The pattern is based on the replatform mainframe modernization approach. Mainframe applications are migrated by AWS Mainframe Modernization on Amazon Elastic Compute Cloud (Amazon EC2). Mainframe output-management workloads are migrated to Amazon EC2, and a mainframe database, such as IBM Db2 for z/OS, is migrated to Amazon Relational Database Service (Amazon RDS). The LRS Directory Integration Server (LRS/DIS) works with AWS Directory Service for Microsoft Active Directory for output-management workflow authentication and authorization.
