Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS) are generally known as which of the following?

IaaS, PaaS, and SaaS are indeed referred to as service models within cloud computing. These service models define the different levels of abstraction and services provided by cloud providers to customers.

Infrastructure-as-a-Service (IaaS) offers virtualized computing resources over the internet, allowing users to manage operating systems and applications while the provider takes care of the physical infrastructure. Platform-as-a-Service (PaaS) provides a platform allowing customers to develop, run, and manage applications without dealing with the complexities of building and maintaining the underlying infrastructure. Software-as-a-Service (SaaS) delivers software applications over the internet, eliminating the need for local installation and maintenance.

These models are foundational to understanding how cloud services function, as they illustrate the varying degrees of control, flexibility, and management that a user can expect from a cloud solution. Options referencing deployment models, frameworks, or architectures focus on different aspects of cloud computing and do not categorize IaaS, PaaS, and SaaS accurately in terms of their primary function and offering.
