Difficulty: HardDefine the benefits of the AWS Cloud

A digital health startup is transitioning its core genomic sequencing pipelines to AWS. Previously, the company had to buy expensive high-performance computing (HPC) hardware upfront, which took months to write off as capital depreciation. On AWS, they pay only for the compute hours their pipelines consume, allowing them to fund ongoing development directly from their operational budget. However, their CFO notices that because AWS aggregates usage from hundreds of thousands of active customers, the pay-as-you-go pricing for these compute resources is significantly lower than what the startup could negotiate on their own. Which benefit of the AWS Cloud is primarily responsible for the lower per-unit resource cost observed by the CFO?

  1. Benefit from massive economies of scaleAnswer
  2. B
    Trade capital expense for variable expense
  3. C
    Stop guessing capacity
  4. D
    Stop spending money running and maintaining data centers

Answer

Benefit from massive economies of scale
The correct answer is the option stating 'Benefit from massive economies of scale'. By aggregating resource usage across hundreds of thousands of active customers, AWS can achieve higher economies of scale. This translates into lower pay-as-you-go prices for individual customers than they could achieve on their own.

Step-by-Step Solution

1
Analyze the scenario details to identify the primary financial benefit being queried.
The CFO is noticing a lower per-unit resource cost obtained through aggregated customer demand.
This isolates the question from the general pay-as-you-go benefits to the specific driver of reduced pricing.
2
Differentiate between the AWS Cloud benefits related to cost.
Trading capital expense for variable expense describes the shift from CapEx to OpEx. Benefiting from massive economies of scale describes the lower per-unit pricing achieved through aggregation.
Ensures the correct classification of AWS's pricing advantage vs. the customer's billing model.
3
Select the benefit that corresponds to aggregated usage reducing unit pricing.
The correct benefit is 'Benefit from massive economies of scale'.
AWS passes these savings onto customers in the form of lower prices.

Key Concept

AWS Cloud economies of scale drive lower pricing through customer aggregation.
