A necessary paradigm change to enable composable cloud-based M&S services

Cloud-based M&S can have many forms, from hardware as a service or cloud-based data for M&S applications to providing M&S as a service. In order to be able to compose such cloud-based M&S services, these services not only need to be able to exchange data and use such exchanged data, they also must represent truth consistently. Current paradigms are not sufficient to support these requirements. In this paper, a new paradigm is proposed that uses mobile propertied concepts to support consistent simulations using composable cloud-based M&S services. Mobile Propertied Agents (MPA) will utilize a floating middleware to establish an event-cloud orchestrated by a truth control layer. The result is a flexible Event Service Bus that ensure the consistent representation of truth in all systems connected to the event cloud, thus ensuring interoperability and composability by design in this cloud-based M&S environment.
