Azure Purview Costs in Public Preview explained

by Feb 2, 2021

Why are you potentially charged for Azure Purview during the public preview?

Since I published my post that Azure Purview started billing as of January 21th, I got a lot of questions how billing was working.

UPDATE 27th of February: We are extending the Azure Purview offer to provision 4 Capacity Units of the Data Map for free till May 31, 2021! Charging will start on June 1, 2021.

UPDATE 1st of June: Azure Purview has started billing

UPDATE 18th of August: All new Azure Purview account created after August 18th, 2021 will have a new pricing model, please check the details in my article here.

As a small recap:

Azure Purview Data Map

Capacity Unit €0.289 per 1 Capacity Unit Hour
Provisioned API throughput. 1 capacity unit = 1 API/sec
Includes 4 capacity units for free until May 31, 2021.
Metadata Storage Free

When you have created your Azure Purview with 4 capacity Units it looks like Azure Purview is free, but that’s not entirely true. Below is an overview of my costs of Azure Purview (4 capacity units) from the last 10 days of January.

Azure Purview Costs

My costs are rising every day, to save some money I changed my weekly scans to manual scans. But that’s only a small amount of the total.

Looking into detail you will see that you are charged for around 25 a day, what will be 750 a Month.

When we do the calculation from the table in the beginning of this Article.  We have 4 Capacity units, each unit cost €0.289, 24 hrs a day. 4x€0.289X24 =€27,74. So that means that we are charged for our 4 Capacity units, which should be for free until February 28, 2021. Strange

Azure Purview Costs Detail


After I had some contact with the Product Team I got the following answer/explanation back:

During Preview, you can pick from two sizes for the Data Map – 4 Capacity Units for trials/dev or 16 Capacity units for actual usage.

Till may31,2021, use of the 4 CU Data Map and 16 vCore-hour is as a free offer.

This offer is only available for customers with the following subscription offer types:

  • Pay-As-You-Go (MS-AZR-0003P),
  • Microsoft Azure Enterprise (MS-AZR-0017P)
  • Microsoft Azure Plan (MS-AZR-0017G)
  • Azure in CSP (MS-AZR-0145P)
  • Enterprise Dev/Test (MS-AZR-0148P)

Free quantities are applied at the enrollment level for enterprise customers. Free quantities are applied at the subscription level for pay-as-you-go customers.

For comparison, customers can get started with Azure Purview for as low as $18k a year, where as typical boxed-software Data Catalogs typically start at $25-50k for software and then require VM costs + devops maintenance costs and can’t be scaled up/down for scanning. The good news is that development to auto-scale, smaller starting size and smaller increments of the dedicated capacity of the Data Map is in progress so by GA, you’ll be able to try Azure Purview accounts for a fraction of the current cost.

Unfortunately, MSDN subscriptions and free trial subscriptions don’t get the free offer benefit, hence you’re seeing this show up. I recommend trying Azure Purview in one of your Azure subscriptions that’s eligible for the free offer.
