Hands-on comparison of Kafka/Redpanda networking in Kubernetes using sockperf on a three-node EKS cluster (m5.2xlarge): nodePort yields the lowest latency, load balancer is next, and adding a proxy such as Envoy proxy raises tail latency and halves efficiency at scale. Practical build details include StatefulSets with headless and per-broker services, advertised addresses via DNS or node IPs, NVMe local storage with XFS and LVM striping, CPU pinning for brokers, and tuning producers/consumers and partition counts to balance throughput, latency, and metadata overhead.
