http://highscalability.com/blog/2010/1/22/how-buddypoke-scales-on-facebook-using-google-app-engine.html Most of the cost of BuddyPoke is in content delivery. The main app for BuddyPoke is a flash file must be served. These costs are much higher than the costs for running the actual application. Dave is investigating Rackspace for file serving. GAE has a relatively high failure rate for accessing content, which is acceptable when returning avatars, but is not OK for loading up the initial image. ie. the failure rate for static file serving on App Engine is so high that BuddyPoke has to use an expensive content delivery network to serve it's flash app. :-( > also, if they're static files, the blobstore api would be much more > appropriate than the datastore. have you tried it? Is the blobstore API faster/more-reliable than serving from the db/ memcache? Obviously, if your files are > 1MB then the blobstore is your only option. If you have a few static files then static file serving is an option. But if you have dynamic files < 1MB there are now two options: db/memcache or blobstore. Which is better, and why? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group. To post to this group, send email to [email protected].
