Web Operations

这不本教你照图施工的运维手册，而是一场资深从业者之间的经验对话。全书以多人文集的形式，把 Yahoo、Flickr 等大规模网站的真实运作摊开给你看：有成功也有失败，有被验证的工具，也有需要自己判断的灰色地带。它反复强调一个观点——运维能力无法从课堂习得，只能在一次次'做出错误判断'中积累。书中对云与自建服务器如何混用、监控究竟该关注哪些指标、持续部署为何'小批量'更有效，都给出了带着个人立场的实操思考。适合那些不满足于'照做'、想理解运维背后'道'的读者；若只想要现成答案，这里未必满足。

John Allspaw is currently Operations Engineering Manager at Flickr, the popular photo site. He has had extensive experience working with growing web sites since 1999. These include online news magazines (Salon.com, InfoWorld.com, Macworld.com) and social networking sites that experienced extreme growth (Friendster and Flickr). During his time at Friendster, traffic increased 5X. He was responsible for their transition from a couple dozen servers in a failing data center to over 400 machines across two data centers, and the complete redesign of the backing infrastructure. When he joined Flickr, they had 10 servers in a tiny data center in Vancouver; they are now located in multiple data centers across the US. Prior to his web experience, Allspaw worked in modeling and simulation as a mechanical engineer doing car crash simulations for the NHTSA. Jesse Robbins is passionate about infrastructure, emergency management, and technology that helps people be safe, happy, and free. He serves as co-chair of the Velocity Performance & Operations Conference and is part of the O'Reilly Radar. Jesse currently advises companies in Seattle and San Francisco. He previously worked at Amazon.com where his title was "Master of Disaster" and where he was responsible for Website Availability. Jesse is a volunteer Firefighter/EMT & Emergency Manager, and led a task force deployed in Operation Hurricane Katrina.
