New Signature, a Washington, D.C., solution provider, said one of the secrets to succeeding in the cloud era is developing a robust application development business. Among the compelling Web services applications developed by New Signature are Votifi.com, allowing voters to exchange ideas and vote on specific issues, and ioby.org, a micro-funding services site aimed at allowing local eco-friendly projects to get funding. Christopher Hertz, founder and CEO of New Signature, predicts that the company's application development business will grow from 25 percent of sales in 2012 to 45 percent of sales in 2018. "The opportunity in this new cloud services ecosystem is no longer around building infrastructure," said Hertz. "It is around building applications."
