2020 Edge Computing/IoT Survey

The Internet of Things

This survey is about two linked problem spaces: edge computing and the Internet of Things. The purpose of these questions is to understand how your experience building software affects how you think about edge computing and the Internet of Things — whether or not you have deliberately worked in either specific area.

We will publish a full analysis of the aggregated survey results in our upcoming Trend Report, scheduled for release in mid-December. Your answers will help developers and other IT professionals build and deploy more scalable, more performant, and less fragile software.
2. Have you worked on any projects that you would consider IoT? *This question is required.
3. Please indicate your experience according to the following statement (check all that apply):

I have developed software that controls or otherwise interacts with...
4. How has the software that you've worked on interacted with the following kinds of physical data? *This question is required.
Space Cell Directly processed sensor signalsProcessed data downstream from sensorNone
Light
Sound
Temperature
Pressure
Moisture
Atmospheric pressure
Electrical current
5. Have you written software that runs on devices that communicate by some means other than a TCP/UDP or some other transport layer that sits on top of the Internet?

Consider any communication protocol in your answer, very broadly construed. For example, writing code that talks Bluetooth or Zigbee counts as "Yes'" — but so does writing a DSP for sensor data, an audio driver, or code that regulates wattage over a coaxial cable or photons over fiber. These also involve transmitting information without depending on an "underlying" Internet. *This question is required.
6. Please rank the following technical challenges to IoT (top = most challenging, bottom = least challenging):
  Order the items from the following list. First select an item with the spacebar to show a menu of possible ranking positions. Next, click a ranking position to order it in the ranked list. Note the menu will display more ordering options as you add items to the ranked list.
8. If you have worked with any of the following protocols, please rate them in terms of power and ease of use:
Space Cell PowerEase of use

CoAP
MQTT
AMQP
