This pattern shows you how to modernize your business-critical mainframe online printing workloads on the Amazon Web Services (AWS) Cloud by using Micro Focus Enterprise Server as a runtime for a modernized mainframe application and LRS VPSX/MFI (Micro Focus Interface) as a print server. The pattern is based on the replatform mainframe modernization approach. In this approach, you migrate your mainframe online application to Amazon Elastic Compute Cloud (Amazon EC2) and migrate your mainframe database, such as IBM DB2 for z/OS, to Amazon Relational Database Service (Amazon RDS).
