Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

____ is the feature of cloud computing that allows the service to change in size or volume in order to meet a user‟s needs.

A	Scalability
B	Virtualization
C	Security
D	Cost-savings

Explanation:

Detailed explanation-1: -Cloud elasticity is a popular feature associated with scale-out solutions (horizontal scaling), and it allows for resources to be dynamically added or removed when needed.

Detailed explanation-2: -On-demand self-service: An end-user can unilaterally provision computing capabilities, such as server settings and network storage when needed, without any interaction from the provider’s IT administrator.

Detailed explanation-3: -Storing and processing big volumes of data requires scalability, fault tolerance and availability. Cloud computing delivers all these through hardware virtualization. Thus, big data and cloud computing are two compatible concepts as cloud enables big data to be available, scalable and fault tolerant.
