Update: Short presentation NYC by Bryan Fink demonstrating the riak web-shaped data storage engine Riak is another new and interesting key-value store entrant. Some of the features it offers are: * Document-oriented * Scalable, decentralized key-value store * Standard get, put, and delete operations. * Distributed, fault-tolerant storage solution. * Configurable levels of consistency, availability,
Scale-Out is incrementally adding servers as needed to scale rather than buying larger servers. Here's the MySQL idea of what a scale-out architecture looks like: This MySQL article lists 5 problems to avoid when scaling out: 1. Don't Think Synchronously. Introduce asynchronous communication, parallelization, and strategies
There are many reasons to roll your own data storage solution on top of existing technologies. We've seen stories on HighScalability about custom databases for very large sets of individual data(like Twitter) and large amounts of binary data (like Facebook pictures). However, I recently ran into a

Space-based architectures are an alternative to the traditional n-tier model for enterprise applications. Instead of a vertical tier partitioning, space based applications are partitioned horizontally into self-sufficient units. This leads to almost linear scalability of stateful, high-performance applications. This is a recording of a talk I did last month where

Recently I attended a lecture presented by Manik Surtani , JBoss Cache & Infinispan project lead. The goal of the talk was to provide a technical overview of both products and outline Infinispan's road-map. Infinispan is the successor to the open-source JBoss Cache. JBoss Cache was originally targeted at
