Bernard is considering using a new cloud service where the vendor offers a managed environment for the execution of customer-supplied code. What term best describes this service?
Correct Answer: B
This environment, where customers supply code and vendors supply managed infrastructure, is known as platform as a service (PaaS) computing. In infrastructure as a service (IaaS) computing, the vendor offers access to the basic building blocks of a computing infrastructure, such as servers, storage, and networking and the customer assembles those building blocks to create their own solutions. In the software as a service (SaaS) model, the vendor provides a fully functional application to the customer. Anything as a service (XaaS) is a term describing the fact that virtually any computing service may be delivered in a cloud model and it is not a good description of this specific scenario.
