Zorluk: ZorUnderstand concepts of cloud economics

A smart grid utility operator runs complex grid-reliability simulations once a week. This process requires a large amount of compute capacity for a 6-hour window, but the infrastructure remains completely idle for the rest of the week. Currently, the company maintains an on-premises data center sized to handle this peak load, incurring high upfront costs, virtualization licensing, power, and cooling fees. Which of the following best describes the primary economic driver and financial shift of migrating this simulation workload to AWS?

  1. Transitioning from capital expenses (CapEx) to operating expenses (OpEx), allowing the company to leverage AWS elasticity and pay only for compute resources during the active simulation window.Cevap
  2. B
    Eliminating all operating expenses (OpEx) by converting ongoing maintenance and utility fees into upfront capital expenses (CapEx) using AWS enterprise agreements.
  3. C
    Improving resource scalability by pre-provisioning a static fleet of EC2 instances sized for peak performance, ensuring that maximum compute power is permanently online.
  4. D
    Minimizing the total cost of ownership by deploying the simulations on On-Demand instances while purchasing a 3-year Spot Instance commitment to cover the idle periods.

Cevap

Transitioning from capital expenses (CapEx) to operating expenses (OpEx), allowing the company to leverage AWS elasticity and pay only for compute resources during the active simulation window.
Transitioning from capital expenses (CapEx) to operating expenses (OpEx) is a core benefit of AWS. By leveraging AWS elasticity, the utility only incurs costs when the simulations run, eliminating the overhead of idle infrastructure.

Adım Adım Çözüm

1
Analyze the workload's resource usage pattern.
The workload requires high compute capacity for 6 hours once a week, remaining idle for the other 162 hours of the week.
Identifying the pattern helps determine the appropriate cloud architecture and pricing model.
2
Evaluate the financial shift of cloud migration.
Moving away from owning and maintaining physical data centers shifts expenses from Capital Expenses (CapEx) to Operating Expenses (OpEx).
This is a fundamental concept of cloud economics where fixed upfront costs are replaced by variable expenses.
3
Apply the principle of cloud elasticity to the workload.
By scaling down resources to zero during the idle hours, the company only pays for the active 6 hours of simulation runtime.
Elasticity ensures cost optimization by aligning resource provisioning directly with real-time demand.
