ChroniclePage, a digital publishing platform, is migrating its legacy content delivery system to AWS. The platform experiences high traffic volatility, with traffic peaking during major breaking news events and dropping significantly during late-night hours. The CFO wants to understand the economic advantages of this migration. Which two of the following describe the primary cloud economics benefits that ChroniclePage will realize after migrating to AWS?

  1. Shifting from upfront capital expenditures (CapEx) for physical hardware to a variable operating expenditure (OpEx) model.Answer
  2. Leveraging elasticity to dynamically align resource supply with fluctuating traffic, reducing the cost of idle capacity.Answer
  3. C
    Eliminating operating expenditures (OpEx) entirely by utilizing AWS upfront reservation plans to secure permanent hardware ownership.
  4. D
    Improving predictability by continuously over-provisioning compute resources to match historical peak load, eliminating the need to scale.
  5. E
    Rehosting the applications to automatically redesign the system architecture into loose, serverless components without additional cost.

Answer

The correct benefits are shifting from upfront capital expenditures (CapEx) for physical hardware to a variable operating expenditure (OpEx) model, and leveraging elasticity to dynamically align resource supply with fluctuating traffic.
The correct options describe shifting from upfront capital expenditures (CapEx) for physical hardware to a variable operating expenditure (OpEx) model, and leveraging elasticity to dynamically align resource supply with fluctuating traffic. By migrating to AWS, ChroniclePage avoids high initial hardware costs (CapEx) and instead pays variable operational fees (OpEx). Using elasticity, the platform dynamically scales down during low-traffic periods, preventing financial waste from idle capacity.

Step-by-Step Solution

1
Analyze ChroniclePage's business scenario and workload characteristics.
The workload has high traffic volatility with sharp peaks (breaking news) and valleys (late-night hours).
Understanding the traffic pattern helps identify how cloud elasticity impacts resource consumption and costs.
2
Evaluate the financial impact of shifting from on-premises data centers to AWS.
On-premises requires capital expenses (CapEx) for hardware, whereas AWS uses a pay-as-you-go operating expenditure (OpEx) model.
Shifting from CapEx to OpEx allows the company to avoid heavy upfront investments and instead pay variable operational costs.
3
Assess how elasticity addresses the cost of volatile workloads.
Elasticity allows the infrastructure to scale up or down automatically, matching resources to actual demand and eliminating the cost of idle servers.
Elasticity directly reduces waste, optimizing the Total Cost of Ownership (TCO) compared to static over-provisioning.
