Abstract: Method, system, and computer program product to enforce application dependencies, by building a data model based on inputs specifying relationships between a plurality of applications, generating, based on the data model, a list of candidate executions for a first application having a specified relationship with a second application, and outputting a visual representation of the data model, the visual representation comprising a plurality of objects representing the plurality of applications and arranged to represent the relationships between the applications, the list of candidate executions, and one or more user interface elements allowing user navigation between the first application and the second application, of the list of candidate executions.

Abstract: Fault tolerance is provided in a distributed system. The complexity of replicas and rollback requests are avoided; instead, a local failure in a component of a distributed system is tolerated. The local failure is tolerated by storing state related to a requested operation on the component, persisting that stored state in a data store, such as a relational database, asynchronously processing the operation request, and if a failure occurs, restarting the component using the stored state from the data store.
