What is the History of Cloud Software?

History

The concept of "software as a service" started to circulate prior to 1999 and was considered to be "gaining acceptance in the marketplace" in Bennett et al., 1999 paper on "Service Based Software".

Whilst the term "software as a service" was in common use, the CamelCase acronym "SaaS" was allegedly not coined until several years later in a white paper called "Strategic Backgrounder: Software as a Service" by the Software & Information Industry's eBusiness Division published in Feb. 2001, but written in fall of 2000 according to internal Association records.

Philosophy

As a term, SaaS is generally associated with business software and is typically thought of as a low-cost way for businesses to obtain the same benefits of commercially licensed, internally operated software without the associated complexity and high initial cost. Many types of software are well suited to the SaaS model, where customers may have little interest or capability in software deployment, but do have substantial computing needs. Application areas such as Customer relationship management (CRM), video conferencing, human resources, IT service management, accounting, IT security, web analytics, web content management and e-mail are some of the initial markets showing SaaS success. The distinction between SaaS and earlier applications delivered over the Internet is that SaaS solutions were developed specifically to leverage web technologies such as the browser, thereby making them web-native. The data design and architecture of SaaS applications are specifically built with a 'multi-tenant' backend, thus enabling multiple customers or users to access a shared data model. This further differentiates SaaS from client/server or 'ASP' (Application Service Provider) solutions in that SaaS providers are leveraging enormous economies of scale in the deployment, management, support and through the Software Development Lifecycle.
