1、Cloud computing is a phrase used to describe a variety of computing concepts that involve a large number of computers （ ）through a real-time communication network such as the Internet．In science，cloud computing is a （ ）for distributed computing over a network，and means the （请作答此空）to run a program or application on many connected computers at the same time．The architecture of a cloud is developed at three layers： infrastructure，platform，and application，The infrastructure layer is built with virtualized compute，storage，and network resources．The platform layer is for general-purpose and repeated usage of the collection of software resources．The application layer is formed with a collection of all needed software modules for SaaS applications．The infrastructure layer serves as the（ ）for building the platform layer of the cloud． In turn，the platform layer is a foundation for implementing the（ ）layer for SaaS applications．
A、ability
B、applroach
C、function
D、method

答案:A
答题解析:

云计算是用来描述各种计算概念的短语，包括大量计算机通过网络相互连接以实现分布计算，意思是同时在很多互联的计算机上运行程序或应用的能力。

云的架构分为基础设施层、平台层和应用层三层。基础设施层由虚拟计算、存储和网络资源构成。平台层用于一组软件资源重复使用的通用目的。应用层由一组所需的软件模块构成，即软件即服务（SaaS)。基础设施层作为构建平台层的基础。相反，平台层是应用层的基础，为SaaS应用实现应用层。
