Infrastructure as a Service (IaaS)

IaaS is the most basic type of cloud computing service, where the cloud provider offers virtualized computing resources, such as servers, storage, and networking, as a service over the internet. The user has complete control over the operating system, applications, and middleware, but is responsible for managing the virtual machines and the applications running on them. Examples of IaaS providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform.

Platform as a Service (PaaS)

PaaS is a cloud computing service that provides a platform for developers to build and deploy applications without having to worry about the underlying infrastructure. The cloud provider offers a set of pre-built tools, such as programming languages, application servers, and databases, that developers can use to build and deploy their applications. Examples of PaaS providers include Heroku, Google App Engine, and Microsoft Azure.

Software as a Service (SaaS)

SaaS is a cloud computing service that provides software applications over the internet. The cloud provider hosts the software and makes it available to users as a service, eliminating the need for users to install and maintain the software on their own computers.
