Case Study: Leading Credit Card Provider achieves 75% faster consumer website development with OpenLegacy

Leading credit card provider develops consumer website 75% faster with OpenLegacy

Leading Credit Card Provider, a major issuer of credit cards and payment services, needed to modernize its consumer website and add new functionality to stay competitive. Built on IBM zSeries back-end systems, the site had become too slow to extend, with each new service taking about a month to expose and making the planned upgrade feel impractical. OpenLegacy’s zSuite was used to simplify integration without requiring the team to learn new web technologies.

OpenLegacy implemented automated integration of zSeries screens and transactions into web services and REST APIs, avoiding heavy middleware and letting the existing mainframe team handle development. As a result, development time dropped from weeks or months to a few hours per process, and the overall project was estimated to shrink from two years to six months, a 75% reduction. OpenLegacy also helped reduce total cost of ownership by about 75% while improving site functionality and customer experience.
