With TBC's IBM Mainframe Management, your organization gains: - IT teams: Specialized mainframe and IBM i expertise without additional hiring, proactive monitoring and maintenance, and a clear, practical modernization roadmap. - Executives: End-to-end support, predictable costs, reduced risk of downtime to mission-critical systems, and modernized applications ready to integrate with new technologies. ### Protect your core systems and empower your team to innovate today.

TBC handles OS and PTF updates, high availability and Active/Active environments, Db2 for i performance, and monitoring to keep your environment running at its best. We also integrate IBM i with cloud, ERP, and SaaS platforms through APIs. ![Target](https://www.tbconsulting.com/hubfs/Website%20Redo/Icons/Target.svg) Stability Assessment A fixed-scope, evidence-based review of your mainframe or IBM i environment. TBC traces instability to its root cause across architecture, Db2, applications, and high availability. We validate the findings through testing and deliver a prioritized roadmap you own, with quick wins first. Unlike assessment-only providers, our team can then implement the fixes. ![Presentation](https://www.tbconsulting.com/hubfs/Website%20Redo/Icons/Presentation.svg) Mainframe Modernization Modernize at the pace your business needs, without a risky rip-and-replace. TBC refactors COBOL and RPG applications, replaces green-screen interfaces with web and mobile front ends, and opens core systems to cloud and analytics through APIs. When moving workloads off-platform makes sense, we plan and execute phased migrations that protect uptime and data integrity. #### Are you ready to strengthen and modernize your mainframe and iSeries environments?
