Difficulty: EasyUnderstand concepts of cloud economics

A news publishing website experiences unpredictable spikes in website traffic when major stories break, but has very low traffic during normal hours. By hosting their application on AWS, the publisher can dynamically provision compute resources to handle traffic surges and automatically terminate those resources when traffic subsides. Which concept of cloud economics does this scenario directly illustrate?

  1. A
    The shift from operating expenses (OpEx) to capital expenses (CapEx)
  2. B
    The provisioning of resources to meet maximum peak load scalability
  3. The cost benefits of elasticityAnswer
  4. D
    The implementation of a monolithic infrastructure design

Answer

The cost benefits of elasticity
The correct answer is correct because elasticity allows an organization to dynamically adjust resource capacity to match shifting demand. This ensures that they only pay for what they use, minimizing costs during periods of low traffic while maintaining performance during surges.

Step-by-Step Solution

1
Analyze the organization's resource utilization pattern in the scenario.
The news publisher experiences fluctuating, unpredictable website traffic with high peaks and low valleys.
Understanding the demand pattern helps determine which cloud economic principle applies to resource management.
2
Identify the AWS mechanism that allows resources to dynamically scale up and down to match this demand.
Elasticity allows resources to be added when demand increases and removed when demand decreases, ensuring costs scale directly with usage.
This mechanism aligns resource provisioning with consumption, which minimizes waste and optimizes costs.
