AWS Card Application



The AWS Mainframe Modernization team published an IBM mainframe application as open source.

One Application, Many Clouds

We migrated AWS Card to 9 different clouds in 24 hours. You can download the topology grid to access live links to each of the deployed applications.

In addition to AWS Mainframe Modernization, Heirloom supports many other mainframe migration approaches, including Microsoft Mainframe Modernization, Oracle Mainframe Modernization, and Google Mainframe Modernization.
