APPLICATION COMPATIBILITY CHECKING IN A DISTRIBUTED COMPUTING ENVIRONMENT

In various embodiments, methods and systems for maintaining compatibility between applications, based on feature-set constraints are provided. A distributed computing system provides Platform as a service (PaaS) including a software framework in a service model of cloud computing. A known compatibility baseline is established for features of a first application and a second application. The known compatibility baseline inherently includes a baseline set of unenumerated features of the applications. It is determined that the first application is compatible with second application based on comparing an explicit enumeration of added features or removed features in a feature set of the applications. The added features or removed features are tracked after the baseline set of unenumerated features is defined. The determination whether the first application and the second application are compatible is communicated for processing the first application and/or the second application.
