Zorluk: OrtaUnderstand concepts of cloud economics

A digital publishing platform experiences highly variable web traffic, with sudden surges during breaking news events and minimal activity overnight. The platform owners want to migrate to AWS to avoid purchasing and maintaining physical servers sized for their peak traffic. Which of the following cloud economics concepts best explains how this migration helps the company optimize its infrastructure costs?

  1. A
    Trading variable operating expenses for upfront capital expenses, which enables the company to own its cloud infrastructure over time.
  2. B
    Relying on scalability to dynamically allocate and deallocate resources in real time to match the hourly changes in user traffic.
  3. Trading capital expenses for variable operating expenses, which allows the company to pay only for the compute resources it consumes.Cevap
  4. D
    Utilizing Spot Instances to guarantee constant, uninterrupted capacity for the primary relational database during breaking news events.

Cevap

Trading capital expenses for variable operating expenses, which allows the company to pay only for the compute resources it consumes.
The correct option describes the core cloud economics benefit of trading capital expenses (upfront hardware purchases) for variable operating expenses (paying only for resources used). This allows the platform to scale down during low-activity periods and avoid paying for idle capacity.

Adım Adım Çözüm

1
Analyze the company's requirement to avoid upfront physical hardware costs for peak traffic.
Identify that purchasing hardware for peak capacity represents a Capital Expense (CapEx) where hardware is underutilized during low-traffic periods.
Understanding the baseline operational challenges of on-premises infrastructure is key to identifying the correct cloud economic benefit.
2
Evaluate the financial transition model when migrating to AWS.
AWS enables an Operating Expense (OpEx) model where costs are variable and scale directly with consumption.
Trading capital expenses for variable expenses is a core pillar of AWS cloud economics.
