AWS Certified Cloud Practitioner (CLF-C02)Cloud ConceptsMedium
A video streaming service experiences unpredictable spikes in demand during major live events. They need a solution that can automatically adjust computing capacity to match demand without manual intervention, ensuring a smooth user experience while optimizing costs. Which AWS cloud benefit primarily addresses this requirement?
- ASecurity
- BHigh Availability
- CElasticity
- DAgility
Show answer & explanationAnswer & explanation
Correct answer: C. Elasticity
Elasticity is the ability to automatically scale computing resources up or down to match demand. This directly addresses the need for automatic adjustment during unpredictable spikes, ensuring performance and cost optimization.
Why the other options are wrong
- A. Security focuses on protecting data and systems, not dynamic capacity adjustment.
- B. High Availability ensures systems remain operational, but doesn't specifically address automatic scaling with demand fluctuations.
- D. Agility refers to the speed of development and deployment, not dynamic resource scaling.
Elasticity
The ability to automatically and rapidly provision and de-provision computing resources to match fluctuating demand, reducing over-provisioning and under-provisioning.
- Key for workloads with variable demand.
- Achieved through services like Auto Scaling.
- Optimizes cost by paying only for what's used.
Memory trick: Elastic cloud: stretches with demand.
