A Governed AWS Lakehouse for Financial Services
Replacing fragmented, manual data operations with automation, quality checks, and governance
The Policy
This financial services provider has helped other institutions grow and protect their businesses for decades. More than 6,000 clients across North America have relied on it to help them grow through a range of lending, marketing, and risk management solutions.
As part of an ambitious new business strategy, the client was looking to connect its data across products and business functions. But that would take a strategy to turn all that data into a modern platform, prove the value of a governed lakehouse, and enable adoption across the organization.
The Fine Print
Data operations had reached the point where manual effort and fragmented systems were actively slowing down growth.
Manual Onboarding and Review. Client onboarding and data review took multiple exchanges, manual checks, and human intervention. All of that added up: too much time to kick off new projects, too much time spent moving information back and forth across systems, and constant correction cycles in between.
Fragmented Data. Part of the problem was that data came from multiple source systems and external parties. Reconciling that amount of information was difficult, made even more so by limited visibility into where information came from, how it changed, and whether it was ready to use.
Quality and Compliance Pressure. That opaque data quality and lineage also made it hard to support risk monitoring, portfolio analytics, and regulatory reporting, which were all important to the client’s operations.
A modernization plan of that magnitude needed its own platform. The architecture would have to support reusable ingestion and consumption patterns, and transitioning from MVP to enterprise-scale use cases. That was a tall order, and a bigger ask than just a new cloud environment or new tools. The client needed a partner that could connect business goals to architecture, automation, governance, and day-to-day operations, and then help make the whole thing real.
The Umbrella
This engagement aligned with four areas of AHEAD’s expertise.
- Data Platform Modernization: Establishing a common lakehouse foundation for bringing together external data and making it usable for analytics and applications.
- Platform & Workload Modernization: Designing reusable ingestion, consumption, and event-driven patterns.
- Secure & Resilient Architectures: Incorporating least-privilege access, encryption, segregated environments, MFA, and centralized logging, so the platform had built-in governance and risk controls.
- Operational Excellence: Automating health checks, data quality rules, and knowledge transfer so the platform could grow and remain supportable over time.
The work unfolded across three phases:
Advise
AHEAD and the client began by defining the modernization path. Together, they established program readiness, inventoried related initiatives and dependencies, and assessed people and process gaps. They also designed the target architecture and selected use cases that would allow them to review the ingestion and consumption patterns and the tools the platform would require.
Why the Groundwork Mattered: AHEAD's strategic approach outlined a data lakehouse operating model for the client. This was what made the client’s platform and modernization ambition real and grounded in shared, governed architecture. Important design, dependency, and risk decisions were addressed before implementation began.
Build
AHEAD and the client then built the data platform MVP across dedicated development, staging, and production environments.
AWS provided the cloud foundation with landing and medallion-layer storage. Amazon S3 events triggered Step Functions workflows that coordinated Lambda validation and health checks. AWS Glue handled profiling and transformation, enrichment, error handling, and notifications. This was rounded out by API Gateway and Kinesis supporting synchronous and streaming patterns, while RDS and Aurora supported dataset and runtime information.
Together, the teams operationalized governance and data quality through Alation, which established access and consumption guardrails. Infrastructure was deployed through Terraform and GitHub as code. And implementation was validated through component and end-to-end integration testing before moving into production with knowledge transfer and a two-week hypercare period.
How It Came to Life: All of this intricate design work meant the client had a working, repeatable set of ingestion, governance, and operational capabilities alongside its lakehouse. Manual data handling became an automated, testable platform that could validate information while it moved and support multiple workloads.
Run
After the platform went live, AHEAD provided post-production hypercare to fine-tune its monitoring capabilities, track data health, and support knowledge transfer.
How It Kept Delivering: The platform was transitioned to internal teams for adoption. The MVP was now a living capability that could keep improving over time.
Fully Covered
Data started doing the waiting, checking, and routing all on its own.
By the Numbers. Average file review time decreased by 99.7%, from four days to 20 minutes. Meanwhile, average client review time decreased by 58.3%, taking five days where it used to take twelve. The business case also estimated $1 million in annual benefits tied to labor costs and increased tracking fee revenue.
Quality and Consistency. Automated ingestion, validation, and data health checks reduced the need for manual review as a first line of defense. Governance and catalog capabilities gave the client a structured way to manage data quality, access, and accountability.
A Foundation for Scale. The production MVP established reusable patterns for data ingestion and consumption, opening up the gates to additional risk, compliance, and marketing use cases.
What’s Next
With a governed AWS data platform in place, the client is well-positioned to keep growing beyond the initial MVP. For financial services, data modernization should be treated as an operating model, not a storage decision. AHEAD brings strategy, architecture, engineering, and governance together in one conversation, so organizations can move quickly from scattered data and noble ambitions to real platforms that are actively delivering real value.
