Microsoft 365 FundamentalsDescribe cloud conceptsHard
A global e-commerce company experiences predictable, significant spikes in website traffic during major shopping holidays. They need a cloud solution that can automatically adjust computing resources to handle these sudden increases in demand and then scale back down when the peak passes, without manual intervention. Which cloud benefit does this scenario primarily describe?
- AScalability
- BElasticity
- CHigh Availability
- DFault Tolerance
Show answer & explanationAnswer & explanation
Correct answer: B. Elasticity
Elasticity refers to the ability of a cloud system to automatically and dynamically adjust resources to meet fluctuating demand without human intervention, scaling both up and down as needed. This is distinct from scalability, which implies the ability to handle increased load but not necessarily the automatic, dynamic adjustment both up and down.
Why the other options are wrong
- A. Scalability is the ability to handle increased load, but doesn't necessarily imply automatic, dynamic scaling both up and down.
- C. High availability ensures continuous operation, not automatic resource adjustment based on demand.
- D. Fault tolerance ensures continued operation despite component failures, which is different from adjusting resources for demand.
Elasticity (Cloud)
The ability of a cloud system to automatically and dynamically expand or shrink its computing resources in response to changes in workload demand, without human intervention.
- Automatic scaling up and down.
- Responds to real-time demand fluctuations.
- Optimizes cost by only using resources when needed.
