The latest Azure offering, Purview, is a “unified data governance” service to help organisations manage data across their ever expanding environments – including on-premises, IaaS multi-cloud (Azure, AWS etc.) and also SaaS services. According to Microsoft, Azure Purview will offer automated discovery and classification of data, a map of where it all resides and how it relates to each other, easy searching to locate data, and an overview of how data moves across your organisation.

Given the increasing amounts of data we all create and collect, combined with the rising threat of cyber attacks – at a personal, corporate, and national level – this is a welcome introduction.


Azure Purview is (almost) free to try until February 28, 2021 but we can already see an overview of how it will be priced going forward.

First of all, you need to provision the “Data Map” – this is priced based on 2 things…Capacity Units and metadata storage.

Capacity Units

This is a set of resources provisioned in order to keep your Data Map up and running. One Capacity Unit can support “approx. 1 API call per second” and is currently priced at $0.342 per hour.

Metadata storage

This stores the metadata associated with the scanned assets which enables the searching capabilities within Purview. Microsoft talk about this being in a “graph” format – so this appears to be another element of the “Microsoft Graph” being surfaced as part of a product. Pricing is yet to be announced but will be on a per GB basis…I can well imagine many organisations finding themselves with a HUGE amount of this metadata storage!


When it comes to scanning your environment, this is charged at $0.63 per “v-core hour” that you consume whilst actively scanning. Microsoft state there will be no “incremental charges” for connectors to 3rd party datastores.

Almost regardless of cost, I think many organisations will find it hard not to use this service – given the worries, risks, and potential fines that data mismanagement can bring. Microsoft have made another strong move to position themselves as an integral part of the future of business. Even if everyone stopped using Windows and Office tomorrow, Azure Purview (and other new services) would keep Microsoft at the forefront of many an organisation’s mind for years to come.
