Asystem's architecture is a representation of a system in which there is amapping of（71）onto hardware and softwarecomponents, a mapping of the（72）onto thehardware architecture. and a concern for the human interaction with thesecomponents. That is, system architecture is concerned with a total system, includinghardware. software, and humans.

Softwarearchitectural structures can be divided into three major categories, dependingon the broad nature of the elements they show.1）（73）embodydecisions as a set of code or data units that have to be constructed orprocured.2）（74）embody decisions as to how the systemis to be structured as set of elements that have runtime behavior. andinteractions.3）（75）embody decisions as to how thesystem will relate to nonsoftware structures in its

● For nearly ten years, the Unified Modeling Language (UML) has been the industry standard for visualizing, specifying, constructing, and documenting the （71）of a software-intensive system. As the （72）standard modeling language, the UML facilitates communication and reduces confusion among project （73）The recent standardization of UML 2.0 has further extended the language's scope and viability. Its inherent expressiveness allows users to（74)everything from enterprise information systems and distributed Web-based applications to real-time embedded systems. The UML is not limited to modeling software. In fact, it is expressive enough to model （75） systems,such as workflow in the legal system, the structure and behavior. of a patient healthcare system, software engineering in aircraft combat systems, and the design of hardware. To understand the UML, you need to form. a conceptual model of the language, and this requires learning three major elements: the UML's basic building blocks, the rules that dictate how those building blocks may be put together, and some common mechanisms that apply throughout the UML.

At a basic level, cloud computing is simply a means of delivering IT resources as （71）.Almost all IT resources can be delivered as a cloud service: applications, compute power, storage capacity, networking,programming tools,even communication services and collaboration （72）。

Cloud computing began as large-scale Internet service providers such as Google,Amazon,and others built out their infrastructure. An architecture emerged: massively scaled, （73） distributed system resources,abstracted as virtual IT services and managed as continuously configured, pooled resources. In this architecture, the data is mostly resident on （74）“somewhere on the Intemet”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 （75） 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 ofresources available —— file storage, databases, and Web services —— and extend the applicability to Web and enterprise applications.
