Dutch Bank Modernizes Payments with ACI and IBM

This case study details the modernization of payment systems at a leading Dutch bank through the implementation of ACI’s BASE24-eps on the IBM Z infrastructure. The bank faced challenges including skills gaps in maintaining its previous HP NonStop Kernel (HPNSK) environment and the need for a compliant, future-proof infrastructure. The solution involved centralizing all retail and card payments on the BASE24-eps platform, which is designed to handle a high volume of transactions efficiently. The architecture includes a fault-tolerant design and ensures 99.999% availability over five years. The results demonstrate improved operational resilience, scalability for future growth, and enhanced governance and regulatory alignment. The partnership between ACI and IBM has been ongoing for over 40 years, focusing on continuous innovation in the bank's payments environment. Future plans include further upgrades to ensure compliance with evolving banking standards and customer expectations.
