The concept that most IT requirements can be deployed as a cloud service model.

• A. Cloud computing
• B. Anything as a Service (XaaS)
• C. Software as a Service (SaaS)
• D. Platform as a Service (PaaS)

Answer: (B)

Delivering IT capabilities as on-demand services over the cloud. This idea is captured by Anything as a Service (XaaS), the umbrella term for providing nearly any IT function as a service—from software and platforms to infrastructure and more. XaaS encompasses SaaS, PaaS, IaaS, and other service models, reflecting the flexibility to deploy a wide range of requirements as cloud-based services with on-demand provisioning and pay-as-you-go pricing. While SaaS and PaaS are specific examples under this umbrella, and cloud computing is the broader paradigm, XaaS best fits the notion that most IT needs can be delivered as a cloud service.
