1.1.1 Certificate and Quiz’s- offline replays of the audio/video presentations
Lots of questions about what the requirements for certificate, attendance and what needs to be
completed, to receive a certificate. When will the certificates be sent, etc.
Will each day’s Quiz be available at an alternate time?
Several requests for the material to be made available for download/offline viewing and folks
that want to replay the content while not connected to Networks for Streaming. Ie Traveling, etc
2 LAPTOP/DESKTOP RECOMMENDATIONS
Students are strongly advised to have all the steps in the guide done PRIOR to attending a
workshop. Some of these steps take a long time and students who come unprepared will quickly
fall behind the others and not get as much value.
2.1 HARDWARE RECOMMENDATION FOR LABS
Any laptop/desktop capable of running Windows 10 should be adequate for any workshops.
Naturally, a bigger process, more RAM and disk space will be helpful. Students also benefit from
having access to a second monitor.
While not definitive, the following laptop as a minimal configuration works for learning cloud
and IoT:
• 8 GB RAM
• 120GB HDD
• USB Port(s)
• Second monitor is very useful when coding
2.1.1 “I cannot install Windows 10 to my laptop at this time.”
Ok, here are a few options you might consider.
2.1.1.1 External USB, Dual-Boot
Consider using an external, fast, solid-state disk drive. Install Windows 10 to that drive and then
dual-boot your laptop.
2.1.1.2 Virtual Host Software
You might consider using a virtualization product that supports passthrough USB (used by
Arduino) or consider installing Arduino on the host, which supports MAC and Linux OS and
Windows in the guest OS and just using the NOOB SD Card.

4 FAQ
This is a compilation of the most frequently asked Questions with respect to the Presentations
and Lab guide materials.
4.1 MOST FREQUENTLY ASK QUESTIONS
Q- My Huzzah device didn't get detected at USB COM# port... (if Arduino 1.85 is installed prior
to connecting Huzzah to the computers USB port, the driver for the Silicon Labs CP210x USB to
UART Bridge is included) or optionally update using the following driver
A-https://www.silabs.com/documents/public/software/CP210x_Windows_Drivers.zip
Q- Huzzah feather esp8266 if we unplug it, don't we need to re-upload to it again?
A- No. The last written code sketch stays in NV EEPROM memory on the ESP8266, until
overwritten there is a reset button that restarts the code (just above the USB power port) when
verifying /compiling with Arduino 1.8.5, files are written to dynamic memory space on the
ESP8266
Q- Do I need to reset the Huzzah between the labs? That's because I seem to get "Error opening
serial port 'COMx'. (Port busy). How do I reset it?
A-No. There is a small reset button near the micro USB power port. This essentially starts a
reboot of the running code. To overwrite the NV memory, a new Sketch must be compiled and
written to the Huzzah. There is a chance that you have either a second copy of Arduino 1.8.5
running, or the serial monitor is running. Only one application can write to or read from the
device at a given time.
Optionally – you can clear the contents of the EEPROM with this script
https://www.arduino.cc/en/Tutorial/EEPROMClear
Q-Huzzah is not showing up in Device manager – no(new)COMx port is discovered when
plugged into laptop.
A- Try an alternate USB port or cable and make sure you are using a proper USB cable, and not
a simple USB charging cable (with power leads only). You can also try to reinstall “C:\Program
Files (x86)\Arduino\drivers\dpinst-amd64.exe” or “C:\Program Files (x86)\Arduino\drivers\dpinst-
x86.exe, which will reinstall the driver.
Q-Can you turn off the huzzah or is pulling the plug the only option?
A-There is no logical shutdown or power off, simply remove the power source
5 | P a g e
© 2017 Microsoft
Q- Is there a technical reference document for the Huzzah Feather esp8266
A- https://cdn-learn.adafruit.com/downloads/pdf/adafruit-feather-huzzah-esp8266.pdf
Q- If the DHT22 sensor was not shipped in your kit, you may have the AM2302 wired sensor.
DHT22 has 4 leads,(3 active) AM2302 has 3 wires, yellow maps to Data pin 2 additional
connection info here:
https://learn.adafruit.com/dht/connecting-to-a-dhtxx-sensor
Q- What is the difference between temperature and heat index?
A- "Temperature is an absolute value while Heat index includes humidity to relay how it 'feels' to
us. "
A-See lab 1 step 13 below (with pictures)
Q-What wireless protocols does The Adafruit Huzzah ESP8266 board support?
A-Per Adafruit the Huzzah ESP8266 board supports 2.4Ghz Wi-Fi 802.11 b/g/n along with WEP,
WPA/WPA2, make sure and disable TKIP on router, as that seems to be a common issue with
WPA2 connections.
Q-Where do I find the Arduino IDE plugin for Visual Studio
A-In VS go to Tools/Extension and Updates and select on the left side Visual Studio
Marketplace. Now search for Arduino IDE. It is by Visual Micro
Q-How do I get Line numbers to show up in the Ardunio IDE 1.8.5 Compile/Sketch window ?
A-Select - File, Preferences, check the box to “Display line numbers” , ok in lower right.

Q-Where is the free Trial of Azure, however you will need to validate and sign up for the free
account with a credit card.
A-https://azure.microsoft.com/en-us/free/
Q-Where can I check the status of Azure Services Globally
A-https://azure.microsoft.com/en-us/status
Q-How do I make sure to minimize cost associated with Azure trial after the labs?
A-Delete the “Resource groups” that were created for the labs, or review each of the resource
services and pause or shut them down. See graphic below
Q- What licensing is involved if you decide to use Raspberry Pi in commercial application? Are
there any royalties?
A-You cannot use the words Raspberry Pi to promote your product without permission.
Raspberry Pi is trademarked. If you’re making a product which requires a Raspberry Pi to run,
we don’t ask you to buy special permission or licenses from us to use it. All we ask is that you
include the words “Powered by Raspberry Pi” somewhere on your packaging. If your business is
successful, we’d be very grateful if you could consider donating a small portion of your profits to
the Raspberry Pi Foundation – but that’s all, and if you choose not to do that, that’s fine too.
However, you will have to ensure you follow the terms of the software licenses for any software
you embed in your product.
The Compute Module1 might be a better solution for industrial application-
https://www.raspberrypi.org/products/compute-module-1/
Q-Can you discuss when a device needs to be FCC certified ?
A-Raspberry Pi is listed as Raspberry Pi Trading Ltd - https://fccid.io/2ABCB-RPI32 The FCC
Declaration of Conformity or the FCC label or the FCC mark is a certification mark employed on
electronic products manufactured or sold in the United States which certifies that the
7 | P a g e

electromagnetic interference from the device is under limits approved by the Federal
Communications Commission.
Q-Is it possible to have a list of links, For example resources of the Fona chip, where to buy,
tutorials, etc
A-https://www.adafruit.com/product/2542
https://learn.adafruit.com/adafruit-fona-3g-cellular-gps-breakout/overview
https://learn.adafruit.com/adafruit-fona-3g-cellular-gps-breakout/downloads
Q-I connected the LCD (provided in the kit) to the Pi. it works well with the noobs but once I
installed the Win 10 IoT core, the LCD monitor does not work. (look like it does not support the
initial screen resolution for the Windows Image) I connected my HDMI Desktop monitor and it
works well. Is there a way to configure windows to support the LCD provided in the kit?
A-There were a number of different Touch Screen displays sent out from Adafruit. The work-
around for display resolution is this:
Edits to the config.txt files, both Win10 IoT and Raspbian OS. The displays worked properly with
both OS’s after this change.
(+AR1100 Touch Controller - 7” 800 x 480 HDMI Backpack)
-Win10IoT
add /edit 4 lines into the config.txt of the following folder on the SD Card
H:\EFIESP\config.txt
Under “# Video”
hdmi_group=2 # Use VESA Display Mode Timing over CEA
hdmi_mode=87
hdmi_drive=1

Q- Please elaborate on the differences between Azure IoT Edge and Azure IoT Stack And their
respective cost models
A- Azure Stack is really running Azure on multiple servers / racks on your hardware. Imagine a
customer who has a regulatory need to keep data in country and there is no Azure in that
country. Azure IoT Edge is much smaller, imagine a Pi, where we get data from sensors in the
"factory" and do edge summarization then send to the cloud.
Q- I need to get budget approved on a yearly basis even if i get billed based on usage. Do you
have recommendations on how to use the iot calculator to estimate costs? Which exact
functionality and which tier to select.
A-To calculate Azure IoT Hub, it is pretty simple. # messages, frequency, size of messages etc.
Instead, I suggest looking at the IOT Suite, which includes other components, functions, web,
stream, etc.
Q- Is there another communication method with a longer range than wifi but maybe up to 1/4
mile at most?
A-yes, see this temp,humidity sensor from NCD.IO https://store.ncd.io/product/industrial-long-
range-wireless-temperature-humidity-sensor/
Q- How do you keep up on the cutting edge of sensor tech? What are good resources?

Q-After adding the libraries, there are still compiler errors.
A-You may have accidently added the wrong libraries or versions. To remove libraries from the
installation, they are stored in the following directory:
“C:\Users\username\Documents\Arduino\libraries” You can simply delete the eroneous
directories and add correct libraries from the lab guide, from within the Arduino IDE Application.
Q- initial verify/compile/upload is painfully slow.... (if baud rate set to 9600 in sketch?)
A- The first project can take a while. Just be patient, subsequent ones will be much faster. (set
baud rate to 115200 for best results)
Q-How can I tell what my MAC address is of the ESP8266
A-In Arduino, you can use the command: String myMAC = WiFi.getNetworkInfo.macAddress();
which will return a String of your MAC address. Alternatively you can log on to your
router once connected -look for wifi client attached – default is ESP_XX XX XX (Last three of
MAC Address) example MAC – 5C:CF:7F:3A:19:E8 (Host appears as ESP_3A19E8)
Q- Where are the drivers located for the ESP8266, they are copied here on installation of
Arduino IDE ( mine -with a clean build of Win10, installed drivers just after Arduino)
A- C:\Program Files (x86)\Arduino\drivers
Q-Is there a MAC version of Device Explorer / IoT Explorer?
A-Microsoft provide a Node.JS version here: https://www.npmjs.com/package/iothub-explorer.
Alternatively you can look at: https://connectedstuff.io/2017/03/16/cross-platform-iot-mac-
part2/
Q- how do I run device explorer? I just installed it?
A-on Win10 Start – (folder)Azure IoT Hub\ Device Explorer
10 | P a g e
© 2017 Microsoft
File location: C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Azure IoT Hub\Device
Explorer
Q-IoT Hub F1 Tier has the following capabilities (8000 messages per day)
A- the F1 (free) tier will let us send a message once every 11 seconds to get 7854 messages a
day, message meter size 0.5 KB
Q-is IoT hub offered in differnet capacities and pricing options ?
A-Yes. https://azure.microsoft.com/en-us/pricing/details/iot-hub/
https://azure.microsoft.com/en-us/pricing/calculator/
Q-When the number of messages reach to the limit of IoT hub, is there a way to clear the
message from IoT Hub manually instead of relying on my reader app?
A-No..
Q- "What is the purpose of the unified sensor? How come not just the dht22 sensor?"
A- It is the Adafruit sensor library and provides support for various sensor devices
Q- Is there a way to operate a device in "temporary offline" mode: collect data throughout the
day and then sync up when needed? For example like UPS delivery guys use while delivering
packages, then back at the warehouse in the evening upload all that data to the cloud.
A- Yes, we do expect to have "infrequently connected" devices as part of an Azure solution
topology.
Q- I am getting "Fetching NTP epoch time failed! Waiting 2 seconds to retry."
A-This is indicative of an internet connection issue. Make sure the device is connected and the
connection unimpeded by firewall, etc.
Or the most common causes are:
NTP uses UDP Port 123, is this blocked.
Is your device behind a captive portal and does not have real access to the internet?
11 | P a g e
© 2017 Microsoft
Can your device resolve the NTP host names via DNS?
Some issue in the SSL library. Please make sure that you are using the latest libraries.
The firmware needs to be updated on the Arduino Huzzah
Q- There's a mention of multiple consumers and things using the same "consumer group". What
is that?
A-A consumer group will give each application their own view of the event stream.
You can have different apps 'consume' the data from IoT Hub. This ensures that a given
consumer group will get a message once and only once. More info here:
https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-features#consumer-groups
Q- Is there a planned support for FreeRTOS?
A-Already support for many languages under FreeRTOS
https://azure.microsoft.com/en-us/blog/benefits-of-using-the-azure-iot-sdks-in-your-
azure-iot-solution/
Q-Where are the Arduino Azure Libraries that are installed, Are they on github? Where
are they installed when downloaded?
A-https://github.com/Azure/azure-iot-arduino
Q- When creating a power BI account for the LAB that works, however, when I try to
login the browser wants to use my azure account.
A-Try opening in a private browser session and log in to Power BI
Q- What are the implications of deleting your IoTHub for any existing IoT devices?
A- Will you need to change the connection string in the devices if you plan to re-create
the hub again with the same name in the future?
Q-The name of my output blob contains a “-“,how can I change or rename it?
A-You will need to delete the blob and recreate it with only regular characters, letters
and numbers.
Q-where can I find sample data sets for powerbi
A-You can review many sample data sets here: https://docs.microsoft.com/en-
us/power-bi/sample-datasets
Q- Are we supposed to keep our device running against IoT Hub all night, so we have
some good data for tomorrow's labs?
12 | P a g e
© 2017 Microsoft
A-Yes, we will use the data collected, sent to Azure for future labs.
Q-Can the Windows IoT OS run on the Pi Zero? If so, with the reduced compute capacity from
the Pi 3, how functional is it?
A-Unfortunately Windows IoT Core will not run on the Pi Zero.
Q- Why are LED and Blinky App not in sync? "After numerous compiles and reboots it worked!
Its not very consistent/stable. Is that normal.. ?
A- The Two may not be in perfect sync. The monitor and the LED have different refresh rates.
Q- Forgot my deviceportal password.. anyway to reset it ?
A- The easiest way is to reflash. but, there is a possibility that your password is not provisioned.
Please try the default username /password , Administrator/ p@ssw0rd
Q-is there a way in Azure Portal to change the IoT Hub from F1 to S1 Pricing Tier?
A-F1 is kind of an exception. So you can't scale from one of the paid SKU's to the free one, but
also not from (free)F1 to S1. You can always document the name of the hub, the device and the
keys. Then delete the hub as an F1 and create it as an S1 and setup the devices with matching
keys.
Q- The Raspberry is shipped with an USA 110VAC power supply, it doesnt fit here in
Holland !
A-Make sure you have Power Adapter / to convert 120VAC Transformer Power for your
country’s input requirements. Travel Adapter Transformer ? Do you have a Micro USB
power adapter of (2A minimum power output) for a Mobile Phone perhaps?
Q- How to mass produce IoT (ex. Fether) devices with the same code and submit them
to different Azure costumers accounts?
A- Device Provisioning Service (https://docs.microsoft.com/en-us/azure/iot-dps/) allows you to
boot all devices to a single "source" and then from there, it will provision them to the correct IoT
Hub.
As for mass producing Feather devices, you can just upload the code (*.bin) via serial to them.
Q- Can I have the Azure REST API docs reference?
A-initial insights: https://docs.microsoft.com/en-us/bot-framework/rest-api/bot-
framework-rest-connector-api-reference
Q-how can I add a driver to Win IoT Core ?
A- https://docs.microsoft.com/en-us/windows-hardware/manufacture/iot/add-a-driver-
to-an-image

Q-Way that "Visual Micro" in the Visual Studio Marketplace that you where showing us
yesterday to compile Arduino code in VS2017?
A-
https://marketplace.visualstudio.com/items?itemName=VisualMicro.ArduinoIDEforVisua
lStudio
Q-Does the "Windows IoT Remote Client" work? I've tried enabling it under "Remote"
on my device, but it's not working.
A-It does not work on RPi3, as there is no GPU support in Win10 Core for the Pi3 (yet).
I believe this works on Pi2 and other devices that support GPUs, and hopefully will
soon on Pi3 as well.
Q- Will these sessions be transcribed or captioned for those of us with hearing
problems?
A- Yes - Skype Broadcast automatically captions within the tool. You can turn it on by

Q- Thoughts on power management and using things like small solar panels for
mounted devices?
A- You need a combination of compute and networking hardware that are optimized
for low-power or battery performance. The RPI3 isn't the best example of this, but
MCU-powered devices like the Huzzah along with various narrowband IoT
communications hardware would make a good case -- the combination of super
capacitor / battery / solar is then very viable.
Q-I am having problems logging into my RPi3 what syntax should I use ?
A- http://IPV4_address:8080 computername\administrator and "p@ssw0rd"
Q- How do I flash the IoT Core ISO in the IoT Dashboard without re-downloading? I
downloaded the ISO directly from the link provided in the laptop setup documentation.
A- you have to mount the iso and install the msi inside.
After installation you will find the flash.ffu which is the RPi image here: c:\Program Files
(x86)\Microsoft IoT\FFU\RaspberryPi2\.
in the IoT Dashboard you have to select in Device Type "Custom" and Browse for the
flash.ffu.
Q- how long should it take to boot up the Pi with the Windows IoT Core OS?
A-About 2 minutes based on speed of the Pi and SD Card.
Q- where to get the twin device explorer?
A-https://github.com/Azure/azure-iot-sdk-csharp/tree/master/tools/DeviceExplorer
Q- I see the AllJoyn screen. What are other components defined by OCF or OPC UA are installed
or can be installed on Windows 10 IoT RPi3 device
A-OPC/UA is implemented in .Net. More info here: http://opcfoundation.github.io/UA-.NET/
Q- Device Twins looks great to work with, but what about devices that are connected to external
cloud services like LoraWAN/Sigfox which is then connected to IoT Hub, can Device Twins still
be used ?
A- Yes. Devices need to be connected to Azure IoT Hub to take advantage of this functionality -
- they can connect via a number of different means, including LoRA, Sigfox, etc -- this isn't the
limiting functionality as they are just means of providing different ways of connecting the cloud
Q- Where can I find docs on What objects available to Azure Functions Triggers and queries for
Stream Analytics job?
15 | P a g e
© 2017 Microsoft
A-Here you'll find documentation, samples and a number of quick starts to try yourself:
https://docs.microsoft.com/en-us/azure/azure-functions/
Q- What is the difference between the etag in the twins properties and the tags that we added
in the lab?
A-a tag is for information purposes only (e.g. where is a device located). a twin property is a
means to communicate with the device (even if it is disconnected). A device can subscribe to
changes of desired properties so it will be notified about them. More info here:
https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-devguide-device-twins
Q-Can I run Device Explorer and Stream functions simultaneously?
A- Yes. You can run Device Explorer and Stream and Functions at the same time if using
different consumer groups.
Q- Hi Ted, How many languages can be processed by speech & language cognitive
services? What regions of world are covered?
A-https://cognitive.uservoice.com/knowledgebase/articles/954931-current-supported-
languages-for-each-api
Q- Can the facial recognition also work with depth like Windows Hello to make it more
secure and not spoof a person with a picture in front of the camera?
A-Hello is a different technology and FACE can not interact with. It only returns x and y
values no z values. So no depth for FACE, witch makes it a nice to have but not secure
at all for any security application.
Looking at the JSON return on this website (same used by Ted), This particular API
doesn't use 3D data -- but local APIs like Hello do.
https://azure.microsoft.com/nl-nl/services/cognitive-services/face/
Q- Don't see the Local Machine or Remote Machine options when trying to run/debug
in Visual Studio, any thoughts?
A- Click on the standard toolbar Options and Add the Button "Debug Target" to the
Toolbar, Don't choose DEVICE, but choose REMOTE MACHINE.

5.5.2 Q and A for the Lab and SD card issues
Q- I tried writing the IoT Core image via the IoT dashboard twice and keep getting a "Failed to
provision..." error of some sort at the end. The SD card looks like it was written to and has
several partitions. Is this still a bad image write?
A-SD card recommendations – 16G Micro SD card class 10 for win10 IoT Core (what ships in the
kit from Adafruit is an 8G Micro SD card)
21 | P a g e
© 2017 Microsoft
if your config didn't write, but you have a vanilla IoT Core image written to your card, the default
login/password is "Administrator/p@ssw0rd" This will work in the device portal and when
connecting to the device directly via keyboard and mouse
5.5.3 Clearing partition table of an SD Card
In lieu of using your Windows desktop to perform these tasks.
You can also us a tool from https://www.sdcard.org/downloads/formatter_4/index.html
For MAC or Windows OS’s.
Here is how it can be done from your Windows desktop/laptop
Cleaning the partition table from an SD card, in the event of problems with IoT Dashboard.
** approach with caution
It is imperative that you select the correct disk.
Insert the Micro SD card into one of the SD card adapters that shipped with your Adafruit kit
into either an SD card slot on your computer. In the event you do not have an SD card slot on
your computer, use the USB Micro SD card reader that was part of the Adafruit kit.
Press – Windows key, Type “CMD” for (command prompt) (enter)
At the command prompt Type “Diskpart” (enter)
You will be prompted, by User Account Control.
“do you want this app to make changes to your device?”
select (Yes)
Type “list disk” – to display a list of the disks attached to your computer.
– Disk 1 - is my SD Card slot in this example.
(**Caution – you can purge your Primary OS disk if not careful here **)
22 | P a g e
© 2017 Microsoft
Type “select disk 1” to perform actions on this disk. (note size- MB to identify)
• **Note Disk 1 is now the selected disk.
Type ? (enter) to see available commands.
We are going to “Clean” the selected disk in this instance.
To get help on any of these commands type “help clean” (enter) for example
23 | P a g e
© 2017 Microsoft
With Disk 1 selected, type “Clean” (enter)
Type “exit” (enter) at the Diskpart command prompt to exit the application command prompt.
From this point you can use either NOOBS or IoT Dashboard to install the Win10IoT core image
back onto the SD card.
5.5.4 NOOBS 2.4.5
One of the Adafruit SD cards comes pre configured with NOOBS 2.4.5 already on it. If you
desire to recreate or restore the SD card. It is straight forward.
Download the .zip file here: https://www.raspberrypi.org/downloads/noobs/
Format your SD Card with a Fat32 partition
Windows key, type “diskmgmt” (enter)
Right click on “disk 1”, or your SD CARD, create a “New Simple Volume”
“Next” at Wizard, accept the defaults *(Size) 7550 MB.
“Next”, Assign a drive letter
24 | P a g e
© 2017 Microsoft
Format the file system as FAT32
“Next”, “Finish”
At this point you can extract the NOOBS 2.4.5 .zip file to the SD Card \root partition.
Right click on the “NOOBS_v2_4_5.zip”, extract to E:\
25 | P a g e

Once completed, eject the SD Card and remove Micro SD card, insert it into your Raspberry Pi.
On First Boot you will be given choice of OS that you would like to setup the SD Card with.
Raspberian is one of the choices.
With a Wifi or Wired connection on the RP, you can also download and install Windows IoT
Core.

d. ASP.NET and web development
e. Azure development
f. Node.js development
g. Data storage and processing
h. Data science and analytical applications
4. The total download for these options is around 24+ GB and installation takes a bit of
time to complete, so please do this prior to start of workshop.
5. After installation, launch Visual Studio to finish configuration of the tool.
a. Check for any updates using Tools > Extensions and Updates
5.5.7 Lab5 step 9
Q- Do we need to run Visual Studio in Administrator mode?
A- No, you don't have to. It can be run in user mode
Q- Running Visual Studio Community w/ Windows Universal installed on Win10 Pro (w/ latest
updates), when I open the 'HelloWorld' MainPage.xaml it gives an error 'VS requires a newer
version of Windows to display this content - Please update to UAP (10.0.16299.0) or later'. Is
there something else I need to install?
A- If you create your UWP, there is a minimum and a default SDK version that you can specify. If
both are on 10.0.16299.x but you are not running the Fall creator's update, it means that the app
cannot run on your development machine. However, if you select ARM, you should be able to
compile and deploy to the RPi.
5.5.8 Lab5 step 16
there is a typo in the Lab Documentation.
Please copy the “Blinky.sln” (HelloBlinky does not contain "BlinkyIOT.sln". )

5.6.1 Lab 6 step 10
Q- We put in a locate on.. but what happens when IoT core is restarted? does it receive the
location from the cloud or does it store it locally?
A- It is not actually reading location. The backend sets the location for the device, so nothing
really happens with location. The IoT core Configuration data is preserved on the Local SD card
within the Raspberry pi for subsequent restarts.

Q- What techniques can be used to secure the data when cognitive solution is deployed to the
edge? Provided by default or needs to be designed in?
A-Edge uses Docker. it is up to the developer to implement edge level security such as
encryption.
Q- Please give examples of IoT Edge devices.
A-IoT Edge is our SDK for creating appliances that sit at the edge of a network and provide
hybrid connectivity between the premises and cloud, and that can do things like stream
analytics, run machine learning algorithms, etc. These devices frequently act as gateways --
communicating with numerous sensors and devices on the local network, doing some kind of
pre-processing to the data, and deciding what is sent to the cloud or what needs additional
processing in the cloud. They can also take corrective and notification steps, etc. More info
here: https://azure.microsoft.com/en-us/services/iot-edge/
Devices that can run this SDK are varied -- but some typical devices might look like the
following from Dell and HP:
