Quotas and limits for the Azure Batch service

This article lists the default and maximum limits of certain resources you can use with the Azure Batch service. Most of these limits are quotas that Azure applies to your subscription or Batch accounts.

If you plan to run production Batch workloads, you might need to increase one or more of the quotas above the default value. If you want to raise a quota, open an online customer support request at no charge.

[AZURE.NOTE] A quota is a credit limit, not a capacity guarantee. If you have large-scale capacity needs, please contact Azure support.
