从从大型机到客户机-服务器系统的转换开始，后来随着电子商务和J2EE的出现，大型企业主要迁移到高度基于网络的分布式网络计算环境中，该环境具有防火墙和非军事区。目前，大多数应用程序都有web前端，看看这些应用程序的部署架构，在网络环境中通常会发现三个不同的层:web表示层、业务逻辑或应用程序层和后端数据存储层。在共享的公共基础设施环境中部署和承载应用程序是一种常见的做法。因此，记录在开发和生产环境中支持应用程序的逻辑应用程序和技术组件(例如，服务器)之间的映射变得非常关键。网络计算硬件图的目的是显示分布式网络计算环境中逻辑应用程序组件的部署逻辑视图。

UML/BPMN  EAP Profile 

Server device: Represents a hardware platform, that can be connected to other devices, and on which application components are deployed.

Workstation: Workstations are connected via network links to the IS. Application components can be deployed there.

Process application component: A process application component is responsible for a business process execution. It orchestrates the tasks of the process.

Entity application component: An entity component is frequently derived from business entities, and is responsible for managing the access to the entity, and its integrity.

Utility component: Represents an application component that is frequently reused, and most of the cases bought off the shelf.

Interaction application component: Represents the top level components that manage the interaction with elements outside the IS. In most cases, it is a GUI component, such as here a web interface.

Database application component: This represents a repository. In pure SOA architecture, these elements should not appear. However, for legacy analysis or technology architecture, modeling repositories or repository deployment can be useful.

Application: This application component corresponds to legacy applications, off the shelf products, or can be an assembly of application components.

Internal actor: An actor that belongs to the enterprise

Association between two classes: An association has a name, and for each extremity provides the role name and cardinalities (possible number of occurrences) of related elements.

此图显示了应用程序组件部署的位置、计算机如何联网，等等。

此图展示了通过网络互连的硬件(服务器、工作站)，以及部署在此硬件上的技术和应用程序组件。

技术、体系结构组件(如web服务器)被添加到应用程序体系结构中标识的逻辑组件中。
