A company would like to maximize their potential volume and Reserved Instance discounts across multiple accounts and also apply service control policies on member accounts. Which service or tool can they use to gain these benefits?

AWS Organizations enables you to create groups of AWS accounts and then centrally manage policies across those accounts. AWS Organizations provides consolidated billing in both feature sets, which allows you set up a single payment method in the organization’s master account and still receive an invoice for individual activity in each member account. Volume pricing discounts can be applied to resources.
