COST04-BP01: Track resources over their lifetime
Implement comprehensive tracking of resources from creation to decommissioning to ensure visibility into resource lifecycle and enable proactive management. Effective tracking prevents resource sprawl and enables timely identification of decommissioning opportunities.
Implementation guidance
Resource lifecycle tracking provides the foundation for effective decommissioning by maintaining comprehensive visibility into all resources, their usage patterns, dependencies, and business context throughout their entire lifecycle.
Tracking Framework Principles
Comprehensive Coverage: Track all resources across all accounts, regions, and services to ensure no resources are overlooked during decommissioning activities.
Lifecycle Visibility: Maintain visibility into resource status from creation through active use to eventual decommissioning.
Business Context: Include business context such as project association, ownership, and purpose to enable informed decommissioning decisions.
Automated Discovery: Use automated tools to continuously discover and catalog resources to maintain accurate and up-to-date inventory.
Resource Tracking Components
Resource Inventory: Comprehensive catalog of all resources with metadata including creation date, owner, purpose, and current status.
Usage Monitoring: Continuous monitoring of resource utilization patterns to identify underutilized or unused resources.
Dependency Mapping: Documentation of resource relationships and dependencies to understand impact of decommissioning decisions.
Cost Attribution: Association of costs with resources to enable cost-based decommissioning prioritization.
