Gartner's press release of the SaaS survey mentions that TCO, ease of integration and technical requirements are challenges faced by SaaS solutions. No surprise. And that is why when I look at the most successful SaaS company in the planet I can understand that success is never a coincidence. Salesforce.com's is a true role model for Cloud Computing and SaaS startups. Ten years ago they understood the importance of technology integrity, innovation and excellent customer service.
When it comes to the future, I prefer to focus on the ones that are shaping it and not just talking about it.
