Learn how to optimize workload management across multiple clusters through a real-world case study of OpenShift CI infrastructure evolution in this 13-minute conference talk from DevConf.CZ 2025. Discover the strategic transition from managing a few large clusters to operating an agile network of smaller clusters, and explore the dynamic strategies developed for handling job reshuffling during outages, maintenance, and other operational disruptions. Examine key factors that enhance scalability in multi-cluster environments, including execution history analysis, cluster capability assessment, and system architecture considerations. Gain practical insights into building resilient distributed systems that can adapt to changing operational requirements while maintaining optimal performance across your infrastructure landscape.
