11. Interactions – Join Instance

12. Interactions – Get Real-time Data

13. Conclusions • 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 • Simplifycertainoperations and improvenetworkusage • Increasereliability and performance • The architecture is valid for increasing the capabilities of the platform in the future
