原文:
* *Each piece of the stack must be easily moved or replicated* . If Apache for some reason doesnt work for a given deployment, you should be able to swap it out for another server with a minimum of fuss. Or, on a hardware level, if a Web server fails, you should be able to replace it with another physical box with minimum downtime. Remember, this whole philosophy is based around deployment on cheap, commodity hardware. Failure of individual machines is to be expected.
翻译:
* *Web栈中的每个部分都必须易于移动或复制* 。如果在部署时因为某种原因Apache不能工作,必须能够在最小的代价下切换到其它服务器。或者,在硬件层次,如果Web服务器崩溃,必须能够在最小的宕机时间内替换到另一台机器。请记住,整个哲学基于将应用部署在廉价的、商品化的硬件上。因此,本就应当预见到单个机器的失效。
