Question

Which of the following is a cloud computing feature that allows consumers to control the volume and type of computing resources used?

1) Virtualization
2) Scalability
3) Elasticity
4) Resource pooling

Answer 1

Elasticity is the cloud computing feature that allows consumers to actively manage and automatically adjust the volume and type of computing resources utilized in real time.

Step-by-step explanation:

The cloud computing feature that allows consumers to control the volume and type of computing resources used is known as elasticity. This is distinct from scalability, which refers to the potential to increase or decrease systems, but doesn't necessarily refer to the active management of that scale.

Elasticity allows for the automatic scaling of resources to meet demand, effectively letting users pay only for what they use and scale their resources up or down as needed in real time.

Virtualization is the creation of a virtual version of something, such as hardware, but is not specifically about scaling. Resource pooling refers to the cloud provider's ability to serve multiple consumers with provisioned resources, which are dynamically assigned according to consumer demand, but it doesn't cover consumer control over the resources in terms of volume and type.
