40. What’s a message?
Data on the move
•
•
•
•
Data: Sensors measurements, ...
Headers: Context, time sent, origin, destination, conversation, ...
Format: Xml, json, binary, ....
In transit: Traveling from origin to known (or unknown) destination, transient ...

45. Event stream
processing

46. Reactive Extensions
Determine what is interesting
•

Linq to events
Linq: Standing queries, always running
IObservable: Event streams, data flow through as it happens ...
Windowing: Provides time-based context

51. Takeaways
Proposal
• Evolution of the internet of things
• The stars may align to make hype reality
• Challenges
• Connectivity (Power consumption VS security)
• Addressing (IPV6)
• Data Volume
• Physical Boundaries & propriatary implementations
• Solution: Federated Bus
• Different transport
• Different protocol
• Same patterns (Command, Event, Query)
• Multiple levels (Device, Local Network, Cloud)
• Gateway takes care of translation, filtering & security
• MH: Message/Event processing as a service
• Standing Query: Rx
• Action
