Detailed explanation-1: -PaaS is most often built on top of an IaaS platform to reduce the need for system administration. It allows you to focus on app development instead of infrastructure management. SaaS offers ready-to-use, out-of-the-box solutions that meet a particular business need (such as a website or email).
Detailed explanation-2: -There are 3 main types of cloud computing as-a-service options and each one covers a degree of management for you: infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), and software-as-a-service (SaaS).
Detailed explanation-3: -In a nutshell, IaaS provides access to resources such as virtual machines and virtual storage, PaaS provides execution environments, application development, and deployment tools, and SaaS provides software as a service to end-users.
Detailed explanation-4: -Unlike the IaaS model, PaaS providers manage runtime, middleware, and operating systems. However, PaaS customers still get to manage data and applications-in contrast to the SaaS model, where customers don’t have to manage anything. So in terms of the cloud continuum, PaaS fits snugly between IaaS and SaaS.
