How to increase the 100 IoT Edge automatic deployments limit in a an IoT Hub Azure service?

Question

Hi I'm getting the ConfigurationCountLimitExceeded error when trying to deploy a new deployment.

ERROR: {'Message': 'ErrorCode:ConfigurationCountLimitExceeded;Number of deployments exceed the maximum quota 100 for this IotHub.', 'ExceptionMessage': 'Tracking ID:xxxG:0-TimeStamp:xxx'}

I have tried increasing the hub's size (from S1, 1 unit to S2, 20 units) but the error persists. Is there any way to increase the 100 deployments limit? Regards

Hi Nahuel ,

Encountering the "ConfigurationCountLimitExceeded" error signals surpassing the 100-deployment limit for your Azure IoT Hub. Despite scaling up the hub's size, the error persists. To address this, reach out to Azure Support or your representative for a potential quota increase. Meanwhile, assess deployment frequency, optimizing to reduce unnecessary deployments. Monitor deployment history for effective management. Explore Azure portal options for deployment limit adjustments. Stay updated on Azure documentation for the latest guidance. Efficiently managing deployments ensures smooth operations within the imposed limits. Regards,

Hi @Nahuel Pablo Carducci Greetings! Welcome to Microsoft Q&A forum. Thank you for posting this question here.

The maximum allowed edge deployment limit is enforced on the IoT Hub tier level [per SKU] and the number of units available in your tier does not impact this limitation once the maximum allowed limit of 100 has reached. Unfortunately, this is a hard limit set on the IoT Hub service level and cannot be overwritten.

Please refer to the following section of the article where you can find the IoT Hub Operational limits. I am adding the image with the limits here for your reference.

To overcome this limitation, you may have to consider deleting a few of your old deployments which can be accessed from the Configurations + Deployments tab of the IoT Hub through the Azure portal.

Hope this helps! Please let us know if you have any additional questions or need further clarification.

Hello @Nahuel Pablo Carducci ,

welcome to this moderated Azure community forum.

The current deployment limit is 100 deployments indeed:

100 deployments (including layered deployments) per basic or standard SKU hub. 10 deployments per free SKU hub.

This is the same for all basic and standard IoT Hub tiers and unit sizes.

Sometimes Azure (portal) limitations can be changed via an Azure support ticket (like the maximum number of Azure IoT Edge modules). Perhaps this is also applicable to your challenge.

If this is not the case, you need to rethink your layered deployments strategy and start deleting those not in use anymore.
