Hi Stanley Ramakrishnan ,
Thank you for reaching out to us on Microsoft Q&A forum.
We understand from your query that you are experiencing an issue while trying to create an Azure Batch Pool due to reaching the Pool Quota.
Please follow these steps to create an Azure Batch Pool: create a Batch account and run a job
Note: In some regions and subscription types, quota restrictions might cause Batch account or node creation to fail or not complete.
In such situations, you can request a quota increase at no charge. For more information, see Batch service quotas and limits
If you already have a Pay-As-You-Go subscription, you can request a quota increase.
If you are using an Azure free trial subscription, you are unable to request quotas and limits. If you have any further queries, do let us know.
