Answer: Elasticity

## 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.
