People mean a lot of things when they talk about "the cloud," but if you want to know where the revenue is going, look no further than SaaS (software as a service). Salesforce leads the SaaS pack with $2 billion in revenue for its latest fiscal year. NetSuite pulled in just a tenth of that for FY2010, but in some ways it's a more ambitious player, because it offers ERP as a service -- a core enterprise software category that, in the past, has been last on the list to trust to the cloud.
Zach Nelson, CEO of NetSuite, thinks that reluctance has been replaced by enthusiasm for the quick deployment, continuous innovation, and low maintenance of SaaS. A former executive at Oracle, Sun Microsystems, and Network Associates, Nelson joined NetSuite as CEO in 2002. Between then and now he has witnessed the industry's long, slow ramp-up to today's feverish interest in all things cloud -- an environment he sees as ripe to capture a new wave of customers.
