Financial Services Data Platform Modernization

18 months45 professionals$8.2M budgetCompleted December 2024

Executive Summary

A major financial institution faced critical challenges with their legacy data infrastructure, limiting real-time analytics capabilities and struggling to meet evolving regulatory requirements. We architected and implemented a hybrid cloud data platform that reduced processing time by 85% while saving $4.2M annually in operational costs.

The Challenge

Legacy infrastructure built over 20 years was reaching critical limitations

Key Issues

  • Batch processing windows exceeded 8 hours, missing SLA requirements
  • Regulatory reports took 3 days to generate, risking compliance
  • Data silos across 47 different systems prevented unified analytics
  • Maintenance costs increasing 30% year-over-year
  • Unable to support real-time fraud detection requirements

Business Impact: Risk of regulatory penalties and loss of competitive advantage

The Solution

Hybrid cloud architecture with event-driven processing and automated governance

Phase 1: Assessment & Design

Duration: 3 months

  • Catalogued 2,000+ data assets across all systems
  • Identified critical path dependencies
  • Designed target state architecture
  • Built business case with ROI projections

Phase 2: Foundation

Duration: 6 months

  • Established cloud data lake on AWS
  • Implemented Apache Kafka for event streaming
  • Built data ingestion framework
  • Created automated data quality monitoring

Phase 3: Migration

Duration: 6 months

  • Migrated 500TB of historical data
  • Rebuilt 200+ critical data pipelines
  • Implemented real-time processing for fraud detection
  • Established disaster recovery procedures

Phase 4: Optimization

Duration: 3 months

  • Fine-tuned performance bottlenecks
  • Implemented cost optimization strategies
  • Established DataOps practices
  • Completed knowledge transfer to client team
