The Internet of Things: Roadmap to a Connected World
Industries take off when there is a simple dominant architecture. Sometimes counterintuitive architecture.
Alternating Current
Packet switched networks
Cellular telephony
The World Wide Web

CONSIDER POWER GRIDS
AC was not intuitive but:
It enables step-up and and step-down transformation
So long-distance transmission
And rotating machinery

Offer a simple design metaphor
Standardized interfaces for reuse and reconfiguration
A level of abstraction and modularity
Prevent cascading failure
Enable repair and maintenance
Are often hourglass
Simpler to secure
Good architectures are often counterintuitive
GOOD ARCHITECTURES

Implemented in layers
Several protocols
Different bridges, controllers patching system

Maintainability?

The Internet of Things: Roadmap to a Connected World
CONCLUSION: ARCHITECTURES
If we plan to connect $50 billion things to the Internet
We better be very organized
The anthropomorphic framework is a good organizational principle(sort of like object-oriented programming)
Otherwise we will spend much time undoing what we have done, and suffering security breaches
