Cilium ENI mode architecture, Gateway API resource configuration, performance optimization, Hubble observability, BGP Control Plane v2 deep-dive guide

NGINX Ingress Controller EOL response, tiered gateways for agentic workloads, Gateway API architecture, GAMMA Initiative, AWS Native vs open source solution comparison (AWS LBC, Cilium, NGINX Gateway Fabric, Envoy Gateway, kGateway, Kong), Cilium ENI integration, migration strategy and benchmark plans

Dissects the internals of Amazon VPC CNI along three axes. The L3 routed mode datapath (veth, ip rule, 169.254.1.1), ipamd's warm pool, Prefix Delegation, and IP cooldown algorithms, and the eBPF-based NetworkPolicy architecture

The Network Flow Monitor agent's TCP callbacks, userspace aggregation, Kubernetes metadata, OTLP publishing, and EKS troubleshooting.

Why the same workload shows different CPU utilization across instance sizes and generations, which KPIs to compare instead, where throttling and scheduling wait are observed, a Pod sizing baseline, and how to decide on mixed node pools.

Observability implementation guide for EKS Hybrid Nodes — covers Cluster Insights configuration self-diagnosis, CloudWatch Container Insights hybrid configuration (RUN_WITH_IRSA), NVIDIA GPU metric integration, a Cilium Hubble-based eBPF dashboard, and Network Flow Monitor applicability analysis.
