Get an error when I Deploy Demo demo environment: Says reached ARM Core limit in your subscription

Posted on by 10

In my attempt to Deploy Demo (in LCS), I clicked on Cloud Hosted environments.

When I try to Deploy environment, I get an error modal that says

You’ve reached the ARM Core limit in your subscription. You have [4] total cores, [4] cores available, and this deployment needs [8] cores. You need [4] more cores. You can either delete some existing topologies or, increase the Azure ARM Core limit for your subscription.....Screenshot-2023_2D00_04_2D00_08-at-3.45.20-PM.png

How do I resolve this? I have an Azure subscription that I just added for this demo. I dont believe I have configured any ARM Core limits.

How do I get this demo instance deployed?

thanks

    Hi Venky,

    You can reach out to Microsoft Azure Support and ask to increase the number of cores for your subscription. This is something that can be changed by Microsoft.

    Hello Venky,

    The purchase Azure subscription can Only accommodate 4  CPU cores. But the VM you selected on LCS says otherwise, hence the error.

    You can check this https://azureprice.net/ to decide what can go with your Azure sbscription while taking into consideration the region.

    For instance, if you okay with deploying in West US, I will advice you select D12_V2.
