The Fog.Mark Hambleton

March 2018

Today’s world of devices connected to clouds looks set to evolve with more intelligence and processing being pushed to the edge or migrating between the cloud and the edge. The very definition of edge is evolving too. In this presentation we will look at some potential futures made possible by the emergence of the fog and its implications for the segments that it embraces.

Introduction

Today I’d like to

• Introduce you to a “new” trend

• Briefly describe the what and the why

• Describe some key attributes

• Explain why it’s important to us all

• And then hopefully you’ll be as excited as I am… ;-)


Why me?


The smartphone revolution


IoT - now


6

The next phase of IoT is driving big changes


Really? Smart home == autonomous vehicle?

When you think about a smart-anything - it will (most likely)

• Host multiple sensors of different types

• Control actuators of different types and

• Require some level of safety

• Connect to multiple cloud services for different purposes

• Require storage for local content caching

• Require compute resources to process data and make decisions

So in some respects: yes, really…


So, what’s the problem?

Examples…


Public Safety Video Surveillance

Problem• Cloud doesn’t scale for wide

surveillance • Rapid decisions on location

Challenges• Terabytes of data from high definition

cameras

Fog Technology• Intelligent partitioning of video

processing between cameras and cloud

• Real-time, latency sensitive analytics


Supply Chain Delivery Aerial Drones

Problem• Volume/expense of traditional delivery

Challenges• Safety, bandwidth, and operational

challenges

• Regulatory complexities

Fog Technology• Coordinates drone landings, take offs,

loading, unloading, maintenance

• Autonomous awareness, analysis and sub-millisecond response to changing conditions

• Security

• Highly scalable


Process ManufacturingCraft Brewing

Challenge• Maintain quality and consistency working with

natural ingredients

• Keep the brewing recipe a secret

• Reduce variances that can be introduced by manufacturing equipment / machinery, processes and weather.

• Predictive maintenance

• Optimize factory investments when faced with demand fluctuations

Why Fog

• Creation of a digital twin frees the brewer to explore new recipes.

• Privacy of secret recipe(s)

• Fog-enabled predictive maintenance for proactive detection/repair.

• Fog-based resource sharing


Edge Intelligence, enabling enterprises, manufacturers, infrastructure, cities and IoT vendors with real-time business and operational insights

• Reduces, analyzes, trains & predicts from edge data, on-the-fly

• Creates intelligent Digital Twin models of reality from gray data

• Edge compute fabric for analysis & ML driven predictions

• Delivers business insights by real-time UI/API

So what?

Services closer to the edge• Distributed compute

• Varying types / capacities• Multiple architectures

• Storage• Valuable data at the edge• Content protection

• Interoperability• Standards based

• Security• Trust• Privacy• Updatability and up to date!


And it opens up so many new opportunities…
