Hi,
I am new to Azure and trying to understand the limits for Azure Functions. I need to deploy container based Azure functions.

As per the following documentation
https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/azure-subscription-service-limits#azure-functions-limits
It has been mentioned that for "Premium Plan", "100 Function Apps" per plan.
But below, it is also mentioned that "There's currently a limit of 5000 function apps in a given subscription."

Does this mean that only 100 function apps with premium plan can be provisioned?
What if I need to provision more than 100 Azure Function apps? Is 100 a soft limit and 5000 a hard limit?
Is my understanding correct or can unlimited Azure functions be provisioned?

I have worked with AWS Lambda before and know that unlimited AWS Lambda functions can be provisioned. I have a similar requirement with Azure functions as well and therefore I would like to understand if the same is also possible with Azure Functions or not?

Also, is it possible to allocate only 1 GB memory to an Azure function provisioned on "Premium Plan"?
As I can see in the documentation it is mentioned 3.5GB memory for Premium Plan.

    Hello Dhruv.Parekh,

    Thanks for your question.

    100 function app limit applies specifically to each Premium Plan, not your overall subscription. You can create additional Premium Plans to scale out.

    5000 Function Apps per Subscription is a hard limit across all plans in your subscription.

    Memory Allocation: fixed maximum memory is 3.5-14 GB for premium plan depending on the SKU. So no you cannot allocate 1GB
