Difficulty: MediumDefine the benefits of the AWS Cloud

A startup in the digital health sector is launching a telemedicine platform. The company's leadership wants to avoid purchasing expensive physical servers and storage arrays upfront. Additionally, they are uncertain about the daily patient volume, making it difficult to predict the exact resource requirements needed to prevent application downtime. Which of the following AWS Cloud benefits directly address these business requirements? (Select TWO.)

  1. Trade fixed expense for variable expenseAnswer
  2. Stop guessing capacityAnswer
  3. C
    Prioritize capital expense (CapEx) over operating expense (OpEx) for long-term predictability
  4. D
    Scale resources manually to ensure fixed capacity levels
  5. E
    Deploy tightly coupled architectures to minimize network latency

Answer

Trading fixed expense for variable expense and stopping guessing capacity are the correct answers.
Trading fixed expense for variable expense allows the startup to avoid high upfront infrastructure costs by paying only for consumed resources. Stopping guessing capacity ensures that the application automatically scales to handle traffic spikes, preventing downtime without over-provisioning resources.

Step-by-Step Solution

1
Analyze the scenario requirements.
The startup needs to avoid high upfront server/storage costs and manage unpredictable resource demand to prevent downtime.
This helps map the business challenges to the official AWS Cloud benefits.
2
Evaluate the first requirement: avoiding upfront costs.
Trading fixed expense for variable expense allows the company to pay as they go instead of investing heavily in upfront hardware.
This directly aligns with the economic benefit of cloud computing over on-premises data centers.
3
Evaluate the second requirement: handling uncertain daily patient volume.
Stopping guessing capacity allows the system to scale resources automatically up or down based on actual usage.
This prevents application downtime from under-provisioning and saves cost from over-provisioning.
