This is guest post by Michael DeHaan (@laserllama), a software developer and architect, on Ansible, a simple deployment, model-driven configuration management, and command execution framework. I owe High Scalability a great deal of credit for the idea behind my latest software project. I was reading about how an older tool

As it is said in the recent article "Google: Taming the Long Latency Tail - When More Machines Equals Worse Results" , latency variability has greater impact in larger scale clusters where a typical request is composed of multiple distributed/parallel requests. The overall response time dramatically decreases if

The Peregrine falcon is a bird of prey, famous for its high speed diving attacks, feeding primarily on much slower Hadoops. Wait, sorry, it is Kevin Burton of Spinn3r's new Peregrine project--a new FAST modern map reduce framework optimized for iterative and pipelined map reduce jobs--that feeds on

LevelDB is an exciting new entrant into the pantheon of embedded databases, notable both for its pedigree, being authored by the makers of the now mythical Google MapReduce and BigTable products, and for its emphasis on efficient disk based random access using log-structured-merge (LSM) trees. The plan is to keep

I met the CodeFutures folks, makers of dbShards, at Gluecon. They occupy an interesting niche in the database space, somewhere between NoSQL, which jettisons everything SQL, and high end analytics platforms that completely rewrite the backend while keeping a SQL facade. High concept: I think of dbShards as a sort
