When you swipe a card or tap your phone, there is a 70% chance a Mainframe is processing that transaction. For banks and payment processors, the Mainframe isn't just a "legacy" system—it is the engine of revenue. Managing these systems requires a balance between zero-downtime stability and the need for modern agility.
The challenge today isn't just maintaining COBOL code; it is managing the complex service layers that connect these ancient giants to modern mobile apps, instant payment rails, and cloud analytics.
1. The Integration Challenge (Hybrid Cloud)
Modern payment systems live in the cloud, but the ledger lives on the Mainframe. The bottleneck is the connection. Successful management requires moving away from file-based transfers (FTP) to Real-time API Integration (using tools like z/OS Connect). This allows your mobile app to "talk" to the Mainframe instantly without rewriting the core logic.
2. Preparing for ISO 20022
The global standard for payments messaging (ISO 20022) is data-rich. Legacy payment systems built on
fixed-width fields (COBOL copybooks) struggle to handle this extra data.
The Strategy: Instead of expanding every database field on the mainframe (high risk),
we implement a "Payment Hub" architecture that handles the rich data validation before it hits the core ledger.
3. Modernizing Operations (DevOps)
You cannot manage 2026 payments with 1990s tools. We help organizations implement modern DevOps pipelines for Mainframes.
- CI/CD for COBOL: Automated testing pipelines that run every time a developer commits code.
- Observability: Moving logs from "green screens" to modern dashboards like Splunk or Elastic for real-time error tracking.
- Risk Mitigation: Decoupling "Read" traffic (Account balance checks) to the cloud to reduce MIPS costs.
