Resource Efficiency & Optimisation

Resource Sizing

Summary

Provisioned compute and storage capacity matches measured peak demand plus the headroom required for scaling, reliability, and performance.

Standards

  1. A workload's compute or storage usage MUST be monitored against its provisioned capacity. std-cost-resource-sizing-01
  2. A workload MUST define the capacity headroom required for scaling, reliability, and performance. std-cost-resource-sizing-02
  3. Provisioned compute or storage capacity SHOULD NOT exceed a workload's measured peak demand plus its defined headroom. std-cost-resource-sizing-03
  4. Provisioned compute or storage capacity SHOULD be adjusted when it no longer matches a workload's measured peak demand plus its defined headroom. std-cost-resource-sizing-04

Implements These Principles

Resource Lifecycle

Summary

Compute and storage resources are decommissioned when they no longer serve a workload or retention requirement, avoiding unnecessary cost.

Standards

  1. Each provisioned compute or storage resource MUST have an identified owner and serve a current workload or retention requirement. std-cost-resource-lifecycle-01
  2. A compute or storage resource MUST be decommissioned when it no longer serves a workload or retention requirement. std-cost-resource-lifecycle-02

Implements These Principles

Telemetry Volume

Summary

A service collects only the telemetry needed to support incident response and meet compliance requirements.

Standards

  1. A service SHOULD define the telemetry needed to support incident response and meet compliance requirements. std-cost-telemetry-volume-01
  2. A service SHOULD NOT collect or retain telemetry beyond those needs. std-cost-telemetry-volume-02

Implements These Principles

Storage Tiering

Summary

Stored data uses the lowest-cost storage tier that meets its access and compliance requirements.

Standards

  1. A service SHOULD define the access and compliance requirements for its stored data. std-cost-storage-tiering-01
  2. Stored data SHOULD use the lowest-cost storage tier that meets its defined access and compliance requirements. std-cost-storage-tiering-02

Implements These Principles
