I will directly get to the point. (I am a good samaritan 😉)
IaaS (Infrastructure as a Service): It refers to a cloud computing model where the fundamental infrastructure resources, such as servers, storage, and networking, are provided as a service. With IaaS, users have control over their operating systems and applications, while the cloud provider manages the underlying infrastructure.
PaaS (Platform as a Service): PaaS is a cloud computing model that provides a platform for developing, running, and managing applications. It offers a complete development environment, including operating systems, programming languages, libraries, and tools. PaaS abstracts the underlying infrastructure, enabling developers to focus on application development rather than managing hardware or software infrastructure.
FaaS (Function as a Service): FaaS is a cloud computing model where developers can execute functions or code snippets without the need to manage the underlying infrastructure. Developers can write and deploy individual functions that are triggered by events or requests. FaaS abstracts away the server management aspects, allowing developers to focus solely on writing the code for specific functions.
SaaS (Software as a Service): SaaS is a cloud computing model where software applications are delivered over the internet as a service. Users can access and use the software through a web browser or a thin client, without the need for installation or local hardware resources. SaaS providers handle all aspects of software maintenance and infrastructure management.
