This architecture describes how to implement an Information Management System (IMS) mainframe application workload on Azure by using Raincode's IMSql. Migrating an IMS database (DB) application to a cloud-native solution is more complex than migrating a relational database application. This article describes how to seamlessly rehost a mainframe IMS workload that has critical IMS features and capabilities to Azure. You don't need to translate or modify your existing application.
