Covers two core jobs: building resilient workloads and diagnosing live incidents. Includes a triage sequence to identify failure domains in under 2 minutes, deep dives into EKS Tier-0 components (CoreDNS, VPC CNI, kube-proxy, EBS CSI, Load Balancer Controller), and common failure modes like conntrack exhaustion, ephemeral port exhaustion, NLB/NAT idle timeouts, DNS query limits, and security group connection tracking. Provides concrete kubectl commands, evidence collection scripts, and a step-by-step incident playbook for Tier-0 failures. ## Full article daily.dev links to this article rather than hosting it.
