CompTIA Cloud Essentials+ (CLO-002)Cloud ConceptsMedium
A global e-commerce company experiences predictable traffic spikes during holiday seasons and flash sales. They want to ensure their application can handle these increased loads without over-provisioning resources during off-peak times. Which characteristic of cloud computing specifically addresses this requirement by automatically adjusting resources?
- AHigh Availability
- BElasticity
- CResilience
- DScalability
Show answer & explanationAnswer & explanation
Correct answer: B. Elasticity
Elasticity refers to the ability of a system to automatically scale resources up or down in response to changing demand, which directly addresses the need for handling predictable traffic spikes without over-provisioning.
Why the other options are wrong
- A. High Availability ensures continuous operation despite failures, but doesn't specifically address automatic resource adjustment for demand.
- C. Resilience is the ability to recover from failures and maintain service, not about dynamic resource scaling for demand.
- D. Scalability is the ability to handle increased load by adding resources, but doesn't imply automatic adjustment.
Elasticity (Cloud)
The ability of a cloud computing system to automatically increase or decrease the amount of computing resources in real-time, based on the current workload or demand.
- Automatic scaling up and down.
- Optimizes cost by only paying for resources when needed.
- Ensures performance during peak and off-peak times.
Memory trick: Elasticity stretches and shrinks with the flow.
