Computing in the clouds

The idea is simple: Instead of keeping your programs and data on a local computer or server in your home or office, let someone else store and manage the material for you in the "cloud": remote servers kept in multiple locations throughout the country.
Data backup is just one use of the cloud. Companies large and small are realizing that they can ditch their in-house servers and let other people store and manage their e-mail, and even their favorite software, from anywhere in the world. Many are now using cloud versions of e-mail, word-processing, spreadsheet, calendar and presentation software.
By utilizing cloud computing services, there’s less need for an IT department. Cloud computing is growing as high speed broadband connections become widespread, making fast data transfer feasible. When colleagues need to revise a document, everyone can use their Web browser to view it in the cloud and make necessary changes, all on the same copy.
But what about security? Many consumers raise questions about how safe their personal information is, given recent accounts of hackers obtaining Social Security numbers, breaking into banks and more. Cloud computing service providers respond that steps are taken to ensure safety – typically several layers of protection. And customers’ files are usually kept encrypted, safe from prying eyes.
By cutting IT costs and by not needing to continually upgrade both software and local servers, cloud computing can also be a bargain for many small businesses.
