I recently came across this article at Infoworld titled How to Make PHP Apps Scale. The article is a bit short on details, particularly in terms of solutions, but I think does a decent job of explaining where the bottleneck commonly is on PHP-MySQL-Apache sites.

phpmaster recently posted an article titled Introduction to MongoDB. I’m not entirely sold on non-relational databases yet, in that while I can see how wonderfully beneficial they can be in many situations, they’re not as ubiquitously useful as all the hype would seem to suggest. But in any case, a good article like this one, which introduces MongoDB, shows how to install support for it in PHP (although the instructions are for Unix-like systems), and provides code for actually interacting with a MongoDB database is worth the time to read.
InfoWorld just posted a good and long article discussing the particular strengths and weaknesses of various NoSQL (aka, non-relational) databases. If you’re intrigued about what NoSQL databases are all about, and maybe even thinking about starting to play around with one, it’s well worth your time to read.
