Importance of Architectures

Sanjay SarmaDean of Digital Learning, Professor of Mechanical Engineering



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

HOURGLASS ARCHITECTUREHOW THE INTERNET WAS TAMED

Copper, radio, fiber optics, other

Sonet, CSMA, …

Ethernet, PPP

IP

TCP, UDP

HTTP, SMTP, …

WWW, Email, telephony, video



COBWEB OF THINGS

Implemented in layers

Several protocols

Different bridges, controllers patching system

Security?

Maintainability?

Rules baked in instead of changeable

Bridge

Controller

Device

BlueTooth

Zigbee

Insteon

Internet

Rules baked in



CLOUDY WITH A CHANCE FOR THINGS

Lift everything

to the cloud

Local fog

Controller

For real time

Implement

rules here

Communications

across facilities

Implement

rules here



CLOUD THINGS

Different devices with different protocols

Zigbee, Blue Tooth, 6 Low Pan, etc

Bridges, routers, Cotrollers

Cloud

Things

Services

New semantics

Home automation, factory automation , etc.

Real time control

Insert

rules here

Firewall



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
