Worldwide software as a service (SaaS) revenue within the enterprise application software market is forecast to surpass $8.5bn in 2010, up 14.1 percent from 2009 revenue of $7.5bn, according to information technology research and advisory firm Gartner.
The IT researcher said that the rapid adoption of SaaS has contributed to growth in varying degrees across the enterprise software markets and there will be a shift in total SaaS revenue from just over 10 percent of the combined markets in 2009, to more than 16 percent of these combined markets in 2014.
Gartner estimates that 75 percent of the current SaaS delivery revenue could be considered as a cloud service, and that could exceed 90 percent by 2014 as the SaaS model matures and converges with cloud services models.
