Featureserver on AppEngine
AppEngine is awesome. The more we use it, the more we like it.
Recently, someone contacted us who needed a site up, in a hurry, to serve up some points on a google map. The catch was there were about 50k points (so it seemed server side clustering might be nice). Also they wanted to be able to serve up at _least_ tens of millions of requests a day. And maybe quite a lot more. Given the scaling requirements, it seemed like AppEngine might be a nice fit, since then we wouldn't have to worry so much about tons of caching, or ensuring clients made similar bounding box requests, and so forth. And as for the posting/getting of points to/from appengine, we decided to go for using FeatureServer as a base. If you're not familiar with featureserver, a quick overview: It makes it easy to (amongst other things) post/update your features to some datastore, and pull them out with bounding box and/or attribute queries in a variety of vector formats (kml, json, wfs, etc).
