Modernizing Enterprise Applications with CICS

Mainframe systems power the world's most critical transactions, but keeping them isolated is no longer an option for modern businesses. Transitioning these robust core systems into modern, cloud-connected environments is essential for today's enterprise developers and architects. This text-only course guides you through the fundamental process of modernizing legacy CICS applications. You will understand how CICS processes transactions, read through clear architectural explanations, and learn how to expose core mainframe logic to contemporary web services. By the end of this course, you will know how to bridge the gap between traditional enterprise systems and modern hybrid cloud architectures. What you'll learn: - Understand the foundational architecture of CICS and how it processes high-volume enterprise transactions. - Analyze legacy application structures to identify modernization opportunities. - Configure modern REST APIs to expose legacy mainframe functions to external applications. - Explore hybrid cloud integration patterns to connect CICS with modern cloud platforms. - Apply security and performance best practices for modernized transaction workflows. The course begins with essential mainframe and transaction processing terminology before moving into practical modernization strategies. You will progress from basic definitions to reading and understanding integration patterns and API configurations. This course is designed for beginner developers, system analysts, and IT professionals new to mainframe modernization, with no prior mainframe experience required.
