Cloud Computing, often referred to as “stack”, is classified by most common service models, SaaS, PaaS and IaaS.
IaaS(Infrastructure as a service), the base layer, provides you the computing infrastructure, physical or (quite often) virtual machines and other resources. Amazon EC2 is one of them.
Paas, a layer on top of IAAS, provides you computing platforms which typically includes operating system, database, web servers and such, popular among developers to “build” apps not worrying about the base layer. The popular service includes Google App Engine, Windows Azure and such.
While SaaS, more popular among with consumers, provides access to application softwares often referred to as on-demand softwares. You don’t have to worry about the installation, setup, you can just “consume” the application, such as Google Apps.
Parallels made their service classification which matters to SMBs: IaaS, web presence and web applications, hosted communication and collaboration, and a general category (they refer to as business applications).
