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.

AWS Services to Consider

AWS Config

Automatically discover and track resource configurations and changes. Use Config to maintain comprehensive resource inventory and track configuration drift.

AWS Systems Manager Inventory

Collect detailed information about resources and their configurations. Use Systems Manager to gather metadata and track resource attributes.

AWS Resource Groups

Organize resources into logical groups for tracking and management. Use resource groups to track related resources and their lifecycle status.

Amazon CloudWatch

Monitor resource utilization and performance metrics. Use CloudWatch to track usage patterns and identify decommissioning candidates.

AWS CloudTrail

Track resource creation, modification, and access activities. Use CloudTrail to understand resource usage patterns and ownership.

Amazon DynamoDB

Store resource tracking data and metadata. Use DynamoDB for fast access to resource information and lifecycle status.
