Azure Postgres Flexible Server Cost increase without any plan changes

Question

I'm utilizing Azure Database for PostgreSQL under the Flexible Server - General Purpose Plan with D8ds_v5 / D8ads_v5 configuration, boasting 8 vCores.

After examining my expenditure through cost management tools, I've identified a possible billing discrepancy. Despite being subscribed to the D8ds_v5 plan, which guarantees 8 vCores, the billing report indicates a charge for only 1 vCore with a higher cost.

Could you please provide an explanation for this inconsistency, as I haven't made any alterations to my plan?

Thanks.

Answer 1

Try to verify if the billing period matches your subscription period and check for any pro-rated charges. Another factor could be inaccuracies in billing metrics reporting due to delays or errors.

As you mentioned that you did some investigations, try also to ompare the usage metrics in the Azure portal with the billing report to identify any discrepancies.

My concerns are the following :

• Reserved instances might also be a cause, as they are billed differently, and any usage beyond the reserved amount incurs on-demand charges.
• Resource misallocation or incorrect reporting can also occur. In this case, the resources billed align with those provisioned, and you will have to check the configurations in the Azure portal to confirm that the D8ds_v5 configuration is still in use.

Try to contact the support team :

• Go to the Azure portal.
• Navigate to Help + Support > New support request.
• Select the relevant subscription and fill in the details, explaining the problem.
