Azure Batch out of capacity in North Europe

Question

We're getting the following error on some of our Azure Batch pools in the North Europe region:

Code: BatchOutOfCapacity

Message:
Azure Batch is currently out of capacity in this region. Please retry later or try in a different region.

We aren't reaching our Azure Batch quotas, and the error seems pretty clear that it is the Azure Batch service as a whole rather than our account that is having capacity issues.

I have a few questions about this:

• Is it due to our choice of VM type (Dv2), and therefore would switching to a different VM type help?
• If so, is there any way to get insight into the availability and capacity usage of different VM types in different regions, so that we can make an informed decision about what to switch to?
• If we do nothing is the problem likely to go away as MS adds more capacity, or is it likely to get worse due to new Dv2 instances no longer being added?

Answer 1

I got official word on what the issue was here:

• There’s a bug that sometimes means the BatchOutOfCapacity error is returned, even though the resize was successful.
• Resize operations are not affected and current nodes should equal target nodes, but the error is returned instead of success.
• A fix will be deployed in the next week or so.

I think the fix has now been deployed.

Hey @James Thurley ,

Yes you can try using a VM with a different SKU to see if there is capacity for that VM. As for getting insight into the general availability of VMs in a region you would need to open a support case. I know support teams have access to that information and would be able to guide you but datacenter capacity is not shared publicly.
