Microsoft Azure Fundamentals (AZ-900)Describe cloud conceptsHard
A technology startup is developing a new online gaming platform that is expected to experience massive and unpredictable spikes in user traffic, especially during new game releases or seasonal events. They need a cloud solution that can automatically and instantaneously adjust its computing resources up or down to match these fluctuations without manual intervention, while optimizing costs. Which cloud capability is central to meeting this specific requirement?
- AFault Tolerance
- BGeographic Distribution
- CHigh Availability
- DElasticity
Show answer & explanationAnswer & explanation
Correct answer: D. Elasticity
Elasticity is the specific cloud capability that enables systems to automatically and instantaneously scale computing resources up or down to match unpredictable demand, which is crucial for handling massive traffic spikes efficiently and cost-effectively.
Why the other options are wrong
- A. Fault tolerance focuses on resilience against component failures to prevent downtime, not dynamic resource adjustment.
- B. Geographic distribution places resources in different regions for latency and disaster recovery, not for automatic workload-based scaling.
- C. High availability ensures uptime but doesn't specifically address automatic, dynamic scaling for unpredictable load changes.
Elasticity (Cloud Computing)
The ability of a cloud system to automatically and dynamically expand or shrink computing resources to match varying workloads in real time, often without manual intervention.
- Automatic scaling (up/down, out/in)
- Responds to unpredictable demand
- Optimizes costs by only using needed resources
Memory trick: Elasticity is the cloud's 'rubber band' for dynamic loads.
