Bill Gibson is off and running on his blog. See his latest post that dives into SDM and add him to your favorite RSS aggregator, if you haven’t already.
The Whitehorse Distributed System Designers are based on SDM - the System Definition Model. SDM offers a simple model for representing computer systems that can help in many parts of the design, deployment and management space. I'll try over an occasional series of posts to introduce some of the key SDM concepts and how they play together. I'll also show how we can extend these to do some neat things in the application architecture modeling space.
