High availability
B
Security
C
Reliability
D
Elasticity
Explanation:
Explanation
Elasticity is the correct answer because it refers to the ability of cloud resources to scale up or down automatically based on demand. This allows companies to:
- Handle peak usage without purchasing additional on-premises equipment
- Scale resources dynamically as application traffic increases or decreases
- Pay only for what they use rather than investing in infrastructure for maximum potential load
Why other options are incorrect:
- High availability: Focuses on ensuring applications remain accessible and operational, typically through redundancy and failover mechanisms.
- Security: Refers to protecting data, applications, and infrastructure from threats and unauthorized access.
- Reliability: Involves the ability of a system to recover from failures and continue functioning as expected.
Key AWS services that provide elasticity:
- Amazon EC2 Auto Scaling: Automatically adjusts the number of EC2 instances
- AWS Elastic Load Balancing: Distributes traffic across multiple targets
- Amazon S3: Automatically scales storage capacity
- AWS Lambda: Scales compute capacity automatically based on request volume
The company's specific need to handle peak usage without purchasing on-premises equipment directly aligns with the elasticity benefit of cloud computing.
