Which term describes the ability to dynamically add resources in the cloud?

1. Burting

2. Pooling

3. Elasticity

4. Orchestration

The correct answer is: Elasticity

The term that describes the ability to dynamically add resources in the cloud is known as elasticity. Elasticity refers to the capability of a cloud environment to automatically scale resources up or down based on demand. This is a fundamental characteristic of cloud computing, allowing organizations to efficiently manage their computing resources to meet varying workload requirements without over-provisioning or under-utilizing the infrastructure. For instance, during peak usage times, a cloud service can automatically provision additional resources to handle the increased load, ensuring optimal performance. Conversely, when demand decreases, these resources can be scaled back down, allowing organizations to save on costs. This dynamic nature enables businesses to be more agile and responsive to changing needs. The other terms mentioned have different meanings in the context of cloud computing. Bursting typically refers to a scenario where an application runs in a private cloud but can use public cloud resources for overflow during high demand. Pooling is related to resource management where multiple users share a pool of resources, but it does not specifically address the dynamic scaling aspect. Orchestration involves the automation of managing, coordinating, and arranging different services and resources in the cloud, but it does not specifically denote the scaling abilities that elasticity captures.
