After migrating 142 production batch workloads from Kubernetes 1.31 CronJobs to Argo Workflows 3.5 across 3 AWS EKS clusters, our team reduced dependency resolution failures by 40%, cut mean time to recovery (MTTR) for failed batches by 62%, and eliminated 18 hours of weekly manual orchestration overhead. If you’re still using native K8s CronJobs for complex dependency chains, you’re leaving measurable reliability and velocity on the table.
