Question
A company needs to deploy its own code directly in the cloud without provisioning additional infrastructure. Which of the following is the best cloud service model for the company to use?
- A. PaaS Correct
- B. SaaS
- C. IaaS
- D. XaaS
Explanation
Platform as a service lets a company deploy its own code onto a managed runtime while the provider handles servers, operating systems and scaling, so no infrastructure has to be provisioned. IaaS requires the customer to provision and manage virtual machines and networks. SaaS delivers a finished application rather than running the customer's code, and XaaS is a general umbrella term.
