You have questions. We have answers.

Kyndryl Managed Infrastructure Services help operate IBM Z and IBM i across on-premises, hosted, dedicated and shared models, combining infrastructure management, automation, resilience and operational insight.

Running the estate creates production insight into performance, cost, capacity and operational risk. That context can help identify where to optimize, modernize, integrate or transform workloads.

No. Modernization can improve workloads on the mainframe, integrate them with cloud and AI services, or move selected workloads when business value, risk and economics justify it.
