Scaling architecture and web sites is really something I find exciting. I’ve playing with scaling various software for many years, but it is just recent years I’ve come to use this in production (primarily through YippieMove).
If you’re curious about scaling your website, I can really recommend the following video lecture from Harvard. It goes though concept that you might have run across in various blog-posts before. It is not super-technical, so even if you’re new to programming etc., you should still be able to understand the entire lecture.
