Small businesses, which have no budget for a big technology department, are especially eager to take advantage of the cheap computer power offered in the cloud.

Hilliard's Beer in Seattle, founded in October 2011, bought software from the German company SAP that allows it to use cloud computing to track sales and inventory and to produce the reports that federal regulators require.

"It automates a lot of the stuff that we do," owner Ryan Hilliard says. "I know what it takes to run a server. I didn't want to hire an IT guy."

And the brewery keeps finding new ways to use the beefed-up computing power. For example, it's now tracking what happens to the kegs it delivers to restaurants and retrieving them sooner for reuse. "Kegs are a pretty big expense for a small brewery," Hilliard says.

Automated Insights in Durham, N.C., draws on the computing power of the cloud to produce automated sports stories, such as customized weekly summaries for fantasy football leagues. "We're able to create over 1,000 pieces of content per second at a very cost-effective rate," says founder Robbie Allen. He says his startup would not have been possible without cloud computing.

SMARTER MACHINES

Though many are still working out the kinks, software is making machines and devices smarter every year. They can learn your habits, recognize your voice, do the things that travel agents, secretaries and interpreters have traditionally done.

Microsoft has unveiled a system that can translate what you say into Mandarin and play it back â¿¿ in your voice. The Google Now personal assistant can tell you if there's a traffic jam on your regular route home and suggest an alternative. Talk to Apple's Siri and she can reschedule an appointment. IBM's Watson supercomputer can field an awkwardly worded question, figure out what you're trying to ask, retrieve the answer and spit it out fast enough to beat human champions on the TV quiz show "Jeopardy!" Computers with that much brainpower increasingly will invade traditional office work.
