Software as a Service has been at the vanguard of cloud adoption, with Salesforce.com(s crm) starting to blaze the trail more than a decade ago and Workday, Okta, Zoho and other players following behind. But growth for SaaS shows no sign of slowing, according to new research from North Bridge Venture Partners working with Gigaom Research.

Among 1,348 respondents surveyed, SaaS adoption grew five-fold from 11 percent to 74 percent in the four years that North Bridge started running Future of Cloud Computing Survey, said Michael Skok, general partner of North Bridge Venture Partners. Of the total field surveyed, 43 percent of which were cloud users ,57 percent were tech vendors. Skok will talk more on the findings thursday at Structure.

North Bridge also found that more than half (56 percent) are using Infastructure as a Service, and 41 percent are using Platform as a Serivce to build new applications
