COST04-BP04: Decommission resources automatically
Implement automated systems to identify and decommission resources based on predefined criteria and policies. Automation reduces manual effort, ensures consistency, and enables proactive cost management through systematic resource cleanup.
Implementation guidance
Automated decommissioning enables organizations to systematically identify and remove unused or underutilized resources without manual intervention, reducing costs and operational overhead while maintaining safety and compliance requirements.
Automation Principles
Policy-Driven: Use clearly defined policies and criteria to determine when resources should be automatically decommissioned.
Safety First: Implement comprehensive safety checks and validation to prevent accidental decommissioning of critical resources.
Gradual Implementation: Start with low-risk scenarios and gradually expand automation to more complex use cases.
Monitoring and Alerting: Maintain visibility into automated decommissioning activities with comprehensive logging and alerting.
Automation Components
Resource Discovery: Automated identification of resources that meet decommissioning criteria.
Policy Evaluation: Systematic evaluation of resources against decommissioning policies and rules.
Safety Validation: Automated checks to ensure resources can be safely decommissioned.
Execution Engine: Automated execution of decommissioning procedures with proper error handling.
