Cloud computing is best described as which of the following?

A.
Distributed load balanced servers

B.
Delivering software as a service

C.
Large scale distributed computing

D.
Distributed virtualized servers

Explanation:
The main focus of cloud computing is about delivering software as a service or operating systems as a service. They may or may not be on distributed computing systems. Answer option C is incorrect. Large scale distributed computing is called grid computing. Answer option A is incorrect. Load balancing is what edge computing is about. It may be that cloud computing also accomplishes load balancing, but that is not the primary purpose.

Answer option D is incorrect. Cloud computing may be accomplished via virtualization. but it need not be. Virtualized computing is about the way the systemis hosted, not necessarily theservers distribution (as with cloud and grid computing).
