COST07-BP05 - Perform pricing model analysis at the management account level
Implementation guidance
Perform pricing model analysis at the management account level so that commitment-based discounts (Savings Plans and Reserved Instances) are evaluated and purchased across the whole AWS Organization rather than per member account. Analyzing and committing at the management (payer) account level maximizes discount coverage and utilization because commitments are shared across all linked accounts.
Analyze across the organization
Aggregate usage at the payer account: Use consolidated billing so usage from all member accounts rolls up to the management account, and analyze pricing-model opportunities against that aggregate rather than account-by-account.
Use organization-wide recommendations: Review Savings Plans and Reserved Instance recommendations at the management account level in AWS Cost Explorer, which account for combined usage and surface higher-value, better-utilized commitments.
Commit and manage centrally
Purchase centrally where it maximizes coverage: Make Savings Plans / RI purchases at the management account so the discount benefit is shared across the organization and idle commitment in one account can be absorbed by another.
Monitor coverage and utilization: Track commitment coverage and utilization organization-wide, and adjust future commitments based on aggregate trends.
Balance with account autonomy: Where teams need their own commitments, combine central analysis with account-level purchases, keeping visibility at the payer account.
AWS Services to Consider
AWS Cost Explorer (Savings Plans & RI recommendations)
Generate commitment recommendations against aggregated organization-wide usage at the management account.
AWS Organizations consolidated billing
Rolls up member-account usage to the payer account so pricing-model analysis spans the whole organization.
Savings Plans & Reserved Instances
Shared across linked accounts when purchased at the management account, maximizing coverage and utilization.
