At a basic level,cloud computing is simply a means of delivering IT resources as( ).Almost all IT resources can be delivered as a cloud service:applications,compute power,storage capacity,networking,Programming tools,even communication services and collaboration( ).Cloud computing began as large-scale Internet service providers such as Google,Amazon,and others built out their infrastructure.An architecture emerged:massively scaled,( )distributed system resources,abstracted as virtual IT services and managed as continuously configured,pooled resources.In this architecture,the data is mostly resident on( )"somewhere on the Internet"and the application runs on both the"cloud servers"and the user's browser.Both clouds and grids are built to scale horizontally very efficiently.Both are built to withstand failures of( )elements or nodes.Both are charged on a per-use basis.But while grids typically process batch jobs,with a defined start and end point,cloud services can be continuous.What's more,clouds expand the types of resources available-file storage,databases,and Web services-and extend the applicability to Web and enterprise applications.问题1选项A.hardwareB.computersC.servicesD.software问题2选项A.computersB.disksC.machinesD.tools问题3选项A.horizontallyB.verticallyC.inclinedD.decreasingly问题4选项A.clientsB.middlewareC.serversD.hard disk问题5选项A.entireB.individualC.generalD.separate

解析
基本上,云计算仅仅意味着将IT资源作为服务来提供。几乎所有的IT资源都可以作为一个云服务来提供:如应用程序,计算能力,存储容量,网络,编程工具,甚至通讯服务和协作工具。
开始大规模提供云计算的互联网服务提供商有谷歌,亚马逊和其他一些基础建设商。云架构的特点是:系统不断扩大,水平分布系统资源,抽象的虚拟服务和管理,然后不断配置,汇集资源。在这种体系结构中,数据主要存放在“互联网某处”的服务器和“云服务”与客户端运行的应用程序上。
要想建立一个能收取使用费的云网格,必须要建立经得起单个元素或节点失败的云网格。当用网格来处理一批日常工作时,需要定义一个明确的开始和结束点,云服务可以是连续的。但更重要的是,云可以扩展可用的文件存储,数据库,网络服务来适用于网络和企业应用。
