The different cloud delivery models include Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). SaaS provides ready-to-use applications accessible via the internet, eliminating the need for users to install or manage software, with examples like Google Workspace and Salesforce. PaaS offers a platform allowing developers to build, deploy, and manage applications without worrying about the underlying infrastructure, exemplified by services like Microsoft Azure and Google App Engine. IaaS delivers virtualized computing resources over the internet, such as servers, storage, and networking, enabling businesses to rent infrastructure on a pay-as-you-go basis; prominent examples include Amazon Web Services (AWS) and IBM Cloud. Each model provides different levels of control, flexibility, and management, catering to varying business needs and technical requirements.

The term cloud delivery model refers to how cloud services are provided to users. There are three primary models: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Each model offers different levels of control, flexibility, and management to meet various business needs.

In the SaaS Model, software applications are delivered over the internet on a subscription basis, allowing users to access them through web browsers without the need for local installation. The service provider takes care of the underlying infrastructure and platforms, making it a user-friendly option. Examples of SaaS include productivity suites like Google Workspace and customer relationship management systems like Salesforce.

On the other hand, the PaaS Model provides a cloud platform with tools that help developers build and deploy applications efficiently. It simplifies the process by managing the infrastructure, allowing users to focus on application development and data management. Meanwhile, the IaaS Model provides virtualized computing resources over the Internet with a pay-as-you-go model. It gives users automated and scalable environments, along with complete control over their computing resources, exemplified by services like Amazon Web Services and Microsoft Azure.

These delivery models offer varying levels of control and management, catering to diverse business requirements and technical needs. In addition to these primary cloud delivery models, there are other models such as Function as a Service (FaaS), Container as a Service (CaaS), and Database as a Service (DBaaS). These provide specialized services catering to specific needs within the cloud computing ecosystem, offering more options for organizations to optimize their operations.
