SUS05-BP01 Use the minimum amount of hardware to meet your needs - AWS Well-Architected Framework

SUS05-BP01 Use the minimum amount of hardware to meet your needs

Use the minimum amount of hardware for your workload to efficiently meet your business needs.

Common anti-patterns:

  • You do not monitor resource utilization.

  • You have resources with a low utilization level in your architecture.

  • You do not review the utilization of static hardware to determine if it should be resized.

  • You do not set hardware utilization goals for your compute infrastructure based on business KPIs.

Benefits of establishing this best practice: Rightsizing your cloud resources helps to reduce a workload’s environmental impact, save money, and maintain performance benchmarks.

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

Implementation guidance

Optimally select the total number of hardware required for your workload to improve its overall efficiency. The AWS Cloud provides the flexibility to expand or reduce the number of resources dynamically through a variety of mechanisms, such as AWS Auto Scaling, and meet changes in demand. It also provides APIs and SDKs that allow resources to be modified with minimal effort. Use these capabilities to make frequent changes to your workload implementations. Additionally, use rightsizing guidelines from AWS tools to efficiently operate your cloud resource and meet your business needs.
