It’ll be interesting to see if Google and Salesforce.com can respond to this assertion with substantive customer data
Microsoft developer and platform general manager Matt Thompson has claimed that among startups across the United States, interest in Google's App Engine is "almost nonexistent" and that only a "tiny number" have an eye on Salesforce's Force.com. Citing a recent Microsoft survey, Thompson said that if startups are interested in building and deploying apps on a so-called public cloud, they're interested in Amazon Web Services and, yes, Microsoft Azure.
"Salesforce has built a huge business. [It's] very successful," he said. "But if you go to the leading startups who are building apps today, Salesforce is an edge case. We see [interest in] Amazon [EC2], host-your-own setups, and Azure. Those are the top three."
