Question

Difficulty: MediumConsolidated Billing and AWS Organizations

A smart-home IoT provider manages separate AWS accounts for its device telemetry backend, customer database, and mobile application services. The finance department wants to consolidate billing for these accounts under a single AWS organization to optimize costs. Which of the following is a direct benefit of utilizing consolidated billing in AWS Organizations for this scenario?

  1. The combined usage across all member accounts is aggregated to qualify for volume pricing discounts on services such as Amazon S3.Answer
  2. B
    The management account can use Service Control Policies (SCPs) to establish and enforce maximum monthly spending limits in USD for each member account.
  3. C
    The credentials of the management account's root user are automatically distributed to member accounts to simplify resource administration.
  4. D
    Consolidating accounts shifts the overall AWS infrastructure spending from an operating expense (OpEx) model to a capital expense (CapEx) model.

Answer

The combined usage across all member accounts is aggregated to qualify for volume pricing discounts on services such as Amazon S3.
The correct answer is correct because AWS Organizations aggregates the usage from all member accounts in the organization, enabling the combined entity to qualify for volume tier discounts (such as S3 storage tier pricing or volume data transfer discounts) faster than individual standalone accounts.

Step-by-Step Solution

1
Analyze the requirements of the smart-home IoT provider's finance department to optimize costs across multiple accounts.
Identify that cost consolidation and pricing optimization are the primary goals.
This establishes that the solution must focus on consolidated billing capabilities.
2
Evaluate how AWS Organizations consolidated billing features apply to multi-account setups.
Note that AWS treats all member accounts in an organization as a single account for the purpose of calculating volume discounts.
This explains the mechanism of cost saving through volume tier aggregation.
