Scaling big web sites

Peter Van Dijck's Guide to Ease blog contains a nice list of presentations from a few big Web 2.0 properties. Definitely an interesting read, especially given that I've worked with some of the largest of properties through my time at Citrix/NetScaler (e.g., Google, eBay, Amazon, MSN, etc.) and as a result have typically seen this discussion from the networking side. Most of the presentations listed take the view from the application developer side which is indeed a different beast.
