Which cloud service model provides ready-to-use applications such as email and office apps?

• A. Software as a Service (SaaS)
• B. Infrastructure as a Service (IaaS)
• C. Platform as a Service (PaaS)
• D. Network as a Service (NaaS)

Answer: (A)

SaaS provides software that you can use right away over the internet. The provider hosts and maintains the applications, handling updates, security, and scalability, so you don’t install or manage the software or the underlying infrastructure. This makes it ideal for ready-to-use tools like email and office apps, where the goal is immediate access and minimal setup. In contrast, IaaS focuses on renting virtualized hardware and storage, offering the building blocks to run your own systems. PaaS gives a platform to develop, deploy, and manage your own applications, handling runtime and middleware but not delivering finished software to end users. NaaS centers on providing network services rather than software applications.
