Though Google is loath to open source the foundations of its massive online infrastructure, it does share code for tools at the edge of its network, tools designed to accelerate the actual delivery of web stuff. Mountain View doesn't want Facebook rebuilding the Googlenet. But it is intent on accelerating the web as a whole. Ultimately, this juices the Google bottom line.
In June 2009, Google unveiled SDPY, an application layer protocol designed to improve the speed of the existing HTTP protocol, and last fall, it open sourced something it rather inelegantly calls mod_pagespeed, an Apache web server module that accelerates page delivery by optimizing content as it is served. It's yet to been seen how widely either will be used, but both are making at least some headway outside the Googleplex.
SPDY has turned up inside multiple operations – including a website acceleration service known as Strangeloop and the Israel-based content delivery network Cotendo – and mod_pagespeed is finding its own way as well.
