Servitization is one of the most significant trends that reshapes the information world and society in recent years. The requirement of collecting, storing, processing, and sharing of the Big Data has led to massive software resources being developed and made accessible as web-based services to facilitate such process. These services that handle the Big Data come from various domains and heterogeneous networks, and converge into a huge complicated service network (or ecosystem), called the Big Service. The key issue facing the big data and big service ecosystem is how to optimally configure and operate the related service resources to serve the specific requirements of possible applications, i.e., how to reuse the existing service resources effectively and efficiently to develop the new applications or software services, to meet the massive individualized requirements of end-users. Based on analyzing the big service ecosystem, we present in this paper a new paradigm for software service engineering, RE2SEP (Requirement-Engineering Two-Phase of Service Engineering Paradigm), which includes three components: serviceoriented requirement engineering, domain-oriented service engineering, and

This paper aims at improving the re-implementation of existing information systems when they are called to be involved in a system of systems, i.e. a federation of enterprise information systems that interoperate. The idea is reusing the local experiences coming from the previous development of the existing information system with the process of Model Discovery. To avoid re-developing the entire system when the enterprise needs to cooperate with others, this approach proposes to create local interfaces to code and decode information. The interfaces are instantiated by using models discovered. The interfaces are developed in accordance with the HLA standard that proposes message interoperability and synchronisation mechanisms among distributed systems. First, the authors recall the strong points of MDA/ADM methodologies for model transformation from conceptual level to implementation. Besides that they also recall the HLA standard. From this, a MDA&HLA framework is proposed to implement distributed enterprise components from the conceptual level of the federated enterprise interoperability approach. In addition, the authors add a model reversal methodology to the framework to guide re-implementation of legacy information systems, when called to achieve interoperability with other systems. To extend the scope of the approach, implemented web services are combined with HLA in order to facilitate the use of HLA in large distributed execution. The paper ends with an implementation example for validating the approach.
