内容简介

Slow websites infuriate users. Lots of people can visit your web site or use your web application - but you have to be prepared for those visitors, or they won't come back. Your sites need to be built to withstand the problems success creates. "Building Scalable Web Sites" looks at a variety of techniques for creating sites which can keep users cheerful even when there are thousands or millions of them. Flickr.com developer, Cal Henderson, explains how to build sites so that large numbers of visitors can enjoy them. Henderson examines techniques that go beyond sheer speed, exploring how to coordinate developers, support international users, and integrate with other services from email to SOAP to RSS to the APIs exposed by many Ajax-based web applications. This book uncovers the secrets that you need to know for back-end scaling, architecture and failover so your websites can handle countless requests. You'll learn how to take the "poor man's web technologies" - Linux, Apache, MySQL and PHP or other scripting languages - and scale them to compete with established "store bought" enterprise web technologies. Toward the end of the book, you'll discover techniques for keeping web applications running with event monitoring and long-term statistical tracking for capacity planning. If you're about to build your first dynamic website, then "Building Scalable Web Sites" isn't for you. But if you're an advanced developer who's ready to realize the cost and performance benefits of a comprehensive approach to scalable applications, then let your fingers do the walking through this convenient guide.

Web应用则是由具备分离交付机制的数据组成的。系统架构师的任务是通过仔细进行初期设计和谨慎的改进设计，来最小化每个组件重构所需时间，这样就很好了。在开始设计应用程序时，要避免采取任何可能导致我们陷入死角的步骤。要确保每一个决定都是快速可逆的，这样在迭代过程发现犯了错误也不用担心——对于新的特性，技术上可以先在非常基本的水平进行设计，实现它，然后快速迭代
