How Volkswagen Autoeuropa built a data solution with a robust governance framework, simplifying access to quality data using Amazon DataZone

This is a joint post co-authored with Martin Mikoleizig from Volkswagen Autoeuropa.

This second post of a two-part series that details how Volkswagen Autoeuropa, a Volkswagen Group plant, together with AWS, built a data solution with a robust governance framework using Amazon DataZone to become a data-driven factory. Part 1 of this series focused on the customer challenges, overall solution architecture and solution features, and how they helped Volkswagen Autoeuropa overcome their challenges. This post dives into the technical details, highlighting the robust data governance framework that enables ease of access to quality data using Amazon DataZone.

At Amazon, we work backward, a systematic way to vet ideas and create new products. The key tenet of this approach is to start by defining the customer experience, then iteratively work backward from that point until the team achieves clarity of thought around what to build. The first section of this post discusses how we aligned the technical design of the data solution with the data strategy of Volkswagen Autoeuropa. Next, we detail the governance guardrails of the Volkswagen Autoeuropa data solution. Finally, we highlight the key business outcomes.

Aligning the solution with the data strategy

At an early stage of the project, the Volkswagen Autoeuropa and AWS team identified that a data mesh architecture for the data solution aligns with the Volkswagen Autoeuropa’s vision of becoming a data-driven factory. With this in mind, the team implemented the following steps:

• Define data domains – In a workshop, the team identified the data landscape and its distribution in Volkswagen Autoeuropa. Next, the team grouped the data assets of the organization along the lines of business and defined the data domains. Because Volkswagen Autoeuropa is at an early stage of their data mesh journey, defining data domains along the lines of business is the recommended approach. As the data solution evolves, Volkswagen Autoeuropa might consider other criteria such as business subdomains to define data domains. The team defined more than five data domains, such as production, quality, logistics, planning, and finance.
• Identify pioneer cases – The team identified the pioneer use cases that onboard the data solution first, to validate its business value. The team identified two use cases. The first use case helps predict test results during the car assembly process. The second use case enables the creation of reports containing shop floor key metrics for different management levels. The following criteria were considered to identify these use cases:
  • Use cases that deliver measurable business value for Volkswagen Autoeuropa.
  • Use cases with high AWS maturity.
  • Use cases whose requirements can be met with the first release version of the data solution.
• Onboard key data products – The team identified the key data products that enabled these two use cases and aligned to onboard them into the data solution. These data products belonged to data domains such as production, finance, and logistics. In addition, the team aligned on business metadata attributes that would help with data discovery. The data products are classified as either source-based data or consumer-based data. Source-based data is the unaltered, raw data that is generated from source systems (for example, quality data, safety data) and is useful for other business use cases. Consumer-based data is the aggregated and transformed data from source systems. Reuse of consumer-based data saves cost in extract, transform, and load (ETL) implementation and system maintenance.

In addition to the preceding steps, the team established a data quality framework to improve the quality of the data product registered in the data solution. The following table shows the mapping of the data mesh-based solution components to Amazon DataZone and AWS Glue features. The table also provides generic examples of the components in the automotive industry.

Data Solution Components	AWS Service Features	Generic Examples
Data domains	Amazon DataZone projects and Amazon DataZone domain units	Production, logistics
Use cases	Amazon DataZone projects	Smart manufacturing, predictive maintenance
Data products	Amazon DataZone assets	Sales data, sensor data
Business metadata	Amazon DataZone glossaries and metadata forms	Data product owner information, data refresh frequency
Data quality framework	AWS Glue Data Quality	A quality score of 92%

Empowering teams with a governance framework

This section discusses the governance framework that was put in place to empower the teams at Volkswagen Autoeuropa by enhancing their analytics journey. It highlights the guardrails that enable ease of access to quality data.

Business metadata

Business metadata helps users understand the context of the data, which can lead to increased trust in the data. Moreover, establishing a common set of attributes of the data products promotes a consistent experience for the users. In addition to the business context, at Volkswagen Autoeuropa, the metadata includes information related to data classification and if the data contains personally identifiable information (PII). The data solution uses Amazon DataZone glossaries and metadata forms to provide business context to their data. Apart from the previous benefits, using the appropriate keywords in Amazon DataZone glossary terms and metadata forms can help with the search and filtering capability of data products in the Amazon DataZone data portal.

Data quality framework

The data quality framework is a comprehensive solution designed to streamline the process of data quality checks and publishing a quality score. It uses AWS Glue Data Quality to generate recommendation rulesets, run orchestrated jobs, store results, and send notifications. This framework can be seamlessly integrated into an AWS Glue job, providing a quality score for data pipeline jobs. The quality score of a data product is published in the Amazon DataZone data portal for consumers to evaluate. The key components of the solution are as follows:

• Recommendation ruleset generation – The framework generates tailored rulesets based on metadata from the AWS Glue Data Catalog table, providing relevant and comprehensive quality checks.
• Orchestrated job execution – Jobs are run in AWS Step Functions to perform data quality checks using the generated rulesets against data sources, evaluating data quality based on defined rules and criteria.
• Result storage and notification – Results, including quality scores, quality status, and rulesets checked, are stored in an Amazon Simple Storage Service (Amazon S3) bucket, maintaining a historical record. End-users receive notifications with relevant details.
• Data quality score publishing – The quality scores are published in the Amazon DataZone data portal, enabling consumers to access and evaluate data quality.
• Subscription and quality score requirements – Consumers can subscribe to data sources or targets based on their desired quality score thresholds, making sure they receive data that meets their specific needs and standards.
• Integration and extensibility – The framework is designed for seamless integration into existing AWS Glue jobs or data pipelines and provides a flexible and extensible architecture for customization and enhancement.

Federated governance

Federated governance empowers producer and consumer teams to operate independently while adhering to a central governance model. For the data solution at Volkswagen Autoeuropa, this meant a centralized team defined the governance guardrails and decentralized data teams employed those guardrails. The following are a few examples of how the team established federated governance in Volkswagen Autoeuropa:

• Management of Amazon DataZone glossaries and metadata forms – In this mechanism, the Volkswagen Autoeuropa IT team defined the Amazon DataZone glossaries and metadata forms in a central manner. The data teams used them to publish the data assets in the Amazon DataZone. This provides consistency of business metadata across the organization. The following figure explains the process.
  The workflow in the Amazon DataZone data portal consists of the following steps:

1. 1. The data solution administrator belonging to the Volkswagen Autoeuropa IT team aligns with stakeholders such as data producers, data consumers, and source system owners, and maintains the business metadata using the Amazon DataZone glossaries and metadata forms.
   2. The producer project teams use the Amazon DataZone glossary terms and fill the Amazon DataZone metadata forms to enrich the inventory assets.
   3. After the business metadata is populated, the team publishes the assets in the Amazon DataZone data portal.

• Management of Amazon DataZone project membership – In this scenario, the management of Amazon DataZone project membership is delegated to a designated administrator of the project. The following figure explains the process.
  The workflow consists of the following steps:

1. 1. The data solution administrator belonging to the Volkswagen Autoeuropa IT team provisions the Amazon DataZone project and environment using automation. The data solution administrator is the owner of the project.
   2. The data solution administrator delegates the management of the Amazon DataZone project membership to a designated administrator by assigning the owner role.
   3. The Amazon DataZone project administrator assigns the contributor role to eligible users.
   4. The users access the Amazon DataZone project and its assets from the Amazon DataZone data portal.

Authentication and authorization

The Amazon DataZone portal supports two types of authorizations: AWS Identity and Access Management (IAM) roles and AWS IAM Identity Center users. The data solution supports both of these authorization methods. The choice of authentication mechanism is a function of the type of authorization used for Amazon DataZone.

For IAM role authorization, an IAM role is created for each user, incorporating a prefix. Each data solution user role has a permission to list the Amazon DataZone domains (datazone:ListDomains) and to get the data portal login URL (datazone:GetIamPortalLoginUrl) in the Amazon DataZone AWS account. For reasons that are out of scope for this post, there could only be three SAML federated roles in an AWS account in the customer environment. As such, the team didn’t have a dedicated SAML federated role for each Amazon DataZone user. The data solution user role implemented a trust policy allowing the user’s AWS Security Token Service (AWS STS) federated user session principal Amazon Resource Name (ARN). If you don’t have limitations on the number of SAML federated roles per AWS account, you can make all data solution user roles SAML federated roles and update the trust policy accordingly.

For IAM Identity Center authorization, the configuration is done either at the AWS Organizations level or AWS account level in IAM Identity Center. Because there are currently no APIs available for identity source configuration in IAM Identity Center, the team followed the appropriate instructions to configure the identity source on the AWS Management Console.

After the chosen authorization option is activated, Amazon DataZone administrators grant the IAM principals (IAM role or IAM Identity Center user) access to the Amazon DataZone portal. For more details, refer to Manage users in the Amazon DataZone console.

Business outcomes

Volkswagen Autoeuropa and AWS established an iterative mechanism to enable the continuous growth of the data solution. This iterative improvement is expressed as a flywheel as shown in the following figure.

The outcome of each component of the flywheel powers the next component, creating a virtuous cycle. The data solution flywheel consists of five components:

1. Data solution growth – The primary focus of the flywheel is to accelerate the growth of the data solution. This growth is measured by metrics such as number of data products, number of use cases onboarded into the solution, and number of users.
2. Enhancing user experience – This component focuses on enhancing the user experience of the data solution. One way to measure the user experience is through user feedback surveys.
3. Data solution use cases – Improved, positive user experience with the data solution contributes to the increased number of use cases that want to onboard the data solution.
4. Data producers and consumers – As the number of use cases increases, so does the number of data producers and consumers. Data producers make data available to power the use cases. Data consumers use the data to drive the use cases.
5. Selection of data products – After data producers onboard the data solution, they publish the assets in the Amazon DataZone data portal. This leads to a larger selection of data products. This, in turn, creates a positive experience for the data solution users.

In addition to the previous components, the positive user experience is reinforced by improving governance guardrails, increasing number of reusable assets, and maximizing operational excellence.

As of writing this post, Volkswagen Autoeuropa reduced the time to discover data from days to minutes using the data solution. This led to approximately 384 times improvement in data discovery time. Data access took several weeks before the Volkswagen Autoeuropa and AWS collaboration. With the help of the data solution powered by Amazon DataZone, the data access time was reduced to minutes. Overall, the data solution resulted in regaining between 48 hours and weeks of customer productivity over the course of a month.

The data solution powered by Amazon DataZone is driving measurable business impact for Volkswagen Autoeuropa. It enables Volkswagen Autoeuropa to deliver digital use cases faster, with less effort, and a higher overall quality. Volkswagen Autoeuropa believes that Amazon DataZone will be key in their journey to become a data-driven factory and to leverage AI.
