Mainframe systems have been the backbone of enterprise computing for decades, renowned for their reliability, performance, and security. However, the evolving business landscape demands agility, scalability, and cost-effectiveness, prompting organizations to explore cloud-based solutions. Major technology companies, including cloud providers and system integrators, have invested heavily in mainframe migration practices, recognizing the significance of this transformation.

Mainframes and cloud computing each have their strengths and specific use cases. It’s not fair to generalize either, and in practice, a hybrid approach is common. This post will explore a practical solution for mainframe workload migration using a hybrid pattern, where certain workloads move to the cloud while still interacting with on-premises applications and data sources.
