Zorluk: OrtaUnderstand concepts of cloud economics

SmartHaven, an IoT smart home provider, is planning to migrate its device telemetry ingestion platform from an on-premises data center to AWS. The platform experiences massive traffic spikes every evening when users return home, but remains mostly idle during the night. Which of the following describe the economic advantages of migrating this workload to AWS? (Select TWO.)

  1. Replacing upfront capital expenses (CapEx) with variable operating expenses (OpEx)Cevap
  2. Leveraging elasticity to dynamically scale resources to match the evening demand peaks, reducing costs during idle hoursCevap
  3. C
    Converting variable operating expenses (OpEx) into fixed capital expenses (CapEx) to make monthly costs fully predictable
  4. D
    Ensuring scalability by continuously running resources at peak capacity to handle long-term organic user growth
  5. E
    Reducing core database costs by running stateful, time-critical evening writes exclusively on Spot Instances

Cevap

The correct options are: replacing upfront capital expenses (CapEx) with variable operating expenses (OpEx); and leveraging elasticity to dynamically scale resources to match the evening demand peaks, reducing costs during idle hours.
The correct options are the ones stating that the company can replace upfront capital expenses (CapEx) with variable operating expenses (OpEx), and leverage elasticity to dynamically scale resources to match the evening demand peaks. The shift to OpEx allows the company to avoid heavy initial infrastructure investments, while elasticity ensures they do not pay for idle servers during the low-traffic night hours.

Adım Adım Çözüm

1
Analyze the financial transition in cloud migration.
Identify that cloud migration shifts financial models from purchasing hardware upfront (capital expenses) to a pay-as-you-go consumption model (operating expenses).
This determines the validity of CapEx and OpEx cost descriptions.
2
Evaluate how the workload's seasonal/daily demand pattern affects resource utilization.
The evening peak and nightly idle pattern means capacity requirements are variable. Leveraging elasticity allows the company to run resources only when needed, avoiding paying for idle capacity.
This validates the role of elasticity in reducing waste and cost.
3
Assess the incorrect options for architectural and billing mismatches.
Reject options that describe shifting to CapEx, running at peak capacity continuously (which eliminates the benefit of elasticity), or misapplying Spot Instances to critical, stateful databases.
This eliminates distractors based on common cloud economics misconceptions.
