The History of SaaS

Software as a Service (SaaS) represents a relatively contemporary concept in software delivery, although its roots trace back to the mainframe era of computing in the 1960s and 1970s, where computer terminals were utilized to access mainframes hosting software applications.

Nonetheless, the contemporary SaaS model, as recognized today, did not crystallize until the late 1990s and early 2000s, coinciding with the widespread accessibility and reliability of the internet. This technological advancement facilitated the delivery of software applications over the web, laying the groundwork for the SaaS delivery model.

The earliest known SaaS applications were rudimentary web-based tools like email, customer relationship management (CRM), and project management software. These applications were architected for access through web browsers, obviating the necessity for users to install and maintain software on their local machines.

One of the pioneering examples of a SaaS application was Salesforce, introduced in 1999. Salesforce provided a web-based CRM solution empowering businesses to manage customer relationships more efficiently and with enhanced scalability. Several other early SaaS apps were WebEx (1995), which introduced the first version of online conferencing software, and NetSuite (1998), which provided ERP and accounting software.

Early SaaS applications encountered various challenges, such as sluggish internet speeds and limited bandwidth. Nonetheless, these impediments were gradually surmounted as internet infrastructure evolved and more enterprises embraced the SaaS model.

The ascendancy of the SaaS operational paradigm has persisted since the early 2000s, fueled in part by the emergence of cloud computing. Progresses in cloud computing facilitated the delivery of software applications over the internet utilizing remote servers, substantially mitigating the cost and complexity associated with deploying and managing SaaS applications.

The enduring prominence of the SaaS operational paradigm has been propelled by several factors. Below, we delineate some of the key developments in the SaaS landscape over the past decade:
