让计算能力像水和电一样作为一项公共事业随时提供给用户是云计算最初的思想起源。2007年“云计算”概念诞生,5年后的今天,这个概念已开始逐步“落地”转向应用。但因尚处发展初期,云计算领域还面临不少问题。在12月3—4日举行的“2012国际云计算大会”上,专家指出在云计算领域,统一标准尚未形成、数据中心重复建设、核心技术尚未突破、缺乏强有力的带动性应用,以及安全标准缺乏等多个问题都是今后发展需要跨越的障碍。 Making computing power available to users as a utility at a time like water and electricity is the initial source of thought for cloud computing. In 2007 “cloud computing ” concept was born, 5 years later, this concept has begun to “landing ” shift to application. However, due to the initial development, the cloud computing is still facing many problems. At the “2012 International Cloud Computing Conference” held on December 3-4, experts pointed out that in the field of cloud computing, uniform standards have not yet been formed, data center construction is repeated, core technologies have not yet been exceeded, and there is a lack of strong and leading applications. As well as the lack of safety standards and other issues are the obstacles that need to be overcome in the future development.
