AWS defines elasticity in computing resources as dynamic resource allocation. This concept refers to the ability to automatically adjust the amount of computational resources, such as CPU, memory, and storage, based on the current demand. For instance, during peak traffic periods, AWS can provision additional resources to handle the increased load, and when the demand decreases, it can automatically scale down those resources. This ensures that users only pay for what they use and enhances both cost efficiency and performance.

The principle of elasticity is a core feature of cloud computing, allowing organizations to seamlessly adapt to changing workloads without the need for manual intervention or overprovisioning. This capability reflects how cloud services can promote agility and innovation by facilitating rapid scaling based on user needs.
