Difficulty: MediumUnderstand concepts of cloud economics

A logistics company, ShipRapid, plans to migrate its package tracking and routing platform to the AWS Cloud. Currently, the company pays upfront for physical servers and data center infrastructure on a five-year refresh cycle, even though resource utilization fluctuates daily and spikes heavily during the holiday season. Which TWO of the following benefits of AWS cloud economics directly address this company's challenges? (Select TWO.)

  1. Shifting from upfront capital expenses (CapEx) to variable operating expenses (OpEx), paying only for computing resources when they are activeAnswer
  2. Leveraging cloud elasticity to dynamically scale resources up and down to match demand, minimizing cost during low-use periodsAnswer
  3. C
    Converting variable operating expenses (OpEx) into fixed capital expenses (CapEx) to guarantee long-term infrastructure budget predictability
  4. D
    Relying on vertical scalability to permanently size the servers to handle maximum holiday peak capacity
  5. E
    Deploying all persistent database workloads on On-Demand Instances to completely avoid upfront commitment plans

Answer

The benefits that align with AWS cloud economics are shifting from upfront capital expenses to variable operating expenses, and leveraging cloud elasticity to dynamically scale resources to match demand.
AWS cloud economics helps businesses transition from a capital expense (CapEx) model, where they pay for physical infrastructure upfront, to a variable operational expense (OpEx) model, where they pay only for what they consume. In addition, elasticity allows resources to scale dynamically in response to real-time demand fluctuations, reducing costs associated with idle, over-provisioned infrastructure during off-peak times.

Step-by-Step Solution

1
Analyze the company's current on-premises pain points regarding hardware refresh cycles and seasonal/daily demand fluctuations.
Identify that upfront 5-year purchasing represents high Capital Expenses (CapEx), and provisioning for holiday spikes leads to wasted costs due to low daily utilization.
Understanding the baseline financial and operational challenges is necessary to determine which cloud economics concepts apply.
2
Evaluate the financial benefit of transitioning physical server costs to AWS.
Determine that moving to a consumption-based model shifts CapEx to variable Operating Expenses (OpEx), directly addressing the 5-year upfront cycle cost.
This shows how AWS pricing models resolve the budget rigidity of on-premises hosting.
3
Evaluate the operational benefit of scaling resources dynamically to match varying load.
Determine that elasticity allows the package tracking system to scale down during low-traffic periods, avoiding costs for idle resources while scaling up for peak holiday seasons.
This links the technical capability of elasticity to the economic benefit of cost optimization.
