- Infrastructure as a Service, or IaaS, is a service model that provides machine level
resources to the user. The "infrastructure" consists of configurable storage,
network connectivity, processing power, and a basic operating system image. The user then
can configure the operating system to suit their needs, without the overhead required for
management of the hardware and virtualization technology the operating system runs on.

<para>
- With the Platform as a Service, or Paas, service model, even more of the resources are
provided as a service. The "platform" includes computing resources, a configured
operating system, and services and software required by the user's application. The
user is then only responsible for their application. For example, a mediawiki deployment
would include PHP, a database server, a web server, and mediawiki itself, all
preconfigured. The user then only has to take care of administrative work, like defining
policies and user roles or populating the wiki with content.

configuration and management of the application. The user primarily acts as a consumer of
