A non-profit must support seasonal events that cause short spikes in web traffic. Which cloud feature is most helpful?

Elasticity is the ability of a cloud system to automatically scale resources up or down to meet demand. For seasonal events with traffic spikes, elasticity ensures the application can handle the increased load without manual intervention and then scale back down to save costs when demand decreases. Disaster recovery focuses on business continuity after a major outage, not traffic spikes. Agility refers to the ability to rapidly develop, test, and deploy applications, which is a broader cloud benefit but not specific to handling traffic spikes. Geo-distribution involves deploying resources across multiple geographic regions for redundancy and lower latency, which is not the primary solution for fluctuating demand within a single region.
