Which AWS value proposition describes the ability to scale infrastructure up or down based on demand?

Resource elasticity is the ability to acquire and release computing resources dynamically, scaling up or down to meet changing demand. This means you only pay for the resources you use, optimizing costs and performance. Speed of innovation refers to the ability to quickly develop and deploy new applications and features, but doesn't directly describe scaling. Decoupled architecture involves separating components of an application so they can operate independently, improving resilience and scalability, but isn't the direct term for scaling infrastructure. Global deployment refers to the ability to deploy applications across multiple AWS regions worldwide, which is a different benefit.
