In the context of cloud computing, what term describes the ability to automatically adjust resources to meet changing demands?

1. Auto-scaling

2. Elasticity

3. Resource allocation

4. High availability

The correct answer is: Auto-scaling

The term that best describes the ability to automatically adjust resources to meet changing demands in cloud computing is "Elasticity." This concept refers to the cloud's capability to dynamically scale resources up or down based on current needs, allowing for efficient use of resources and cost management. Elasticity is a fundamental characteristic of cloud environments, enabling users to handle fluctuating workloads seamlessly. When demand increases, elastic systems can provision additional resources automatically without manual intervention. Conversely, when demand decreases, those resources can be reduced, ensuring that costs are effectively managed and not wasted on unused capacity. While auto-scaling is a related feature that facilitates this process by automatically adjusting resources, elasticity encompasses the broader concept of dynamic resource management necessary to respond to variable demands. Thus, while auto-scaling is important, it is a component of the overarching principle of elasticity in cloud computing.
