Azure IoT Edge
Azure IoT Edge moves analytics and logic out of the cloud and onto your on-premises devices. Using a cloud interface, you can deploy either Azure service logic or your own code to devices without having to physically access them. And offline capabilities mean that you can extract business insights anywhere, without worrying about maintaining constant communication with a cloud service.
More details about the services are available in the documentation.

Code sample for identity translation pattern.
If the development team is busy, some guidance on how does the module(who understand native protocols and gives device identity) receive the connection string will be helpful. Hard coding connection strings is not is not an option.

Make IoT-Edge (V2+) usable (again) in products which require both OnPrem and OnDemand deploy
In many industries (e.g. medical, energy, aeronautics) companies must produce products that can also be installed in environments where no internet connectivity is available/permitted. These same products however, are also often installed in places where they can leverage cloud (OnDemand) capabilities. If IoT-Edge ist to be applicable for such products, it must (by design) provide for:
1. Installation from download or USB-stick including configuration via config file or local API (as did Edge V1)
2. Provide and abstraction layer to the external communication (as was done via Edge V1 Modules) enabling a configurable routing to use OnPremises endpoits (REST) or…48 votesHi Richard, item #3 has been addressed with the public preview of extended offline feature work. You can find out more about it at the blog post below. The rest of the issues you raise will take longer for us to add to the product.

Support X.509 certificates in IoT Edge for Raspbian (Linux) and the Device Provisioning Service (DPS)
We are using a Raspberry Pi Zero W for a large-scale IoT sensor rollout. Our plan is to use IoT Edge on Raspbian (Linux) to run our Python software on the devices and leverage the IoT hub to deploy our code via modules to our devices. We also want to use the IoT hub Device Provisioning Service to further automate the rollout of newly added devices. The goal is to make this scalable to 1.000 devices as a Proof of Concept, and in a production phase scale up to 50.000-100.000 devices.
We've tried to follow the tutorial by Microsoft to…

Support Ubuntu Core
Add Ubuntu Core as supported Operating Systems. It is becoming a preferred "secure by default" OS which is preinstalled on many IoT Gateways. E.g. Dell Edge Gateways
30 votesWe are aware of this OS and want to get to it; however CentOS 7.5 and Yocto are currently higher on our priority list.

Azure blob file upload
We are planning to upgrade an existing production application from V1 to V2. In addition to streaming data (as messages to Azure IotHub), we also upload hourly aggregated data to Azure blob store. Can you share approximate time-lines when V2 can have support for Azure blob upload?

Need a way to see a message as it is routed through the Edge
An IoT Edge message correlation id should be provided so that specific message workflows can be diagnosed via module logging.

IoT Hub device and module twins limit.
There is limit of 8KB limit for IoT Hub device twins. What’s the limit on module twins? How much total size allowed for both device twins and module twins? Is any plan to enhance the size of both twins in GA or later release?
18 votesThe limit for module twins and device twins is the same: 8KB per section. We do have plans to increase the size limits but can’t disclose a date yet.

C2D Messaging
I know direct methods are possible but sometimes you just want to have a queue of C2D messages which are delivered to devices when they come online. Direct methods only work when a device is connected and it would require some effort to implement the aforementioned scenario. Also one would need some routing logic to deliver those messages to modules.

Removing unused modules from IoT Edge devices
I am successfully able to add and remove custom modules from a deployment. However, I notice that modules that I remove through a deployment, remain on the device, occupying space. So at some point, the device's storage will get filled up with junk (outdated or unnecessary modules), leading to a system crash.
This is the response I received from Microsoft - "Thanks for your feedback @baharw . That is by design - you can easily integrate a direct method for example that would be responsible to remove all unused docker images on your edge device. I nevertheless suggest that you…

Progress bar for deployment of modules
For development, testing and monitoring purposes it would be great if there would be more information about the progress of a deployment, especially on the Edge device itself. One can look at the logfiles for the start and finish of a deployment, but I would like to know more than this. My suggestion would be to see the container in the 'iotedge list' with status downloading (42MB/100MB, 42%), but I'm open to any other form of monitoring the progress of the deployment.

Document how to connect Azure Sphere Device as Downstream Device to Edge
It would be great to connect the new Azure Sphere to the IoT Hub on Edge to use Sphere in a Transparent Gateway Scenario

BLE Sample
Will a BLE sample be available?
As I understand, it will require the module container to run in privileged mode to gain access to hardware devices... Is this supported?

IoT Edge Module deployment limit
Currently there is a limit of 10 modules (includes agent, hub) to be deployed to IoT Edge device. What is the plan for module deployment limit for GA release? The reason is the solution we are working demands multiple (more than 8) peripheral integration at device level and we see that each Edge module could represent the peripherals. Also, please share tentative plan of GArelease?
12 votesThe limit has indeed been raised to 20. We’re interested to learn about scenarios that require more than 20 modules.

Hierarchy possibilities for edge devices.
The purpose is to have for example 5 incoming sensors in the 'sensor' edge device where we can do some calculations on the edge. The output goes to another edge device, where again we can do some calculations on the edge with input from other similar 'sensor' edge devices. The last edge device in the chain will send the data to the IoT Hub.

Remote login to IoT Gateway
If an IoT Gateway is deployed in the industrial plant and if some application crashes in Gateway or some need of login to the gateway.
In that case, Azure IoT edge should allow users to remotely log in to the IoT gateway using ssh/telnet. This will very easy to monitor the status and debugging/maintenance.9 votes -
More options, or configuration parameters, of storeAndForwardConfiguration
storeAndForwardConfiguration has a parameter, timeToLiveSecs to specify offline period to retain data.
Preferable to add following 3 parameters to storeAndForwardConfiguration
1. Limit the amount of disk usage to be used for SnF feature.
2. Specify the directory/path of storage for SnF feature
3. Flush un-forwarded messages in SnF memory out to specified files9 votes -
Need a way to distribute communication at edge devices when offline with IoT hub
During offline with IoT hub, is it possible to have a mechanism at Edge device to distribute the messages among other Edge devices? This will help to address a scenario were one Edge device needs to share message/information with another Edge device as there is no cloud data storage share available due to
connectivity issue.8 votes -
Example of C based module for Transparent gateway
Can you please add code sample for transparent gateway use case? We use the v1 modules implementation for communication with other
network protocol based on this example: https://github.com/Azure/iot-edge/blob/master/v1/samples/ble_gateway/iot-hub-iot-edge-physical-device.md. We would like to move the solution to v2. Modbus module is not very useful for our solution. Thank you.6 votesWe are planning on providing an example of this for the SensorTag which speaks BLE. That said, it probably won’t be available for a couple months so it’d be great if you created an example as well.
Please see the following comment where we discuss gateway scenarios a little more.

(Cloud-triggered) IoT Edge Runtime Updates
Provide a way of an (automatic) cloud-triggered update mechanism for the IoT Edge Runtime through IoT Hubs Device Management. Providing update capabilities not only for the containers but for the runtime and even the underlying OS is crucial for IoT Scenarios.
