AWS Certified Cloud Practitioner (CLF-C02)Cloud ConceptsMedium
A global media company is designing a new video streaming platform on AWS. They need to ensure that the platform can automatically adjust its capacity to handle sudden, massive spikes in viewer traffic during live events, returning to normal capacity afterward to minimize costs. Which benefit of cloud computing does this scenario primarily describe?
- AHigh Availability
- BPay-as-you-go pricing
- CGlobal Reach
- DElasticity
Show answer & explanationAnswer & explanation
Correct answer: D. Elasticity
Elasticity is the ability of a system to automatically scale up or down its resources based on demand. This allows the media company to handle sudden traffic spikes without over-provisioning, and then scale back down to save costs.
Why the other options are wrong
- A. High Availability focuses on ensuring continuous uptime, often through redundancy, not dynamic scaling based on fluctuating demand.
- B. Pay-as-you-go pricing is a billing model, not a capability to automatically adjust capacity.
- C. Global Reach refers to deploying applications in multiple geographic regions, not dynamic capacity adjustment.
Elasticity
The ability of a system to automatically scale computing resources up or down to match demand, providing the right amount of resources at the right time.
- Automatic scaling.
- Responds to demand fluctuations.
- Optimizes cost and performance.
Memory trick: Elasticity stretches and shrinks with demand, like a rubber band.
