Integration architectures between mainframe and AWS for coexistence

This article discusses various integration architectures and patterns for coexistence between mainframe systems and AWS during mainframe modernization initiatives.

Specifically, the article covers:

• Three main types of integrations: application-to-application, data-to-data, and application-to-data
• Application-to-application integration patterns: point-to-point using JCA connectors, API-based integration, and message oriented/event driven integration
• Data-to-data integration patterns: near real-time data transfer, file-based transfers, ETL-based transfers, and archived data transfer
• Application-to-data integration patterns: single copy of data and dual writes
• Conclusion: No one-size-fits-all solution, careful consideration required based on factors like throughput, performance, and location of primary data
