Which of the following is NOT one of the five essential characteristics of cloud computing described by the National Institute of Standards and Technology?
- A.On-demand self-service
- B.Resource pooling
- C.Rapid elasticity
- D.Permanent offline operation
Correct answer
Explanation
The correct answer is D, permanent offline operation. The cloud is reached over a network, so working permanently offline is the opposite of what the model offers; the dependence on connectivity is in fact listed among the limitations of cloud computing. Options A, B and C are wrong as answers because all three are genuine characteristics. On-demand self-service means a user can take storage or a server without talking to anyone. Resource pooling means the provider serves many customers from the same physical machines. Rapid elasticity means capacity can grow or shrink within minutes as demand changes. The two remaining characteristics are broad network access, that is availability across devices and networks, and measured service, where usage is metered and billed. This set of five is a favourite of banking papers.
