About the Industrial Internet


Here are my “Cliffnotes” about Predix, GE’s brand name for their #IndustrialInternet.

I want you to feel confident that you’ve mastered this skill. That’s why this takes a hands-on approach where you type in commands and we explain the responses and possible troubleshooting. This is a “deep dive” because all details are presented.

Like a good music DJ, I’ve carefully arranged the presentation of concepts into a sequence for easy learning, so you don’t have to spend as much time as me making sense of the flood of material around this subject.

Sentences that begin with PROTIP are a high point of this website to point out wisdom and advice from experience. NOTE point out observations that many miss. Search for them if you only want “TL;DR” (Too Long Didn’t Read) highlights.

Stuck? Contact me and I or one of my friends will help you.

Videos introduced by real workers

You won’t be taught how to actually DO anything in YouTube videos under the “Predix Developers” section within GE Digital YouTube account.

But the videos are a good overview by people who actuallyy work there.

In this video: A Developer’s Take on Predix , Matt Momont (@muymoo), front-end UI software engineer, says:

“The apps can be built by one person. Everything is stood up for you and managed for you.”

What is “everything”?

Industrial Security and Scalability

A lot if you’re talking about large enterprises and their security and scalability concerns. These issues are what “industrial” systems provide versus “consumer” oriented systems.

As an example of the velocity of data storage within an industrial system, jet engines (built by GE) on a plane creates 50 TB (terrabytes or 1,024 Gigabytes) of data during each day of flying.


Denzil Samuels, GE Digital’s Global Head of Alliances, Channels, Business Development & Ventures at ge.com/digital/partners in this video: Predix: The Opportunity for Partners [0:26] the industrial cloud is “a bigger opportunity than the enterprise and consumer cloud. And yet there is no one there.” VSI can build a business. Service providers working on connected devices talking to each other. ISVs write code that run without worrying about hardware, storage. Cisco can sell compute power.

TODO: List Predix partners

GE’s competition

GE is in competition with other large “unicorn” technology giants.

Microsoft’s CEO Satya Nadella in their 2016 partner conference mentions the leading-edge technologies to be:

“Chatbots, machine learning, augmented reality, and cloud-based automation”

This photo from Microsoft shows a 3D shaded Hololens image of a jet engine next to someone wearing a Microsoft Hololens headset.

SAP uses adapters for MQTT (MQ Telemetry Transport), a publish/subscribe, extremely simple and lightweight messaging protocol, designed for constrained devices and low-bandwidth, high-latency or unreliable networks.

Salesforce, IBM, and most others all mention their push to machine learning in 2016.

Big use cases

A lot of the use cases and examples for Predix refer to giant wind turbines, giant aircraft engines, etc. because that’s where GE has the experience and the data (time-series data).

PROTIP: GE was a major part of the first industrial revolution. It can be said that GE is the company that literally invented the light bulb because it was formed mostly by Thomas Edison, who did invent the light bulb, the phonograph, and a bunch of other necessities. (I visited his workshop in Michigan where it now lives as a museum showing the various stages of inventions from early protoypes)

PROTIP: GE’s size makes it uniquely able to serve other large industrial organizations.

GE’s industry-specific divisions include: Energy, Healthcare, Transportation

Marketing materials specifically mention these industrial customers:

  • Pitney Bowes
  • RasGas
  • E.ON
  • Exelon
  • City of San Diego
  • Toshiba
  • Lixil

QUESTION: Example of start-ups or even consumers using Predix?

This 2-minute video: GE’s Asset Performance Management Powered by Predix is a cartoon that asks “what if” and outlines the process:

[0:32] 1) Get connected. Capture data to get a more complete and accurate view of machine and equipment health.

[0:45] 2) Reliability management. Use andvanced analytices to get insights, predict and diagnose issues early, and respond before failure. These insights help you make better decisions.

[1:00] 3) Get optimized. Create maintenance strategies that balance reliability, performance, and cost. Maintenance Optimization.

[1:42] The complex business challenges:

  • Rising costs
  • Safe operation
  • Performance & reliability
  • Security concerns
  • Workforce turnover

PROTIP: In the new industrial age, the focus is on proactive and predictive. It’s not enough for metrics to just measure the “productivity” of assets such as machines.

PROTIP: In the advanced IoT world, the role of people is no longer to run around collecting data and filling out forms. People are relatively more expensive than machines. So sensors (in stationary sensors and cameras, robots, and drones) gather the data.

PROTIP: How do humans supervise massive data streams? This is when software can (and need to) do much of the planning and scheduling to available capacity.

### Buzzwords #

Several business and technical buzzwords are uttered in various marketing materials without much explanation:

QUESTION: What do these mean? Explain:

  • Connected assets

  • Industrial data science

  • Industrial data management

  • Asset lifecycle

  • Operations & Intelligence

  • Monitoring & diagnostics

  • Risk mitigation

Architecture video

In this video: Predix Architecture, Steve Winkler, Principal Architect, Predix Platform Leadership, says Predix Machine is the stack installed locally on gateways and controllers providing edge analytics, even when normal connectivity is not available.

The text of the vide is in this Predix Architecture white paper from September 2015.

Archicture diagram

This diagram illustratrate the major components within the “ecosystem” Predix operates:

Technical buzzwords spoken in this video include:

  • “Ops” is an abbreviation for “Operations”.


Questions in the $350 Predix Certified Developer on-line exam are grouped by the boxes above:

  • Edge software and services containing Predix Machine agents and sensors, on the left side
  • Assets

  • Analytics
  • Data Services
  • Data Management
  • Security
  • DevOps

  • App UI Services
  • Predix Cloud

Each of these is a category of cloud services listed at
which also include:

  • Geospacial services
  • Intelligent Enviornments

PROTIP: I evaluate each service in the above categories at my Predix services page.

### User Security #

[6:00] into the video: PROTIP: The principal way GE and most others invented during the first industrial revoluton to handle complexity under scale was to separate workers into various departments of people to reduce the overhead of groups continuously communicating with each other. During the first industrial revolution, communication through telegraph and telegrams was expensive and thus needed to be funneled and controlled. This strategy is reflected in the security for software systems.

Each part of the organization would handle just one aspect (one space) of the whole. Consequently, software for one space typically do not consider the needs of another space since the whole point of segregation is so departments don’t have the overhead of communicating with each other.

PROTIP: The public internet is challenging the traditional segmentation mindset. Advanced systems of today transcend organizational boundaries. Workers who grew up with Twitter are used to having each person able to communicate with all others. Those who grew up with Facebook are used to being in on conversations of their friends, no matter how far away.


Predix adopts the microservices architecture popular today, which consists of many “loosely coupled” microservices, each focused on a single task. Microservices operating mostly independently, so they are easier to build, maintain, and scale.

Predix fundamentals

This 51 minute video summarizes what Predix offers.

From machine to mobile, a cloud-based developer platform for creating innovative, highly scalable, industrial internet applications that turn real-time operational data into actionble insights.

Click on each link in the paragraph above to go directly to more about each aspect.

This last phrase, “actionable insights” is the revolution. It’s what different, and worth a lot of money.

Actionable insights

PROTIP: Most existing systems that produce a bunch of graphs with lines crossing each other expect human experts to interpret what the various lines mean and what to do about them.

In today’s world, a company can be running hundreds of computers, each providing dozens of “metrics” about itself. The introduction of robots and drones and all sorts of things monitoring everything, it’s too much to digest by any one person.

PROTIP: The “artificial intelligence” that Predix offers can interpret the various lines simultaneously and recommend specific actions, or even invoke commands for people to take care of what it thinks needs to be done. But hopefully not quite to the sophistication (and terror) of computer systems portrayed in the fictional “Personal of Interest” TV series.

In July 2016, GE announced that Predix will also run in the Microsoft Azure cloud.

PROTIP: Access to the Microsoft Azure cloud links Predix to Microsoft’s Cortana Artificial Intelligence capabilities.

Cloud Platform

### Starter Packs #

[1:07] Services Catalog page

[2:27] The “cf bind-service [app-name] my-service-instance” is a command invoking the cf (cloud foundry) cli (command line) tool.

[3:32] The application with the turbine picture has a URL of “https://rmd-ref-app.run.aws-usw02-pr.ice.predix.io” running in a temporary instance within the “aws-usw02” (Amazon Web Service us-west-2) cloud envionment is the “Reference App” defined as an example (baseline) for how a completd app looks and works. It includes data for monitoring and diagnostics of things running remotely from an office. Thus the abbreviation RMD, which stands for Remote Monitoring and Diagnostics.

UX/UI Visual Design system

As you might expect from a large corporation, someone at GE corporate would invent rules around design of navigation, form layout, toggles, sliders, etc. for everyone else in the company.

The “design system” is a grand name that encompasses the Visual Language + Interaction Patterns + Technology Framework for personas.

GE’s Software Design Hub website provides a reference implementation, stencils, and copyrighted GE Inspira font Bold, Italic, Bold Italic, Sans Regular, Small Caps Regular, and GE Inspira Serif?.

Download each by clicking on each link above. BTW, I also like GE Iron Works Regular.

Cloud Foundry

Pivotal Cloud Foundry (PCF)

1:29 VIDEO: Inside the Predix Cloud is a bunch of photos of a data center set to music.

Per Wikipedia, Pivotal Software was formed in 2012 after spinning out of EMC Corporation. On April 24, 2013, the organization announced both a $105 million investment from General Electric and its PaaS offering, Pivotal Cloud Foundry (PCF), a cloud-enabled application platform for private cloud initiatives and public cloud providers.

PWS (Pivotal Web Services) provides $87 of initial fees and 2GB free. Whoopee! After that, it’s $0.03/GB hour.

PWS runs on PCF (Pivotal Cloud Foundry).
