Experience with some principles for building an internet-scale reliable system
Mike Afergan, Joel M. Wein, Amy LaMeyer · 2005
We discuss the design methodology used to achieve commercial-quality reliability in the Akamai content de-livery network. The network consists of 15,000+ servers in 1,100+ networks and spans 65+ countries. Despite the scale of the Akamai CDN and the unpredictable nature of the underlying Internet, we seek to build a system of extremely high reliability. We present some simple prin-ciples we use to assure high reliability, and illustrate their application. As there is some similarity-in-spirit between our implementation and recent trends in the research lit-erature, we hope that sharing our experiences will be of value to a broad community. 1
