Python Deployment Anti-Patterns
Deploying web applications is hard. No shiny continuous deployment talk and no DevOps coolness can change that. Or to use DevOps Borat’s words: “Is all fun and game until you are need of put it in production.“ There are some mistakes I see people doing again and again so I’d like to address them here.

Why Tarsnap doesn't use Glacier
On the surface, Tarsnap sounds like the perfect use case for Glacier. Out of every TB of data stored on Tarsnap, in any given month approximately 100 GB of data will be deleted, while only 33 GB of data will be downloaded; in other words, Tarsnap is very much a "write once, read maybe " storage system.

Why Tarsnap won't use DynamoDB
As I've blogged about before, the Tarsnap server code synthesizes a log-structured filesystem on top of Amazon S3 . As a result of this design, for each block of data stored on Tarsnap, the server code needs to keep track of two key-value pairs: First, to map a 64-bit machine number and a 256-bit block ID to a 64-bit…

A Tour of Amazon's DynamoDB
Amazon’s recent release of DynamoDB, a database whose name is inspired by Dynamo, the key-value database the distributed datastore they’ve been running in production for a good five to six years now.
