App1 has low usage during the first three weeks of each month and very high usage during the last week. Which benefit of Azure Cloud Services helps manage costs for this usage pattern?

Elasticity is the ability of a cloud system to automatically scale resources up or down based on demand. For App1, this means Azure can provision fewer resources during low-usage periods and automatically add more during the high-usage last week, optimizing costs by paying only for what is needed. High availability ensures the application remains accessible during outages, but doesn't directly address cost management for fluctuating demand. High latency refers to delays in data transmission and is generally undesirable, not a benefit. Load balancing distributes incoming traffic across multiple resources to ensure optimal performance and reliability, but it doesn't inherently scale resources up or down based on usage patterns to manage costs.
