Global Bank Migrates 40-Year-Old COBOL Systems to AWS
How a leading financial institution migrated critical payment processing systems to AWS with zero downtime and a fraction of the originally estimated timeline.
Challenge:
Legacy COBOL systems handling $2B daily transactions needed modernization without any service interruption.
Results:
- Up to 60% cost reduction
- Zero downtime migration
- 18-month timeline vs 5-year manual estimate
SaaS Platform Decomposes Java EE Monolith Into Microservices in 10 Weeks
AI-powered service boundary detection mapped 800,000 lines of Java EE code into 14 bounded microservices — with pre-flight previews and parallel-run validation at every step.
Challenge:
A B2B SaaS company had outgrown its Java EE monolith — deployment risk was high, teams were blocked, and no consulting firm could quote under 18 months. They needed a deterministic path to microservices without a full rewrite.
Results:
- 14 microservices extracted from a single monolith
- Pre-flight preview caught 23 hidden dependencies
- Full rollback available throughout — zero forced cutovers
Federal Agency Migrates RACF to Azure Active Directory in 90 Days
A US federal agency migrated 18,000 RACF user accounts and 4,200 resource profiles to Azure AD with full privilege mapping validation and zero unauthorized access events.
Challenge:
18,000 active RACF user accounts with complex SPECIAL and OPERATIONS privilege hierarchies needed to be migrated to Azure AD while maintaining existing access controls and generating a defensible audit trail.
Results:
- 18,000 users migrated in 90 days
- Zero unauthorized access events
- FedRAMP-ready audit trail generated
Regional Insurance Group Migrates 12TB DB2 Warehouse to Snowflake
AI-powered schema mapping and CDC-based zero-downtime migration moved 12TB of actuarial and claims data from DB2 to Snowflake in under six weeks.
Challenge:
12TB DB2 data warehouse supporting actuarial models and claims processing needed migration to Snowflake for real-time analytics, with no tolerance for data loss.
Results:
- 12TB migrated in 6 weeks
- Zero data loss — 100% quality score
- Up to 70% query performance improvement
Healthcare Provider Achieves SOC 2 Compliance in 4 Months
Automated security controls reduced audit prep from 6 months to 4 months while enabling continuous compliance monitoring across three cloud environments.
Challenge:
Multi-cloud environment needed SOC 2 Type II certification for new customer contracts.
Results:
- 4-month compliance timeline
- Up to 90% reduction in manual effort
- Continuous monitoring enabled
E-Commerce Company Saves $2.4M in Annual Cloud Costs
Real-time monitoring and automated optimization cut cloud spending by up to 45% across five AWS accounts without any performance impact.
Challenge:
Uncontrolled cloud spending across 5 AWS accounts with no visibility or governance framework.
Results:
- Up to $2.4M annual savings
- Up to 45% cost reduction
- Zero performance degradation
Telco Validates 6,000 Regression Tests Before Mainframe Cutover
TN3270 session recording and AI-powered field mapping generated a 6,000-test regression suite that caught 47 business logic defects before the production cutover.
Challenge:
A major telco needed to validate that migrated billing and provisioning systems matched mainframe behavior exactly, across millions of daily transactions, before the point-of-no-return cutover.
Results:
- 6,000 regression tests auto-generated
- 47 critical defects caught pre-cutover
- Load tested at 10× peak traffic capacity
