Cloud Computing Service Models

Cloud computing service models refer to the different ways that cloud computing services are offered to users. There are three main service models:

• Infrastructure as a Service (IaaS)

IaaS is the most basic service model, and it provides users with virtualized computing resources over the internet. This includes servers, storage, and networking components. Users can deploy and manage their own applications and operating systems on these virtualized resources.

• Platform as a Service (PaaS)

PaaS is a level above IaaS, and it provides users with a platform for running their applications. This includes an operating system, programming language execution environment, database, and web server. Users can focus on developing and deploying their applications without worrying about managing the underlying infrastructure.

• Software as a Service (SaaS)

SaaS is the most complete service model, and it provides users with access to software applications over the internet. The applications are hosted on a cloud provider's servers and are accessed through a web browser or other client application. Users do not have to manage the infrastructure or the software, and they can simply use the applications provided by the cloud provider.
