A. B. C. D.B.
The end user has purchased a SaaS solution.
SaaS stands for "Software as a Service." It refers to a cloud computing model in which a third-party provider hosts applications and makes them available to customers over the internet. In this model, users do not have to install or maintain any software themselves, and instead can access the application through a web browser or other client software.
In the case of a web-based calendar application, the user has signed up to use an application that is hosted by a third-party provider and accessed through the internet. This fits the SaaS model perfectly.
DaaS, or "Desktop as a Service," is a similar cloud computing model in which a third-party provider hosts virtual desktops and makes them available to users over the internet. This model is more focused on providing access to desktop environments rather than specific applications like a web-based calendar.
PaaS, or "Platform as a Service," is a cloud computing model in which a third-party provider hosts a platform for developing, testing, and deploying software applications. This model is more focused on providing developers with tools and infrastructure to build and deploy their own applications.
IaaS, or "Infrastructure as a Service," is a cloud computing model in which a third-party provider hosts and manages computing infrastructure such as servers, storage, and networking. This model is more focused on providing raw computing resources that customers can use to build their own applications and services.
So, in summary, the end user has purchased a SaaS solution to use a web-based calendar application.
