Understanding SaaS: Origins, Evolution, and Key Examples

Introduction to the Concept of SaaS

The term Software as a Service (SaaS) refers to a software service accessible via the Internet. This model allows users to access applications without needing to install them locally.

The Roots of SaaS

The concept's origins date back to the 1960s with the time-sharing initiative, primarily developed by IBM. At the time, owning a computer was expensive and limited to large institutions such as governments or universities.

Evolution to ASP and the Birth of the SaaS Term

In the 1990s, the term Application Service Providers (ASP) emerged, with SAP as a leader in this domain. The true rise, however, began in the late 1990s with pioneers like Salesforce offering innovative solutions for customer relationship management.

The Expansion and Diversification of the SaaS Model

Various Services in Software Form

With technological advancements from the early 2000s to today, many services based on the SaaS model have emerged:

• Google Workspace, including Google Docs and Gmail.
• Microsoft 365, enabling access to Office directly from a browser.

These platforms provide enhanced accessibility without requiring specific hardware to be installed locally.

Other Important Forms: UCaaS, CCaaS...

Among these diversified models are:

• UCaaS (Unified Communication as a Service): Facilitates intra-company communication through Slack or Microsoft Teams.
• CCaaS (Contact Center as a Service): Manages customer interactions via IP telephony services provided by Ringover or Genesys.

Each offers unique benefits while using the Internet as the central platform.
