在消息传递中间件中，通过使用一个名为消息代理(或队列管理程序)的服务器组件以消息的形式在系统间传递数据来实现连接。
In messaging middleware, connectivity is achieved by passing data between systems through a server component known as a message broker (or a queue manager) in the form of messages.
在中间件层边缘(我们将边缘视为层次间转换发生的地点)，很可能会存在其他组件，如代理服务器等。
At the edge of the middleware tier (an edge is considered as a point where transition from one tier to another takes place), there are most likely found other components, such as proxy servers.
为提供者服务安装并配置了中间件代理后，可以将其用于集成任意数量的Web服务使用者，而无需进行任何额外的工作。
After the middleware proxy has been installed and configured with a provider service, it can be used to integrate any number of Web service consumers with no additional effort.
Web服务提供者和使用者应用程序无需更改就可以通过中间件代理进行互操作。

由于数字化的资产被定义为中间件的构件(artifact)，所以它们可以与其他流程代理程序服务一起进行操作(在一个事务处理中)。
Since the digital assets are defined as an artifact of the middleware, they can be manipulated in conjunction with other Process Broker services, under a single transaction.
Logging：此视图提供了一个集中式用户界面，此界面包含每个VM的特定于操作系统、特定于中间件和特定于Workload Deployer代理的日志的集合。
Logging: This view provides a centralized user interface with a collection of OS-specific, middleware-specific, and Workload Deployer agent-specific logs for each VM.
与EJB代理方法和中间件代理方法不同的是，此方法没有性能影响。
And unlike either the EJB proxy approach or the middleware proxy approach, this approach has no performance impact.
请继续关注本系列的后续文章，我们将在其中提供有关如何实现中间件代理和EJB代理解决方法的细节和示例。
Stay tuned for subsequent articles in this series, which will provide details and examples that show you how to implement the middleware proxy and EJB proxy workarounds.
例如，是否有必要通过类似于代理的中间件系统来把客户端身份传递到服务实现的最终提供者？
For example, is there a need to propagate client identity through intermediate systems such as brokers to the end-providers of service implementations?
与本系列以前的文章中所述的中间件代理方法相比，实现EJB代理方法只是基本的编程做法。
Compared to the middleware proxy approach described in a previous article of this series, implementing the EJB proxy approach is a basic programming exercise.
如果要寻找轻量的低成本备选方案来替代中间件代理方法，使用EJB代理可能比较合适。
If you're looking for a lightweight, low-cost alternative to the middleware proxy approach, using an EJB proxy might be suitable.
中间件分数据库、远程过程调用、面向消息、对象请求代理、事务处理管程(TPM)或专用(PM)等类。
The middleware is divided into some classes, such as database, remote procedure call (RPC), oriented message, object request agent, transaction processing management (TPM) or special PM.
CORBA就是一种用于简化分布式应用程序和服务开发的对象请求代理(orb)的中间件标准。
CORBA is an emerging middleware standard for Object Request Brokers (ORBs) that simplifies the development of distributed applications and services.
该架构的核心是一个中间件，文中称该中间件为CORBA代理。
The core of the architecture is a middleware that is named the CORBA Proxy.
