Enforce data retention policies

Implementing data retention policies is crucial for managing and decommissioning resources effectively. It helps organizations to identify, manage, and delete unnecessary or orphaned resources in a timely manner, thus reducing waste and optimizing costs.

Best Practices

Implement Resource Tagging Strategy

• Establish a consistent tagging policy for resources, including tags for environment, owner, project, and cost center. This aids in tracking resource utilization and allocation. Ensure all team members are trained on the tagging process to maintain consistency.

Regularly Review and Audit Resource Usage

• Schedule regular audits of your resources to identify unused or underutilized ones. Utilize AWS Cost Explorer and AWS Budgets to monitor spending and project budgets, making it easier to identify resources that can be decommissioned.

Automate Resource Reporting and Alerts

• Implement automation tools to generate reports on resource usage and send alerts for resources that are idle for a specified period. Services like AWS Lambda can help automate this process efficiently, driving timely decommissioning.

Establish a Decommissioning Workflow

• Create a structured workflow for decommissioning resources that includes requesting decommissioning, approvals, and documenting reasons for decommissioning. This ensures change control and accountability throughout the lifecycle of your resources.

Leverage Resource Management Tools

• Use AWS Management tools like AWS Config to monitor configurations and relationships between resources over their lifetime. This assists in understanding dependencies and potential impacts before decommissioning resources.

Questions to ask your team

• Do you have a tagging strategy in place to identify resources by workload or function?
• How frequently do you review your resource inventory for unused or underutilized resources?
• Do you have automated processes to alert you about resources that are no longer needed?
• Is there a defined workflow for decommissioning resources once they are identified as unnecessary?
• Are you tracking the cost implications of your resources throughout their lifecycle?
• How do you ensure compliance with your change control procedures during decommissioning?
• Have you documented lessons learned from past resource decommissioning efforts?

Who should be doing this?

Cloud Administrator

• Implement and manage tagging strategies for resources.
• Monitor resource usage and identify unused resources for potential decommissioning.
• Coordinate with teams to ensure accurate tracking of resource lifecycles.

Finance Analyst

• Analyze cost reports and identify resources that contribute to wastage.
• Provide insights on resource utilization and recommend actions for cost reduction.
• Ensure budget alignment with resource usage and decommissioning plans.

Project Manager

• Oversee change control processes related to resource decommissioning.
• Facilitate communication between teams regarding resource lifecycle management.
• Ensure that all stakeholders are informed about resource decommissioning timelines and impacts.

DevOps Engineer

• Implement automation scripts to tag and track resources efficiently.
• Develop and maintain tools for monitoring resource health and lifecycle status.
• Collaborate with development teams to ensure resource decommissioning aligns with project timelines.

Compliance Officer

• Ensure decommissioning processes comply with governance and regulatory requirements.
• Review policies related to resource management and decommissioning.
• Audit resource usage and decommissioning activities for compliance reporting.

What evidence shows this is happening in your organization?

• Resource Tagging Policy: A formal document outlining the strategy for tagging AWS resources to track their purpose and associated workloads, helping to identify unused resources for decommissioning.
• Resource Lifecycle Management Checklist: A checklist used to ensure all steps in the resource lifecycle are followed, from creation to decommissioning, including methods for tracking and terminating unused resources.
• Monthly Resource Cost Report: A report generated monthly detailing all active AWS resources, their costs, and usage statistics to identify any resources that may be deemed unnecessary.
• AWS Resource Tracking Dashboard: An interactive dashboard using AWS Cost Explorer and tagging data to visually represent resource usage and associated costs over time, facilitating informed decisions on resource decommissioning.
• Decommissioning Strategy Document: A guide that outlines the procedures for safe and efficient decommissioning of AWS resources, including required approvals, tagging relevance, and communication strategies.
