Instead of rewriting for the cloud, you use a hosting company that puts your existing code on VM images that can be dynamically scaled as demand changes.

相比于为云重写代码，在虚拟化中你只需要将你现有的代码，放在可以根据需要动态扩展的虚拟机映像中即可。

这是一个非常强大的功能，因为它支持现有设计和代码的按需扩展(参见参考资料)。

At startup, the on demand configuration code inside the secure proxy reads the static route file and builds the in-memory routing data.

在启动后，安全代理内部的随需应变配置代码将读取静态路由文件并构建内存路由数据。
