11 Interactions – Join Instance

12 Interactions – Get Real-time Data

13Conclusions The architecture has been useful for implementing the components, even using OSGi Layers differentiation is still clear and it enables flexibility and evolution  Adopt several M2M frameworks From the BETaaS Instance perspective, we can use a mix of Star and P2P architecture  Distributed & Centralized approach – Simplify certain operations and improve network usage – Increase reliability and performance The architecture is valid for increasing the capabilities of the platform in the future
