Case Study: Atruvia achieves efficient, low-risk core banking modernization with IBM zSystems and Java/IMS

Efficient, low-risk modernization of core banking applications

Atruvia AG, the digitization partner for Germany’s cooperative banks, faced the challenge of modernizing its core banking applications while preserving the security, reliability, and performance of its IBM zSystems-based IMS/COBOL environment. With aging COBOL skills and growing demand for new omnichannel services, Atruvia chose IBM to help reduce modernization risk and support faster development, using Java alongside its existing core banking stack.

IBM implemented a Java-in-IMS approach on IBM zSystems, enabling Atruvia to refactor applications incrementally instead of doing a risky “lift and shift.” The results were substantial: Atruvia Java-enabled about 85% of its core banking IMS transactions, processes around 400 million Java transactions per day, and achieved 3x faster performance for some colocated Java workloads. IBM’s solution also simplified batch processing, reduced architectural complexity, and improved developer productivity and time-to-market.
