摘 要：Cloud computing is fast becoming an integral part of how we communicate with one another, buy music, share photos, conduct business, pay our bills, shop, and bank. Many of the activities that once occurred solely in the physical world, including communications with one another, are increasingly moving to the digital world. What was once a letter to a friend is now a Facebook message; a call to a loved one is now a Skype chat; a private meeting with a business partner is now a video conference call. In short, the cloud is revolutionizing not only how we compute, but also how we live. Where individuals once locked personal or business papers solely in a desk drawer or filing cabinet, they now also store them on someone elses computer. In short, cloud computing is a web-based service that allows users to access anything from e-mail to social media on a third-party computer.
