Difficulty: MediumUnderstand concepts of cloud economics

A digital food delivery startup, QuickBite, experiences predictable surges in traffic daily during lunch and dinner hours, while traffic during the night is negligible. The company is migrating its ordering system to AWS. Which of the following describes the most significant economic advantage of this migration regarding cost optimization?

  1. A
    The opportunity to transition from variable operating expenses to predictable upfront capital expenses for their compute infrastructure.
  2. B
    The ability to scale up the capacity of their database servers to handle lifetime customer growth over a long-term horizon.
  3. The ability to dynamically provision and terminate resources to align with fluctuating daily demand, minimizing cost during low-traffic periods.Answer
  4. D
    The requirement to purchase Spot Instances for all core transaction processing services to guarantee uninterrupted availability at the lowest cost.

Answer

The ability to dynamically provision and terminate resources to align with fluctuating daily demand, minimizing cost during low-traffic periods.
The correct option is correct because the food delivery startup has variable daily workloads. By using cloud elasticity, they can dynamically provision resources during high-traffic lunch and dinner times and terminate them during low-traffic hours, minimizing operational costs.

Step-by-Step Solution

1
Identify the workload characteristics of the startup.
The workload has high peaks during meal hours and extremely low demand overnight.
Understanding the traffic pattern helps determine the appropriate resource management strategy.
2
Evaluate how AWS pricing models and features address this workload pattern.
Elasticity allows the startup to scale resources up and down to match demand, using pay-as-you-go pricing.
Dynamic scaling ensures that the company does not pay for idle capacity during low-traffic periods.
3
Compare options to find the one representing this economic advantage.
Aligning resource provisioning dynamically with daily demand optimizes costs.
This directly matches the cloud economics principle of elasticity and variable cost optimization.
