Microsoft Azure Fundamentals (AZ-900)Describe cloud conceptsMedium
A global e-commerce company experiences significant traffic spikes during major sales events. They need a cloud solution that can automatically and instantaneously provision and de-provision computing resources to handle these unpredictable demands, ensuring continuous performance without over-provisioning during off-peak times. Which cloud benefit does this scenario primarily highlight?
- AFault Tolerance
- BHigh Availability
- CDisaster Recovery
- DElasticity
Show answer & explanationAnswer & explanation
Correct answer: D. Elasticity
Elasticity refers to the ability of a cloud system to automatically and quickly scale computing resources up or down to meet changing demands. This is crucial for handling unpredictable traffic spikes efficiently and cost-effectively, as described in the scenario.
Why the other options are wrong
- A. Fault tolerance ensures an application continues operating despite failures, but doesn't specifically address automatic scaling for demand.
- B. High availability ensures continuous uptime, but elasticity specifically addresses the automatic scaling aspect for fluctuating workloads.
- C. Disaster recovery focuses on restoring operations after a major incident, not dynamic scaling for traffic.
Elasticity (Cloud)
The ability of a cloud system to automatically and dynamically adjust the provisioned computing capacity to match the current workload demand, scaling up or down as needed.
- Automatic scaling of resources
- Responds to real-time demand
- Optimizes cost and performance
Memory trick: Elasticity stretches like a rubber band for your cloud.
