The title was AppEngine Nitty Gritty: Scalability, Fault-Tolerance, and Integrating With Amazon EC2. We gave high-level advice about how to design an application for high loads and how to architect an application that makes use of multiple cloud computing environments. We also went straight to the dirty grime and shed light on some issues we encountered while building the Walk Score API – issues like unpredictable data store contention and the failure of basic sharding techniques for certain high-scale features.
