About the Client
Our client, a U.S. community bank, was still running 1990s-era mainframes. They faced escalating maintenance costs and limited disaster recovery. Processing was nightly and batch-only. Regulatory pressure was growing. They couldn’t deliver real-time digital banking.
The Challenges
- $2.3M annual mainframe maintenance
- 3-hour daily batch windows; no real-time services
- FDIC examination findings on outdated systems
- Limited disaster recovery and operational visibility
Our AI-Powered Solution
- AI-driven dependency mapping and risk assessment Machine learning mapped applications, data flows, dependencies, flagged blockers, and prioritized cutover with quantified risk scores.
- Automated COBOL-to-Java conversion Automated COBOL-to-Java transpilation preserved business logic, generated unit tests, and enabled cloud-native CI/CD deployment practices.
- Zero-downtime migration strategy Blue-green environments with progressive traffic shifting, health checks, and rollback guards ensured uninterrupted customer services during cutovers.
- Real-time data synchronization Change Data Capture streamed updates with exactly-once semantics, keeping ledgers, payments, and customer profiles synchronized until cutover.
- Comprehensive security hardening Implemented least-privilege IAM, HSM-based key management, segmentation, secrets vaulting, and policy-as-code with continuous scanning and patching SLAs.
- 24×7 monitoring and support Follow-the-sun SRE and NOC coverage provided observability, alerting, on-call response, runbooks, and post-cutover stabilization SLAs.
