Which term describes dynamically adjusting cloud resources to meet real-time demand?

Elasticity is the correct term because it refers to the ability of a cloud system to automatically scale resources up or down based on demand. This dynamic adjustment ensures optimal performance and cost efficiency. Agility describes the ability to respond quickly to change, but doesn't specifically refer to resource scaling. High availability ensures that a service remains operational even if some components fail, focusing on uptime rather than dynamic resource adjustment. Redundancy involves duplicating components to prevent single points of failure, which contributes to high availability but isn't the primary term for dynamic scaling.
