Posted on by VenkyKrishnan1 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

    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.

    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.
