Cross-Domain Contracts in Data Engineering on AWS

Introduction

Cross-Domain Contracts are crucial in the context of data engineering, especially in a decentralized approach like Data Mesh. They define the agreements between different domains regarding data exchange, ensuring data availability, quality, and security.

Key Concepts

• Domain: Represents a specific area of responsibility or expertise within the organization.
• Contract: A formal agreement detailing expectations and obligations regarding data.
• Data Product: A product offering that provides data in a consumable format for downstream systems.
• Interoperability: The ability of different systems or domains to work together seamlessly.

Step-by-Step Process

1. Identify the domains involved in data sharing.
2. Define the data products each domain will offer.
3. Establish the contracts detailing data availability, format, and quality metrics.
4. Implement data access mechanisms (e.g., APIs, data lakes).
5. Regularly review and update contracts based on evolving requirements.

Best Practices

• Maintain clear documentation of all contracts.
• Foster open communication between domains.
• Utilize automated testing for data products to ensure quality.
• Regularly audit data access and usage to ensure compliance.
