As for the providers of cloud applications, this model simplifies their work with
respect to upgrading and testing the code, while protecting their intellectual property.
Since a cloud application is deployed at the provider’s computing infrastructure
(rather than at the users’ desktop machines), the developers of the application
are able to roll smaller patches to the system and add new features without disturbing
the users with requests to install updates or service packs. The configuration
and testing of the application in this model is arguably less complicated, since the
deployment environment, i.e., the provider’s data center becomes restricted. Even
with respect to the provider’s profit margin, this model supplies the software provider
with a continuous flow of revenue, which might be even more profitable on
the long run. This SaaS model conveys several favorable benefits for the users and
providers of the cloud application. The body of research on SOA has numerous
studies on composable IT services, which have a direct application to providing
and composing SaaS.
