SOSP 2007 paper discussing Dynamo (pdf version; the html version is in the blog entry above)
Alex Iskold, Amazon Dynamo: The Next Generation Of Virtual Distributed Storage, readwrite.com blog, October 30, 2007.
A posting that digests the Dynamo paper. A good place to start since this is shorter and easier to understand than the Dynamo paper. However, it does not really describe the Dynamo architecture or how it really works, so you should still read the paper.
Consistency and availability in Amazon's Dynamo

Buzzwords:
zero-hop DLT, decentralized, symmetric, incremental scalability, heterogeneous, optimistic replication, "always writable", consistent hashing, virtual node, balanced load distribution, vector clocks, metadata hints, Amazon S3.
