A communications mapping system to generate a relational communications graph for a source application is provided. The deployment system includes at least one processor and a memory. The at least one processor configured to receive one or more source elements associated with the source application, the source application including a first sub-application and a second sub-application. The processor is also configured to identify a dependency relationship between the first sub-application and the second sub-application based at least in part on an inspection of the one or more source elements. The processor is further configured to generate the relational communications graph including the first sub-application, the second sub-application, and the dependency relationship and provide the relational communications graph for use in executing the source application in an execution environment.
