Relating two automata-based models of orchestration and choreography

摘要

We investigate the relations between two automata-based models for describing and studying distributed services, called contract automata and communicating machines. In the first model, distributed services are abstracted away as automata - oblivious of their partners - that coordinate with each other through an orchestrator. The second one is concerned with the interactions occurring between distributed services, that are represented by channel-based asynchronous communications; then services are coordinated through choreography.
