A MapReduce application or a web crawler application fits perfectly with this model.

典型的如MapReduce框架，或者一个web crawler应用都很适合这个模型。

Here are a few simple examples of interesting programs that can be easily expressed as MapReduce computations.

下面是一些mapreduce应用中有趣的例子。

The example here goes with the canonical MapReduce application, but you'll see other applications later (along with how you would implement them in map and reduce form).

虽然此处的示例伴随着规范的MapReduce应用程序，但是稍后您将看到其他的应用程序（取决于您将如何用map和reduce格式实现它们）。
