Which NIST cloud service model does not require the customer organization to do any programming?

IaaS
PaaS
FaaS
SaaS

The correct answer is: SaaS

The choice of Software as a Service (SaaS) is correct because this cloud service model provides fully developed software applications that are managed and hosted by a third-party provider. With SaaS, customers access applications over the internet without the need for installation, maintenance, or programming. This model allows users to utilize software solutions immediately, which is especially beneficial for those who want to avoid the complexities of development and deployment. In contrast, Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) do require some level of programming or configuration by the customer. IaaS gives customers access to raw computing resources, such as virtual machines and storage, requiring them to manage and configure their own applications, operating systems, and programming. Similarly, PaaS provides a platform allowing developers to build, deploy, and manage applications, necessitating coding and program maintenance from the customer. Function as a Service (FaaS), while more specialized, also involves some programming for creating serverless functions and managing application logic. Overall, SaaS stands out as the model that eliminates the need for customer-side programming, making it more accessible for users seeking a turnkey software solution.
