HNSUS01-BP01 Decommission unused assets and consolidate redundant resources
Regularly audit your workload to identify and remove unused or redundant assets (for example, orphaned storage volumes, inactive EC2 instances, and outdated datasets). Consolidate overlapping resources (for example, duplicate reports and redundant databases) to eliminate waste.
Desired outcome: Reduced resource consumption and minimized environmental footprint by eliminating unnecessary infrastructure.
Level of risk exposed if this best practice is not established: Low
Benefits of establishing this best practice:
-
Frees up compute, storage, and network resources
-
Lowers energy consumption and costs
-
Simplifies architecture and improves maintainability
Implementation guidance
-
Identify underutilized resources. For example, you can achieve this using AWS Trusted Advisor Cost Optimization Checks
-
Use policies to automate deletion of unused assets. For example, you can achieve this using Amazon S3 Lifecycle Policies and Amazon Data Lifecycle Manager
