PaaS Business Model - FourWeekMBA

PaaS stands for the platform as a service. Together with other “as-a-service” models, this model’s basic premise is to offer a solution to the final customer without having to host it on-premise, with complex implementations and large overhead. The PaaS model is a form of evolved cloud computing. The provider, together with virtualization, storage, network, and servers, provides middleware and runtime to the user/customer, which only handles data and applications.

Aspect	Explanation

PaaS applications and examples

In the PaaS model, the platform that enables the applications’ development is handled by the PaaS provider, where the final user/customer (usually development teams) will handle the application and data itself.

Therefore, the PaaS provides a platform where users can develop and deploy their own applications, with the advantage of an agile infrastructure, not hosted on-premise, and therefore faster to implement and more flexible.

Some PaaS providers also include Microsoft Azure, Google Cloud, Amazon AWS, IBM Cloud, where together with the cloud infrastructure (IaaS), the platform to develop and deploy applications on top of the cloud is offered.

This makes it possible for the user/customer of the PaaS provider to only focus on developing and deploying applications, rather than developing the whole infrastructure.
