CompTIA Cloud Essentials+ (CLO-002)Business Principles of Cloud EnvironmentsMedium
A small e-commerce business is experiencing unpredictable spikes in customer traffic during seasonal sales and marketing campaigns. Their on-premises infrastructure frequently struggles to handle these peak loads, leading to slow response times and lost sales. Which cloud characteristic would primarily address this challenge?
- ABroad network access
- BResource pooling
- CRapid elasticity
- DMeasured service
Show answer & explanationAnswer & explanation
Correct answer: C. Rapid elasticity
Rapid elasticity is the ability of cloud resources to be quickly and automatically scaled up or down to meet fluctuating demand. This characteristic directly addresses the business's challenge of unpredictable traffic spikes, ensuring that resources are available when needed and scaled back during low periods to optimize costs.
Why the other options are wrong
- A. Broad network access refers to accessibility over standard network mechanisms, not dynamic scaling.
- B. Resource pooling refers to providers pooling resources to serve multiple consumers, not the ability to scale for a single consumer's fluctuating demand.
- D. Measured service refers to pay-per-use billing, not the core capability of dynamic resource allocation.
Rapid Elasticity
One of the essential characteristics of cloud computing, allowing resources to be provisioned and released rapidly and elastically, scaling outward and inward quickly to meet demand without human intervention.
- Automatic scaling of resources
- Handles fluctuating demand
- Prevents over-provisioning and under-provisioning
- Key for cost optimization and performance
