What is PaaS and how does it differ from IaaS?
Platform as a service (PaaS) is a complete development and deployment environment in the cloud, with resources that enable you to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled enterprise applications. PaaS includes infrastructure such as servers, storage, and networking, but also middleware, development tools, business intelligence services, and more. IaaS only includes infrastructure resources.

How does SaaS work?
With SaaS, users connect to the software over the Internet, usually with a web browser. The service provider manages the hardware and software, and with the appropriate service agreement, will ensure the availability and the security of the app and your data.
