You should not look at scalability as a bandaid or a one time fix.
As the usage of your application changes, your scalability requirements will change and evolve. Also, there is no silver bullet for addressing scalability. It is a mix of various approaches like caching, replication, distribution, performance tuning, hardware upgrades etc. You should choose from those based on the context of "what you want to scale" and where will you get maximum bang for the buck!

看看 Cal Henderson 的《构建可扩展的网站》，作者：O'Reilly
http://www .amazon.com/Building-Scalable-Web-Sites-Applications/dp/0596102356
他是 Flickr 背后的人。
另请查看 highscalability.com，他们拥有一些负载最多的网站的架构。

he's the guy behind Flickr.
Also have a look at highscalability.com, They have some of the architectures of the most loaded sites out there.
您不应该将可扩展性视为创可贴或一次性修复。
随着应用程序的使用情况发生变化，您的可扩展性需求也会发生变化和发展。此外，解决可扩展性问题也没有灵丹妙药。它是各种方法的组合，如缓存、复制、分发、性能调整、硬件升级等。您应该根据“您想要扩展的内容”的上下文来选择这些方法，以及在哪里可以获得最大的性价比！

其中有一些关于可扩展性以及如何不陷入“受追捧”的可扩展性口号的陷阱的好信息

which has some good information about scalability and how not to fall into traps of "sought after" scalability mantras
我对此进行了相当多的搜索。最终归结为这三本书。
高性能网站
更快的网站
I have done quite a bit of search on this.Finally boiled down to these three books.
High Performance Websites
Even faster websites
