Starting in that decade, IBM and other mainframe providers conducted a service bureau business, often referred to as time-sharing or utility computing.
This repackaging of computing services became the foundation of the shift to "on demand" computing, software as a service and cloud computing models that further propagated the idea of computing, application and network as a service.

Cloud computing

Starting in that decade, IBM and other mainframe providers conducted a service bureau business, often referred to as time-sharing or utility computing.
IBM Cloud includes infrastructure as a service (IaaS), software as a service (SaaS) and platform as a service (PaaS) offered through public, private and hybrid cloud delivery models.

Application service provider

ASPApplication developmentapplication service
The expansion of the Internet during the 1990s brought about a new class of centralized computing, called Application Service Providers (ASP).
ASPs may or may not use multitenancy in the deployment of software to clients; some ASPs offer an instance or license to each customer (for example using Virtualization), some deploy in a single instance multi-tenant access mode, now more frequently referred to as "SaaS".

Platform as a service

With the advent of faster computers and internet connections, accounting software companies have been able to create accounting software paid for on a monthly recurring charge instead of a larger upfront license fee (software as a service - SaaS).

Web application

Whereas many initial ASPs offered more traditional client-server applications, which require installation of software on users' personal computers, SaaS solutions of today rely predominantly on the Web and only require a web browser to use.
Cloud Computing model web applications are software as a service (SaaS).

Adobe Creative Cloud Software e.g. Photoshop, Illustrator, Elements.
Shifting to a software as a service model, Adobe announced more frequent feature updates to its products and the eschewing of their traditional release cycles.

Mashup (web application hybrid)

mashupmashupsmash-up
The ubiquity of SaaS applications and other Internet services and the standardization of their API technology has spawned development of mashups, which are lightweight applications that combine data, presentation and functionality from multiple services, creating a compound service.
Another difference between business mashups and consumer mashups is a growing trend of using business mashups in commercial software as a service (SaaS) offering.

It allows companies to protect and insure all the data that resides within SaaS applications, protecting against data loss.
Business failure (vendor bankruptcy), where data is stored with a software vendor using Software-as-a-service and SaaS data escrow has not been provisioned.

Drupal

Drupal 7Drupal CMSOpenAtrium
The term was coined in 2011 by Dries Buytaert, creator of the Drupal content management framework.
The Drupal core search is ineffective at searching content: There are contributed modules that will greatly improve the search functionality on a Drupal website, but they are not easily accessible due to a high learning curve and the difficulty users have in general of finding the right module. One of the faceted search options is Apache Solr Search Integration module, however, the module requires a dedicated server or virtual private server (VPS) to operate because Solr must run on a servlet container, e.g. Tomcat, Jetty or Resin. These requirements make it harder for a Drupal website to have a functional search feature. In response some companies have created Apache Solr SaaS products.

Laravel

Laravel 5Laravel Framework
The standardization of web page technologies (HTML, JavaScript, CSS), the increasing popularity of web development as a practice, and the introduction and ubiquity of web application frameworks like Ruby on Rails or Laravel (PHP) gradually reduced the cost of developing new SaaS solutions, and enabled new solution providers to come up with competitive solutions, challenging traditional vendors.
The package was developed by Taylor Otwell and provides additional tools for online SaaS businesses to integrate with services like Stripe, Producing invoices, Bootstrap 4.0, and team authentication.

Richard Stallman

Richard M. StallmanStallman Stallman, Richard
One notable criticism of SaaS comes from Richard Stallman of the Free Software Foundation referring to it as Service as a Software Substitute (SaaSS).
Stallman has suggested that the United States government may encourage the use of software as a service because this would allow them to access users' data without needing a search warrant.
