Gartner is reporting that SaaS revenue will reach $12.1 billion in 2011. 63.6 percent of all worldwide SaaS usage [in 2011] is expected to be in North America.
It was interesting to see that the issue related to SaaS varies by region
- EMEA - Limited flexibility of customization.
- North America / Asia - Limited integration with existing systems.
"In North America, ease and speed of deployment are primary reasons for SaaS adoption, followed by lower TCO," Ms. Mertz said. "Limited capital expense is also considered more important in North America than in the other regions. Consistent with the other regions, CRM shows the highest use of SaaS among enterprise applications while use of Web conferencing, e-learning and travel booking is higher in North America than in the other regions."
