How to Scan an Arc-Enabled SQL Server in Microsoft Purview

Understanding the Importance of Scanning an Arc-Enabled SQL Server in Purview

In today’s data-driven world, businesses increasingly rely on complex data ecosystems that span across on-premises, cloud, and hybrid environments. Managing this diverse data landscape has led to the rise of tools like Microsoft Purview, which provide seamless data governance, cataloging, and security management. One of the core features of Purview is its ability to scan and manage metadata across diverse data sources.

When dealing with SQL Server, which is one of the most widely used database platforms globally, organizations often find themselves managing large amounts of sensitive data, especially in hybrid or multi-cloud environments. Microsoft's Azure Arc extends Azure services to on-premises, multi-cloud, and edge environments, bridging the gap between on-premises systems and the cloud. This means that data and services running in environments outside of Azure can still be managed as part of the Azure ecosystem.

When an organization enables Azure Arc on their SQL Server instances, it allows them to bring their on-premises or multi-cloud data into the Azure ecosystem, enabling enhanced governance capabilities with Purview. But to fully unlock the power of Purview's data governance, compliance, and cataloging features, businesses need to scan their Arc-enabled SQL Server instances.

So why is scanning an Arc-enabled SQL Server so crucial?

1. Data Discovery and Metadata Management

Purview provides powerful data discovery capabilities. Scanning your Arc-enabled SQL Server with Purview enables the automatic cataloging of metadata associated with all the datasets within your server. By capturing metadata from across the database, such as table schemas, relationships, and column-level details, Purview helps build a unified catalog of data assets. This, in turn, helps organizations to better understand what data they have, how it is structured, and where it resides, making it easier to search, classify, and manage.

2. Compliance and Security

Governance and compliance are more important than ever. For organizations in regulated industries, scanning the Arc-enabled SQL Server ensures that sensitive data, such as Personally Identifiable Information (PII) or financial records, is correctly classified. Purview’s scanning capabilities can automatically identify and label sensitive data, making it easier to enforce data privacy regulations like GDPR, HIPAA, and others.

3. Optimized Data Integration and Analysis

The metadata captured through scanning in Purview is not just useful for compliance and governance, but also for analytics. By mapping out the structure of your SQL Server environment, data scientists, analysts, and other stakeholders can better understand how data flows across systems, and how to integrate or analyze it more effectively.

With Purview’s scanning features, businesses can create a comprehensive data catalog that integrates not only data from SQL Server but also from other data sources, creating a holistic view of the entire data ecosystem.

4. Centralized Data Management Across Hybrid Environments

As more businesses adopt hybrid cloud environments, managing data across on-premises servers, Azure, and other clouds becomes more complicated. Azure Arc-enabled SQL Server allows organizations to treat their on-premises or multi-cloud resources as part of their Azure environment. By scanning these SQL Server instances with Purview, organizations can centralize their metadata management and governance in one platform, regardless of where the data resides.

5. Efficient Data Lineage and Impact Analysis

One of Purview’s standout features is its data lineage capability. By scanning SQL Server environments, organizations can visualize the movement of data across the system, track its transformations, and analyze how changes in one part of the data pipeline can affect other systems downstream. This helps teams trace and resolve issues faster, improving overall system reliability and operational efficiency.

Getting Started with Scanning Arc-Enabled SQL Server in Purview

To take full advantage of the benefits mentioned above, the first step is to ensure that your Arc-enabled SQL Server is properly configured and connected to Microsoft Purview. This process can seem a bit daunting at first, but once it is set up, the scanning process is straightforward and incredibly valuable.

The first step involves configuring Azure Arc on your SQL Server instances. This typically involves registering your on-premises or multi-cloud SQL Server with Azure Arc, allowing it to be recognized as part of your Azure resources. Once the server is Arc-enabled, you can begin the process of scanning the server using Microsoft Purview.

Now that you understand the importance of scanning Arc-enabled SQL Servers in Purview, let’s dive into the technical steps required to complete this process effectively.

How to Scan an Arc-Enabled SQL Server in Purview

Scanning an Arc-enabled SQL Server in Purview can be broken down into a few simple yet critical steps. This section will guide you through the process and provide best practices to ensure that your scanning is successful and yields the most accurate metadata.

Step 1: Set Up Microsoft Purview

Before scanning your Arc-enabled SQL Server, ensure that Microsoft Purview is set up and configured. You need to have an active Purview account and the appropriate permissions to manage scans. You should have at least Data Curator or Administrator access to configure scans and create scan rules.

Create a Microsoft Purview Account if you haven’t already done so.

Link your Azure subscription to your Purview account to ensure that Purview has access to your Azure resources.

Grant necessary permissions to the Purview account and users to access and scan resources.

Step 2: Register the Arc-Enabled SQL Server as a Data Source

Once Purview is set up, the next step is to register your Arc-enabled SQL Server instance as a data source within the Purview catalog. This allows Purview to recognize the SQL Server instance as a source of metadata.

Navigate to the Microsoft Purview portal.

Go to the "Data Sources" tab and click on "Register." Select "SQL Server" as the type of resource you want to register.

Provide the necessary connection details, such as the server name, authentication credentials, and any additional configuration details specific to the Arc-enabled SQL Server environment.

Confirm the registration and ensure that the connection is successfully established.

Step 3: Configure the Scan

Once the SQL Server is registered, you need to set up the scanning configuration. Scanning is where you specify what kind of metadata Purview should gather, how often the scan should run, and what data should be included or excluded from the scan.

Create a scan by going to the "Scan" section of the Purview portal.

Select the registered Arc-enabled SQL Server from the list of available data sources.

Define scan parameters, such as:

Scan type (full scan or incremental)

Scheduled scan frequency (hourly, daily, weekly, etc.)

Specific databases or tables to include or exclude from the scan

Data classification settings, such as identifying sensitive data.

Save the scan configuration and ensure it is set to run automatically at the scheduled time.

Step 4: Review Scan Results

After configuring and running the scan, you can view the results in the Purview portal. Purview will show you the metadata collected from the Arc-enabled SQL Server, which may include tables, views, columns, and relationships. Additionally, you can view the data classification information, such as which columns contain PII or other sensitive data.

Review metadata insights and validate the data structure to ensure accuracy.

Check for any issues or warnings in the scan results, such as missing data or connection problems.

Monitor compliance by verifying if sensitive data was properly classified and tagged.
