什么是中间件？ [英] What is middleware exactly?

问题描述

我听到很多人最近在谈论有关中间件的问题，但中间件的确切定义是什么？当我研究中间件时，我发现了很多信息和一些定义，但在阅读这些信息和定义时，似乎大多数商品都处于某种东西的中间。那么，所有东西都是中间件吗？

或者你有没有中间件的例子？

解决方案

可以说你的公司生产4种不同的产品，你的客户有另外3种不同的公司生产的另外3种不同的产品。

客户想，为什么我们不把所有的系统集成到一个庞大的系统中。 10分钟后，他们的IT部门表示这将需要2年时间。你（聪明的开发人员）说，为什么我们不把所有不同的系统集成在一起，让他们在同质环境中一起工作？客户经理盯着你......你继续说，我们将使用一个中间件，我们将研究所有不同系统的输入/输出，他们使用的资源，然后选择一个合适的中间件框架。

仍然向非技术经理解释

在中间件框架的中间，第一个系统会产生X stuff ，系统Y和Z会消耗那些输出等等。

I have heard a lot of people talking recently about middleware, but what is the exact definition of middleware? When I look into middleware, I find a lot of information and some definitions, but while reading these information and definitions, it seems that mostly all 'wares' are in the middle of something. So, are all things middleware?

Or do you have an example of a ware that isn't middleware?

解决方案

Lets say your company makes 4 different products, your client has another 3 different products from another 3 different companies.

Someday the client thought, why don't we integrate all our systems into one huge system. Ten minutes later their IT department said that will take 2 years.

You (the wise developer) said, why don't we just integrate all the different systems and make them work together in a homogeneous environment? The client manager staring at you... You continued, we will use a Middleware, we will study the Inputs/Outputs of all different systems, the resources they use and then choose an appropriate Middleware framework.

Still explaining to the non tech manager
With Middleware framework in the middle, the first system will produce X stuff, the system Y and Z would consume those outputs and so on.
