Hi everyone do you know what the quotas and limits are on functions? I need to provision about 120 Functions on a Isolated V2 App Service environment. I've been reading this, but I've not been able to understand very well, specially when unbouded is expresed. In the same way, I need to provison an Event Hub Namespace with 150 Event Hub's. Starndard Tier is not enough for this. How ever, I read that Premium tier can provision 100 Event Hub per PU, so provisioning an Event Hub Namepsace on Premium tier with 2 PU will enough (capacity for 200 Event Hub) ... ¿Am I right with this rationale? I read this about Event Hub Regards

    @Jona Thanks for reaching out.

    For Azure function Isolated V2 App service plan there is no hard limit as such and when you see "unbounded" it means that there is no specific limit set for that particular resource or feature. This means that you can use as much of that resource or feature as you need, subject to other limits such as the overall resource limits for your subscription/max number of instances for a specific plan etc.

    For your Event Hub quota query, you are correct that the Premium tier of Event Hubs can provision up to 100 Event Hubs per Processing Unit (PU). Therefore, if you provision an Event Hub Namespace on the Premium tier with 2 PUs, you will have the capacity for 200 Event Hubs. However, keep in mind that there are other limits and quotas for Event Hubs, such as the maximum number of partitions per Event Hub and the maximum size of an Event Hub. You can find more information about these limits and quotas in the Azure Event Hubs documentation.
