I recently attend a Philadelphia Area Linux Users Group (PLUG) meeting presented by Toby DiPasquale titled “Google Internals”
Slides here: Google Internals talk for PLUG by Toby DiPasquale.
Why is this of interest on a Linux blog? As many of you may already know, Google uses a version of Red Hat to power their servers, running on old kernels (it is speculated that they run on 2.0 or 2.2 kernels).
This Google Internals talk takes you through the basics of how Google uses their approximately 450,000 servers to run everything from Google search to GMail worldwide. The slides are based on information gathered from reliable Google sources, including talks given by Google staff, and gives you a very basic framework for understanding what is “under the hood” over at Google.
