>_ Kubernetes Ingress Architecture Series ▶ Part 0 — You Are Here The Decision Layer: Four Paths, Four Failure Modes How to evaluate the ingress-nginx retirement before picking a direction >_ Part 1 Gateway API Is the Direction. Your Controller Choice Is the Risk. Failure modes, Day-2 behavior, and the controller decision that matters after…
The Kubernetes Gateway API project is not forcing you to migrate away from Ingress NGINX. There is no hard cutoff date, no deprecation warning in your cluster logs, no upgrade blocker. The project has simply moved on — and that quiet, undramatic shift is exactly what makes it operationally dangerous. Ingress NGINX is no longer…
Kubernetes 1.35 in-place pod resize graduates to stable — and with it, six years of a hidden operational tax on stateful workloads comes to an end. If a container needed more CPU or memory, the only safe answer was a restart. That design made sense for stateless services. It was painful for everything else. Increase…
Your containerd metrics look healthy. Pod density is climbing. Node CPU is stable. Memory pressure is low. Then somewhere around 800–900 containers per node, something quiet happens: containerd-shim processes begin accumulating memory. Each failure signature maps directly to the diagnostic loops in the Rack2Cloud Kubernetes Day-2 Method. For environments running a service mesh alongside containerd,…
The Kubernetes VMware migration path is not what most platform teams expect. Thirty-three percent of enterprises evaluating VMware alternatives are selecting Kubernetes as their primary control plane for the transition. Not as the destination — as the mechanism. The distinction matters architecturally, and most of the coverage on this topic misses it entirely. Kubernetes does…
Kubernetes day 2 failures are not random. The same five failure modes surface every month — and the tells are always there if you know which metrics to watch. Day 1 is shipping the cluster. Day 2 is living with it. And Day 2 has patterns. Not bugs that are unique to your environment —…
Kubernetes networking has historically been split across two layers: the Container Network Interface (CNI), which handles pod-to-pod connectivity and network policy, and the service mesh, which adds application-layer features like mutual TLS, traffic routing, and observability. For years the common architecture looked like this: The rise of eBPF-based networking has started to collapse these layers….
In 2026, the Azure Landing Zone vs AWS Control Tower decision remains one of the most consequential governance choices an architect makes before a single workload goes live. Both solve the same problem — a secure, governed, scalable multi-account foundation — but they solve it in fundamentally different ways, with fundamentally different operational consequences downstream….
