Abstract
An important trend in information technology is the use of
increasingly large distributed systems to deploy increasingly complex
and mission-critical applications. In order for these systems to
achieve the ultimate goal of having similar ease-of-use properties as
centralized systems they must allow fast, reliable, and lightweight
management and synchronization of their configuration state. This
goal poses numerous technical challenges in a truly
Internet-scale system, including varying degrees of network
connectivity, inevitable machine failures, and the need to distribute
information globally in a fast and reliable fashion.
In this paper we discuss the design and implementation of a
configuration management system for the Akamai Network.
It allows reliable yet highly asynchronous delivery of
configuration information, is significantly fault-tolerant, and can
scale if necessary to hundreds of thousands of servers.
The system is fully functional today providing configuration
management to over 15,000 servers deployed in 1200+ different networks
in 60+ countries.
