In an IaaS model, a third-party provider hosts hardware, software, servers, storage and other infrastructure components on behalf of its users.
IaaS providers also host users' applications and handle tasks including system maintenance, backup and resiliency planning.http://searchcloudcomputing.techtarget.com/definition/Infrastructure-as-a-Service-IaaS
The cloud service model in which a user is provided with the hardware and software needed to develop and offer applications via the Internet is known as Platform as a Service (PaaS).
PaaS provides a platform to developers for building, deploying, and managing applications, without the need for infrastructure management. This model provides users with a complete software development environment, including hardware, operating system, and middleware, which enables developers to build and test applications. PaaS typically includes tools for application design, development, testing, deployment, and hosting.
On the other hand, Infrastructure as a Service (IaaS) provides virtualized computing resources, such as virtual machines, storage, and networking, over the Internet. With IaaS, users have more control over the operating system, middleware, and applications they choose to deploy. IaaS provides a virtualized infrastructure, on top of which users can install and configure their own software.
Software as a Service (SaaS) provides software applications over the Internet, without the need for installation or maintenance. SaaS delivers applications as a service, eliminating the need for users to install, maintain, and upgrade software on their own computers.
Applications as a Service is not a commonly used cloud service model. However, it can be considered a subcategory of SaaS, where applications are offered as a service, but with a focus on specific functionality, rather than providing a complete software suite.
In summary, when a user is provided with the hardware and software needed to develop and offer applications via the Internet, the user is consuming a Platform as a Service (PaaS) cloud model.
