Cloud computing developing has experienced four stages: The first stage is Voltage mode(电压模式): for example We can establish bigger power station to reduce the price of the power . People dont need to buy the generating equipment . And it is convenient for them to use the power. The second stage is Utility computing（效用计算）: Now we can build the sever in the same place not around the world . But it cant achieve in the computer developing initial period . Because the computer technology is so backward. The third stage is gird computing（网格计算/分布式计算）: The big problem is divided into many simple question . We can use some simple computer to solve the simple question .Then we can solve the big problem by the answer of the simple question It is a good idea, but it dont have the obtained the expected results. The last stage is cloud computing（云计算） : It want to us to use the IT technology to solve the problems . It can help us to save more money. Now if you want to use some software you have to buy it .but if the cloud computing technology is finished every software is for free. Why most IT teams turning to cloud computing technology to minimize the time and source ? Cloud computing consist of three part : Iaas (Infrastructure-as-a- Service/基础设施即服务 ) ,Paas (Platform-as-a- Service/平台即服务 ) ,Saas (Software-as-a- Service/软件即服务 ) . Costumer can use Internet to get their servers from the computer infrastructure . We can use the Paas to developing the software . it is a platform ,it can help you to develop the technical software . If you need to use some software you just use if from the cloud computing , you dont need to download it from the Internet. * * * * * * * Cloud ComputingIn our daily life Qian Nengwu (钱能武) 030130733 * What is cloud computing ? Everyone in the technology world is talking about it… and a lot of people in the business world are asking the same question, “What is cloud computing, and what does it mean for my busines
