Intro to building scalable public web services (ref)

I have experience building small, internal web applications.

I'm looking for a good beginners introduction to the subjects of

1. Scalable web architectures (ex. what are the basic pieces?)


2. Managing public-facing web systems (ex. statistics, monitoring, alerting)

Most of the material I can find assumes knowledge of either (1) or (2) - I know neither.

Edit: Looking for an introduction to the underlying concepts and principles as opposed to "use [company]'s [product] for [problem]"
