Werner Vogels:

Today is a very exciting day as we release Amazon DynamoDB, a fast, highly reliable and cost-effective NoSQL database service designed for internet scale applications. DynamoDB is the result of 15 years of learning in the areas of large scale non-relational databases and cloud services.

No words can describe (yet) the magnitude of this announcement.

From the series “if you didn’t read the paper, here’s an overview”, this time Dynamo: Amazon’s Highly Available Key-value Store:

The Dynamo paper can be difficult to read. The main issue we had is that the authors don’t always motivate the different components of the system. For example, consistent hashing is one of the earlier concepts introduced in the paper, but it is difficult to see why it is used and how it contributes to increased availability until later on. It is best to approach each section of the article as a self-contained idea, and wait until the end to see how they are combined. It took us two sessions to get through the paper, so don’t be surprised if you find it slow going.

Worth checking even if you read the paper.
