COST04-BP03 Decommission resources

Decommission resources triggered by events such as periodic audits, or changes in usage. Decommissioning is typically performed periodically, and is manual or automated.

Level of risk exposed if this best practice is not established: Medium

Implementation guidance

The frequency and effort to search for unused resources should reflect the potential savings, so an account with a small cost should be analyzed less frequently than an account with larger costs. Searches and decommission events can be triggered by state changes in the workload, such as a product going end of life or being replaced. Searches and decommission events may also be triggered by external events, such as changes in market conditions or product termination.

Implementation steps

  • Decommission resources: Using the decommissioning process, decommission each of the resources that have been identified as orphaned.
