nges we face at Amazon.com, one of the largest e-commerce operations in th

e world; even the slightest outage has significant financial consequences

and impacts customer trust. The Amazon.com platform, which provides servic

es for many websites worldwide, is implemented on top of an infrastructure
of tens of thousands of servers and network components located in many dat

acenters around the world. At this scale, small and large components fail

continuously and the way persistent state is managed in the face of these f

ailures drices the reliability and scalability of the software systems. In

this talk, Swami Sivasubramanian will present the desgn and implementation
of Dynamo, a highly available key-value storage system that some of Amazo

n''s core services use to provide an "always-on" experience. He
will also compare and contrast the efforts in making a highly available re

lational database.
