SaaS (Software as a Service)

refers to specialised companies who provide a very specific stack and support for that stack so as to get rid of the need for any technical headaches, e.g. where the cloud gets rid of the need for predicting growth rates (aka server purchases), SaaS gets rid of the need to maintain, update and support the specific piece of software you are running. While it does not get rid of the need for the local IT department, it does get rid of the need to call your local IT department anytime you want an update done or a bug fixed. In terms of the stack, SaaS offers technical support for all the component layers beneath it. Accordingly, In the case of Fedorazon, we have preconfigured a PaaS stack so anyone who wanted to provide the human stack component layer atop could call themselves a repository SaaS provider. Examples of SaaS: GDocs, WordPress.com, etc.
