A small company is considering moving many of its data center functions to the cloud. What are three advantages of this plan? (Choose three.) The company only needs to pay for the amount of processing and storage capacity that it uses. Cloud services are billed at a fixed fee no matter how much processing and storage are used by the company. Cloud services enable the company to own and administer its own servers and storage devices. The company can increase processing and storage capacity as needed and then decrease capacity when it is no longer needed.
