Anybody interested in web performance & operations should read Todd Hoff’s High Scalability blog.
When it becomes clear you must grow your website or die, most people have no idea where to start. It’s not a skill you learn in school or pick up from a magazine article on a plane flight home. No, building scalable systems is a body of knowledge slowly built up over time from hard won experience and many failed battles. Hopefully this site will move you further and faster along the learning curve of success.
Some of my favorite posts include Scaling Twitter and Log Everything, All The Time.
Todd is doing a great job spreading knowledge and (hopefully) reducing common growing pains. Check out the site and please keep sharing your stories.
