost?

Establish cost monitoring and usage tracking to gain visibility into your cloud spending patterns. Effective monitoring enables you to identify cost drivers, detect anomalies, optimize resource usage, and make informed decisions about your cloud investments. This visibility is essential for maintaining cost control and achieving your financial objectives.

Best Practices

This question includes the following best practices:

Key Concepts

Cost Monitoring Principles

Comprehensive Visibility: Implement monitoring that covers all aspects of your cloud usage and costs, including direct costs, indirect costs, and opportunity costs.

Real-Time Awareness: Establish near real-time monitoring capabilities that enable quick detection of cost anomalies and usage changes.

Granular Attribution: Ensure costs can be attributed to specific business units, projects, applications, or other relevant organizational dimensions.

Actionable Insights: Focus on monitoring that provides actionable insights rather than just data collection, enabling informed decision-making and optimization actions.

Monitoring Framework Components

Data Collection: Systematic collection of cost and usage data from all relevant sources, including AWS services, third-party tools, and business systems.

Data Processing: Transformation and enrichment of raw cost data to make it meaningful and actionable for different stakeholders and use cases.

Analysis and Reporting: Regular analysis of cost trends, patterns, and anomalies with appropriate reporting for different audiences and purposes.

Alerting and Notification: Proactive alerting systems that notify relevant stakeholders when costs exceed thresholds or unusual patterns are detected.

Cost Attribution Strategies

Hierarchical Attribution: Organize cost attribution in a hierarchical structure that reflects your organizational structure and business model.

Multi-Dimensional Tagging: Use comprehensive tagging strategies that enable cost attribution across multiple dimensions simultaneously.

Dynamic Allocation: Implement dynamic cost allocation methods that can adapt to changing business structures and requirements.

Shared Cost Allocation: Develop methodologies for allocating shared costs fairly and transparently across business units and projects.
