Ingress NGINX Retirement — Migrate to Gateway API
The Kubernetes community announced the retirement of ingress‑nginx in March 2026, leaving the final v1.15.1 release without future security patches or bug fixes. This article presents a practical, zero‑downtime migration framework for affected clusters: assess current ingress usage, map feature parity, and choose among three primary targets — F5/NGINX Ingress Controller (v5.4.0), Gateway API with Envoy Gateway, or cloud provider controllers (ALB, GKE, AWS Load Balancer Controller). It describes risk factors (feature gaps, operational blast radius, security implications), three migration patterns (parallel controllers, blue/green clusters, Gateway API progressive migration), a four‑phase execution timeline (Preparation, Pilot, Production, Cleanup over ~10 weeks), and recommended tooling (migration assessment tools, conformance tests, Helm/GitOps automation). The guide stresses starting early to avoid running unmaintained software and planning eventual Gateway API adoption.
The ingress‑nginx deprecation removes future security updates for a widely used controller and forces large numbers of production Kubernetes clusters to plan and execute migrations; choices and migration patterns will affect uptime, security posture, and future networking architectures across cloud‑native deployments.

API Gateway Patterns: Kong vs Envoy vs Traefik
This technical comparison evaluates three popular API gateway/proxy options—Kong, Envoy, and Traefik—covering roles, configuration methods, feature sets, extensibility, and deployment patterns. Kong is described as a full-featured API management platform (originating from Nginx) with a large plugin ecosystem and commercial support options. Envoy is positioned as a high-performance L4/L7 proxy and the data plane for service meshes like Istio, offering WASM extensibility and advanced routing. Traefik emphasises Docker/Kubernetes-native service discovery and low configuration complexity. The article lists common API-gateway patterns (BFF, versioning, rate-limiting tiers, request transformation), provides example configs, compares capabilities (auth, rate limiting, load balancing, memory footprint), and gives recommendations for when each solution is appropriate.
Kubernetes Networking: MetalLB, Nginx Ingress, NetworkPolicy
This technical how-to (Part 2) describes converting a bare-metal kubeadm cluster from NodePort to a production-style network: installing MetalLB to provide real LoadBalancer IPs, deploying the community Nginx Ingress Controller as a single HTTP/HTTPS entrypoint, updating services to ClusterIP, creating Ingress resources with hostname-based routing (app.oty-k8s.local, api.oty-k8s.local), configuring local DNS, and applying Kubernetes NetworkPolicy manifests to enforce pod-to-pod allowlists. The post includes concrete kubectl commands, example MetalLB IP pool (192.168.1.200-192.168.1.220), guidance on networking modes (Layer 2 ARP advertisement), critical YAML pitfalls (Ingress API version, NetworkPolicy AND/OR indentation), and a seven-step test suite that verifies allowed and blocked connections. All manifests are published in a linked GitHub repository. Published 2026-05-13.
Checklist for Choosing an AI Gateway in 2026
A 2026 guide explains how engineering teams should evaluate AI gateways by starting with deployment constraints (data residency, VPC, on‑prem, air‑gapped, multi‑cloud) and then assessing six production‑grade capabilities: multi‑model routing and fallback, token‑level cost attribution, input/output guardrails, MCP and agent support, deep observability, and performance at scale. The article contrasts lightweight open‑source proxies, SaaS gateways, and unified enterprise platforms (highlighting TrueFoundry as an example), and recommends asking vendors practical questions about data flows, failover, workflow traces, per‑agent RBAC, MCP integrations, and certification evidence.
