Case Study: Union Bank achieves faster mainframe API delivery with OpenLegacy

Union Bank uses OpenLegacy to integrate mainframe into new digital platform

Union Bank, a top 20 U.S. bank, faced the significant challenge of integrating its mainframe into a new, modern digital platform. This process was hindered by complex middleware and was projected to take months. To overcome this obstacle and leverage its mainframe investments, the bank partnered with vendor OpenLegacy.

Using the OpenLegacy platform, in a short two-week pilot the bank successfully delivered five different use cases, including enabling the mainframe to be a provider and consumer of Kafka events and REST APIs. This resulted in a 10x improvement in time-to-market and significant capital savings. The solution maximized the value of the bank's existing hardware and was so successful that Union Bank decided to standardize on the OpenLegacy platform for all future digital initiatives.
