According to market research firm Gartner, worldwide software as a service (SaaS) revenue is on pace to reach $7.5 billion in 2009. That's a big turnaround from 2008 -- 17.7 percent, to be exact -- when revenue fell flat at $6.4 billion.
"The adoption of SaaS continues to grow and evolve within the enterprise application markets," said Sharon Mertz, research director at Gartner. "The composition of the worldwide SaaS landscape is evolving as vendors continue to extend regionally, increase penetration within existing accounts and ‘greenfield’ opportunities, and offer more-vertical-specific solutions as part of their service portfolio or through partners."
But that's not the only good news. Gartner says the market will show consistent growth at least through 2013, by which time SaaS revenue is expected to exceed $14 billion in the enterprise sector.
