13 min read · enforce cluster standards before objects reach etcd
Bad manifests reach etcd when nothing sits in the admission path. Combine ValidatingAdmissionPolicy CEL, policy engines, and carefully operated mutating or validating webhooks—with Ignore-to-Fail rollout, namespace selectors, and cert-manager TLS—so defaults and denies land before persistence.
13 min read · catch performance regressions in CI before they reach production
Monthly load tests miss regressions that land on every merge. Split smoke, scenario, and stress tiers with k6 and Gatling, gate CI on thresholds, and watch Kubernetes HPA, CPU throttling, and connection pools while the load runs.
14 min read · migrate cluster edge traffic from Ingress to Gateway API safely
Ingress packs routing, TLS, and policy into one object and leans on vendor annotations. Gateway API splits GatewayClass, Gateway, and HTTPRoute by ownership—migrate side by side with ingress2gateway, ReferenceGrant, and RequestMirror before you cut DNS.
13 min read · choose Wasm over containers for latency-sensitive edge logic
Containers still own long-lived services, but edge PoPs need sub-millisecond starts and tiny binaries. Wasm runtimes on Cloudflare Workers, Fastly Compute, and Spin give sandboxed, request-scoped compute—use them for auth gates, routing, and transforms, not for databases.
14 min read · organize GitOps repos for multi-environment Kubernetes fleets
Flat manifest folders break when you add clusters and teams. Separate application repos with Kustomize overlays, a platform infra repo for shared components, and optional environment control-plane config—then wire promotion, CODEOWNERS, and External Secrets so changes land where they belong.
14 min read · detect namespace cost spikes and automate safe remediation
Monthly cloud bills arrive after the damage is done. OpenCost turns allocation into Prometheus metrics; rolling baselines catch namespace spikes; Alertmanager routes critical budget breaches to Argo Workflows that scale down non-critical workloads—after teams have had weeks of visibility first.
13 min read · eliminate deployment 502s with graceful pod termination
Rolling updates and node drains still cause 502s when pods ignore SIGTERM. Combine application drain, PreStop delay for endpoint removal, PDBs for voluntary disruptions, and sidecar-aware termination so users never notice a rollout.
14 min read · scale batch and queue workloads from external events
HPA scales on CPU and memory; queue consumers and batch jobs need queue depth, lag, and schedules. KEDA adds scale-to-zero, ScaledObject for long-lived workers, and ScaledJob for fan-out batches—without paying for idle pods between bursts.
14 min read · isolate tenant workloads with layered quota and network controls
One batch job with unbounded requests can throttle latency-sensitive APIs across a shared cluster. Stack tiered namespaces, ResourceQuotas, LimitRanges, default-deny NetworkPolicy, and optional dedicated node pools into one isolation model with cost labels finance can reconcile.
14 min read · attribute namespace spend and enforce resource budgets
Cloud billing shows cluster totals, not which namespace burned budget on unused CPU requests. ResourceQuotas cap team consumption, LimitRanges shape pod profiles, and OpenCost or Kubecost close the attribution loop—with labels finance can reconcile.
14 min read · attribute cluster spend and automate cost guardrails
Shared Kubernetes clusters hide who spends what until finance gets the bill. FinOps connects namespace-level usage to dollars, eliminates waste through right-sizing, and automates quotas and alerts without blocking delivery.
12 min read · reduce engineering discovery friction with a catalog-first portal
When ownership lives in Slack threads and deploy docs rot in Confluence, delivery slows. This guide shows how Backstage unifies discovery through catalog-info.yaml, custom plugins, scaffolder templates, and catalog-first rollout practices.
13 min read · reduce delivery friction through a standardized internal platform
When each team owns a different pipeline style, delivery slows and platform risk grows. This guide shows how to build an Internal Developer Platform with a deployment abstraction layer, service catalog, policy gates, and centralized secrets.
14 min read · Kubernetes security hardening for production clusters
Default clusters are easy targets for RBAC sprawl, open APIs, and plaintext etcd. This guide walks through control plane flags, Pod Security Standards, default-deny networking, node sysctl hardening, and Vault-style secrets—with a phased rollout plan.
12 min read · hybrid platform operations and unified control planes
Hybrid estates split teams across incompatible tooling and slower incident response. This article outlines a single operational layer: shared deployment interfaces, normalized observability, policy-as-code, mesh-aware connectivity, and identity that spans both runtimes.
