Microsoft Azure Fundamentals (AZ-900)Describe cloud conceptsEasy
A retail company experiences massive spikes in website traffic during holiday sales events, but very low traffic at other times. They want to ensure their website never goes down during peak times and avoid paying for idle resources during off-peak times. Which benefit of cloud computing is most relevant to their situation?
- AScalability & Elasticity
- BReduced CapEx
- CGlobal Reach
- DSecurity
Show answer & explanationAnswer & explanation
Correct answer: A. Scalability & Elasticity
The ability to handle massive traffic spikes (scalability) and automatically adjust resources to avoid paying for idle capacity (elasticity) directly addresses the retail company's problem of fluctuating demand and cost optimization. This ensures high availability during peaks and cost savings during troughs.
Why the other options are wrong
- B. Reduced CapEx is a general cloud benefit, but not the most direct solution for traffic spikes.
- C. Global Reach is for distributed users, not primarily for handling demand fluctuations.
- D. Security is a core concern but doesn't directly solve traffic spike or idle resource issues.
Scalability & Elasticity
Scalability is the ability to handle increased workload by adding resources. Elasticity is the ability to automatically and dynamically adjust resources to meet fluctuating demand, typically scaling down when demand decreases to save costs.
- Scalability ensures performance under high load.
- Elasticity optimizes cost by matching resources to current demand.
- Crucial for applications with unpredictable or seasonal traffic patterns.
- Contributes to high availability and cost-effectiveness.
