Part 6/10:

• Transactional Data Pipelines: To power real-time features, they built custom data pipelines called DFS, replacing multiple third-party systems like SQS and RabbitMQ. These pipelines ingest, process, and catalog billions of events efficiently.

• Data Governance & Validation: Given cybersecurity responsibilities, a robust governance framework ensures data integrity, privacy, and compliance. In-house SDKs conduct deep data validation before ingestion.

• AWS-Centric Infrastructure: The entire architecture is built on AWS, employing services such as Glue for cataloging, Delta Lake for storage, and Bedrock for AI workloads. This consolidation reduces complexity and leverages AWS's integrated offerings.
