Having done distributed systems for many years the only thing I would like to add is that all systems are not equal so some of the things mentioned in this article might not work. It was my experience that the real key to making a distributed system work was to identify the critical paths and segment and encapsulate the functionality of different components into the smallest possible implementations. Then define robust messaging between the components to allow for coordination. In my case we were making control systems for Naval systems so we had a much different set of requirements then websites, but it was a massively distributed system ( over 10K nodes ) with a strong requirement for redundancy and latency ( no ethernet here just field bus networks ). I even wrote and published a paper on it some time back. Point is this is not the only path there are other ways to implement distributed systems and there is still much to be discovered in the field.
