Azure SQL databse pricing tiers changing automatically

Question

Azure SQL databse pricing tiers changing automatically

Nasir Siddiqui 25

Hi ,

I am facing the strange issue in which the Pricing of my Azure SQL database is being changed from DTU based pricing model (with Basic 5 DTUs) to vCore based pricing which is affecting the monthly cost. I have to manually change it back to the DTU based model.

No enough information is available in activity logs as well . Can someone guid me about this and why is this changing automatically ?

Thanks in advance

Hi @Nasir Siddiqui

Thank you for sharing the required details.

Based on the private information you provided, this issue appears to be related to billing and support for billing questions. You mentioned that 7 or 8 days ago, the pricing was changed to vCore-based pricing, which affects the cost. If any changes related to compute have occurred, they should be tracked in the Azure Activity Log.

If possible, could you please share the Azure Activity Logs for further analysis?".

If you would like to open a support ticket from your Azure subscription through the Azure Portal to increase the quota limit, we can provide you with the process document.

Please let me know if you need any more information. We are happy to assist.

It is highly unlikely that system would change SLO by itself. Can you please share server name and database name with @Mallaiah Sangi in a private message. I will work with him to figure this out.

Thanks for sharing the details, @Nasir Siddiqui

We looked at the databases and their history.

qa-xxx-database

DB was on Basic tier and renamed as qa-xxx-database-backup on 2025-04-03
New database qa-tcf-database was created with vcore model on same logical server.
SLO changed of new database to Basic on 2025-04-07 (around 06:55 UTC).
Currently both databases exist on same logical server.

dev-xxx-database:

Created on 2025-02-13 as Basic
Recreated on 2025-02-25 as SQLDB_GP_GEN5_2
SLO changed on 2025-03-03 to Basic
Recreated on 2025-03-25 as SQLDB_GP_GEN5_2
Recreated on 2025-03-28 as SQLDB_GP_GEN5_2
SLO changed on 2025-04-07 to Basic

(note I have masked the database name as they might be sensitive names)

So, it doesn't look like system is changing SLO automatically. The database was actually created with the vCore SLO. You have to check with your team about which process is dropping and creating database.

Hi Balmukund,

Thanks for all your help , one last question , is it possible that database can be dropped or recreated with the vCore based SKU using the database user from SQL management studio instead of azure portal ?

As per the activity logs , it seems that database was recreated using the 'sqladmin' user that is the database user on our azure sql database server

Yes, SQL database can be dropped/created using any of 5 methods: Azure Portal, Azure CLI, PowerShell, REST API and T-SQL.
