What are the three basic service models of cloud computing?

The three basic service models of cloud computing are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). This framework is fundamental to understanding how cloud services are structured and delivered.

IaaS provides virtualized computing resources over the internet, allowing users to rent infrastructure such as servers, storage, and networking. This model gives users high flexibility and control, making it ideal for organizations that need to deploy complex applications or manage data without investing in physical hardware.

PaaS offers a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the underlying infrastructure. It includes tools and services to streamline processes in application development, making it easier for developers to focus on coding and application performance without worrying about server management.

SaaS delivers software applications over the internet, on a subscription basis. Users can access these applications via a web browser without worrying about installation or maintenance, as these tasks are handled by the service provider. This model is particularly popular for applications that require frequent updates or collaboration among multiple users.

The other options present services that are either not standard cloud service models or mix up different terms related to cloud computing, which can lead to confusion in
