Executive Summary

ANALYST: COI RESEARCH

Strategic shift from monolithic on-premise data centers to a federated public cloud data mesh, decentralizing ownership to domain teams while enforcing automated governance.

rate_review Analyst Verdict

"The industry standard for cloud-native banking architecture. While technically superior, it requires a massive cultural shift in engineering practices that smaller banks may struggle to replicate."

warning The Challenge

The bank faced significant friction with its legacy monolithic data lakes, where a central team became a bottleneck for data ingestion and quality management. With over 6,000 applications and petabytes of data, the on-premise infrastructure struggled to support the velocity required for modern analytics and AI development. Furthermore, the reliance on static infrastructure created potential security vulnerabilities (drift) and made it difficult to enforce consistent governance policies across the global estate without stifling innovation.

psychology The Solution

The institution adopted a Data Mesh architecture deployed on AWS, which fundamentally decentralized data ownership to domain-specific teams while enforcing federated governance. A key technical innovation was the implementation of an 'immutable infrastructure' strategy, where the entire environment is automatically 'repaved' (wiped and recreated) on a weekly basis using Infrastructure-as-Code (IaC). This approach eliminates configuration drift and security vulnerabilities while ensuring that data products are accessible via secure, documented APIs for cross-line-of-business consumption.
