Software-as-a-service (SaaS) is a growing cloud model. If we were talking literal clouds, SaaS would probably be a cumulonimbus at this point, as 82 percent of today’s cloud investments are SaaS with 84 percent intending to use SaaS to deploy new applications. This information comes from an infographic on display at TechRepublic, which covers the history and future of SaaS. Among other things, it teaches that it was in 1999 that the first SaaS was built that achieved rapid growth, called Salesforce, though the term “SaaS” was apparently not coined until 2001. The current key drivers of SaaS include broadband, mobile, Internet security improvements, browser improvements, and APIs. The various applications of SaaS include customer support, analytics, business intelligence, software development and testing, and procurement. Moving forward, SaaS will inevitably be incorporated further into how companies handle social media and big data.
