Enterprises running mission-critical workloads cannot afford planned outages for maintenance and updates. AIX Zero Planned Downtime (ZPD) capabilities are designed to eliminate this trade-off by enabling system updates while applications remain online.This session provides a deep dive into AIX ZPD technologies, with a focus on AIX Live Kernel Update and Live Library Update. Attendees will learn how these capabilities allow critical fixes and updates to be applied without rebooting systems or disrupting running workloads.Through architectural insights and a live demonstration, we will show how AIX enables continuous availability, reduces operational risk, and simplifies maintenance for always-on enterprise environments. Participants will leave with a clear understanding of where ZPD fits into their AIX strategy and how to adopt it effectively in production environments.
