Scaling Server Setup for Sharp Traffic Growth?

Ronin asks: "We are a young startup developing a yet another collaborative platform for academic users. Our platform (a) requires users to log-on to the website for extended period of time, and (b) is content intensive - stuff like courses, quizzes and assignments gets posted regularly. We're using a LAMP setup on a 1 GB P4 server. Our user base is small (about 1,200 users, 5-7% connected at any given time) but we expect it to grow rapidly. We expect sharp traffic growth, and are working to scale our server software & hardware setup linearly. What kind of server setup plan should we go for keeping in mind our content heavy application and that we may have to scale up rapidly. Can anyone share his/her experience with LAMP in dealing with scalability of high-traffic sites? Taking clues from the Wikimedia servers, we understand that the final configuration involves proxy caching for content, database masters/slave servers and NFS servers. We of course don't have such a high traffic, but it will be interesting to note what kind of server config you'd go for."

Traffic concerns?
