We already have enough information to justify the commandments of cloud programming: 
AppEngine has flowless switching for high robustness.
We can't store data other than in the cloud, because in a sequence of requests, we might get a different server instance and different application instance for a second request!
We need strong consistency in the cloud, because otherwise, server instances and application instances will see different versions of data.
