Inter-platform Interoperability for Zero Defects Platforms – API Gateway

Background: Zero Defects Manufacturing Platforms will be integrated with external Internet of-Things platforms of commercial manufacturers as well as other (research) projects. In doing so, the data sources available there should be usable as well as the integration of security measures to ensure controlled and frictionless cross-platform access for everybody. Objective: This paper describes an implementation approach of making use of open standards as an example of good design patterns and architecture and gives a short impression of the performance reachable by following these practices compared with other solutions.Method: Using a prototype implementation and conducting a systematic performance study.Results: A prototype implementation by making use of open standards (e.g. Swagger) and open-source tools (e.g. Spring framework) that have been evaluated.Conclusion: The results provide a reference to developers to design a system to enable controlled and smooth cross-platform access in manufacturing environment.
