  • Hi Hury, upto some extent! But my question is- with respect to above screenshot. if per instance charge is X per month, does keeping minimum instances to 10 would charge me 10X per month plus charges of maximum burst with respect to its utilization? – Bikram Jan 08 '20 at 05:12

For your question, I summarized the pricing rules below for your reference:

Azure Functions Premium plan provides the same features and scaling mechanism used on the Consumption plan, but the difference is we can set the Pre-Warmed instances.

Premium plan can avoid cold start by setting the Pre-Warmed instances, for example we can set 1 instance for Pre-Warmed(but smaller than minimum instances size which you set), then if the function app hasn't been requested for a long time, we just need to pay for the warm instance. The price is shown as below:

enter image description here The EP1 plan is 3.5GB for each instance, so we can calculate the price.

While the function app is requested, then it will billed on a per second basis based on the number of vCPU-s and GB-s(based on the number of the instance which your function app uses on a per secnond).

Hope it would be helpful to your question~

I got the answer: here

"You are charged for each instance allocated in the minimum instance count regardless if functions are executing or not."
