Cloud computing is a phrase used to describe a variety of computing concepts that involve a large number of computers _(请作答此空71)__ through a real-time communication network such as the Internet. In science, cloud computing is a _(请作答此空72)__ for distributed computing over a network, and means the _(请作答此空73)_ 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 _(请作答此空74)__ for building the platform layer of the cloud. In turn, the platform layer is foundation for implementing the _(请作答此空75)__ layer for SaaS application.

表示有关的,有联系的意思。
云计算是一个用来描述各种计算概念的一个短语,计算概念涉及大量的计算机通过实时通信的网络,如Internet,连接在一起。在科学研究中,云计算是分布式网络计算的同义词,意味着有能力同时在多台互连的计算机上运行一个程序或应用。
云的结构分为3层:基础设施、平台和应用。基础实施层由虚拟计算机存储和网络资源构成;平台层是具有通用性和复用性的软件资源的集合;应用层是云上针对SaaS应用的所有应用软件的集合。基础设施层时建立平台层的硬件基础;相应地,平台层是执行应用层SaaS应用的基础。作者: 郭小贱 时间: 2020-9-21 14:53
