This is true even within single applications. Yahoo mandates PHP at the surface, but uses C++ for most back-ends because they need to handle a few billion page views per day. Amazon too has lots of core computations in C++ (and even Java), yet uses Perl and Mason for the front end. A reasonable division of labour at the biggest sites on the internet.

本文探讨了大型互联网公司如Yahoo和Amazon在其应用中如何选择合适的技术栈。Yahoo使用PHP作为前端,而核心后端则采用C++以应对每天数十亿的页面浏览量。Amazon同样在前端使用Perl和Mason,在后端进行核心计算时选择了C++和Java。
