Which AWS tool or feature will share volume pricing discounts and Savings Plans among accounts?

Explanations:

AWS Budgets is a tool used to monitor costs and usage, allowing users to set custom cost and usage budgets. It does not facilitate sharing volume pricing discounts or Savings Plans among accounts.

Consolidated billing allows multiple AWS accounts to combine their usage, which enables sharing of volume pricing discounts and Savings Plans. This leads to reduced overall costs for the organization.

AWS credits are promotional credits provided by AWS that can be used to offset costs, but they do not inherently share volume pricing discounts or Savings Plans across accounts.

Cost allocation tags are used to track AWS costs by tagging resources, but they do not provide a mechanism for sharing volume pricing discounts or Savings Plans between accounts.
