The Lynx project as a compliance service-oriented platform that seeks to address compliance and regulatory related needs of its clients and users, comprises many services ranging from the fields of Information Extraction and Linking, Knowledge Management and Sematic Web; for which there is the need for a high level technical architecture design that integrates these services in order to address the objectives of the project. This document, therefore, provides a detailed description of the technical architectural design solution for the Lynx platform. Architecture design in any software development project as in the case of Lynx serves as a blueprint that drives the smooth design and implementation of the software system. Once implemented, fundamental structural choices are costly to change. In this deliverable, standard architectural patterns such as the Monolithic architecture pattern, SOA and MSA are described narrowing down on the choice of the architectural patterns that suites the architectural design needs of the Lynx platform with reference to the functional and technical requirements of the Lynx platform. For the Lynx platform, we adopted the MSA pattern which supports loose coupling between services; a feature that allows for easy separation of work and which makes this pattern most adaptable to the Lynx platform requirements. The document also provides detailed description of the logical and physical architectures. The logical architecture describes the following: Access control system Microservices coordination system Communication system Foundational microservices How the software microservices are wired together to form a larger software system The physical architecture describes the type of infrastructures, the platform and the deployment architecture of the software application and how to deliver the deployable system.
