Stories about: SDL

Most cloud applications have development (or at least scripting) capabilities that allow for deep customization plus some level of database access and computational capabilities. But even the best of the cloud applications must put in limiters for their platform/development environments: an app isn't a general purpose run-time or generic object container. For example, the development language must be made safe for a multi-tenant deployment, and must be well-behaved so that user code can't take down the virtual machine, database, or overall application. Further, some kinds of language constructs must be limited to prevent resource hogging and deadlocks. (Indeed, if you think about the billion lines of user code that Salesforce.com has running in their cloud, keeping quick responsiveness and good uptime stats is a non-trivial task.)
