We are extremely fortunate that the paper was selected for publication in SOSP only a very few true production systems have made it into the conference and as such it is a recognition of the quality of the work that went into building a real incrementally scalable storage system in which the most important properties can be appropriately configured.ĭynamo is representative of a lot of the work that we are doing at Amazon we continuously develop cutting edge technologies using recent research, and in many cases do the research ourselves. As far as I know Dynamo is the first production system to use the synthesis of all these techniques, and there are quite a few lessons learned from doing so. We submitted the technology for publication in SOSP because many of the techniques used in Dynamo originate in the operating systems and distributed systems research of the past years DHTs, consistent hashing, versioning, vector clocks, quorum, anti-entropy based recovery, etc. Let me emphasize the internal technology part before it gets misunderstood: Dynamo is not directly exposed externally as a web service however, Dynamo and similar Amazon technologies are used to power parts of our Amazon Web Services, such as S3. The technology is designed to give its users the ability to trade-off cost, consistency, durability and performance, while maintaining high-availability. Dynamo is internal technology developed at Amazon to address the need for an incrementally scalable, highly-available key-value storage system. In two weeks we’ll present a paper on the Dynamo technology at SOSP, the prestigious biannual Operating Systems conference.
