14 min read · debug kernel-level latency and network issues in production
Application metrics cannot explain TCP retransmissions, cgroup scheduling delays, or syscall hot paths. eBPF runs sandboxed programs in the Linux kernel to observe those signals with minimal overhead—without strace, sidecars, or kernel rebuilds.
14 min read · trace every request path across microservices in Kubernetes
One user request can cross dozens of services before it returns. Logs and metrics alone cannot show where latency or errors appear in the chain. This guide deploys the OpenTelemetry Operator, agent and gateway collectors, auto-instrumentation, and W3C context propagation to Tempo.

Jaeger, Prometheus, and Fluentd as three separate stacks multiply ops cost and break correlation. This guide deploys agent and gateway Collectors with memory limits, tail sampling, exporter queues, and Kubernetes Helm patterns.
12 min read · collapse incident tooling into one auditable Slack workflow
On-call engineers still context-switch between PagerDuty, Grafana, kubectl, and wikis while minutes burn. This guide wires Prometheus Alertmanager into a Slack bot that enriches alerts, posts runbook actions, and executes approved remediation with RBAC.
11 min read · ship faster PR feedback without shared staging contention
Shared staging clusters turn into queues and config drift. This guide shows how to provision one namespace per pull request with Helm and GitHub Actions, enforce quotas, route preview traffic, and delete resources when the PR closes.
12 min read · reduce release blast radius with metric-driven progressive rollouts
Rolling updates alone still expose every user to risky changes at once. This guide combines Flagger-style canary traffic with feature flags so you can validate releases under real load and roll back fast without a full outage.
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 · automate database schema changes through CI/CD and GitOps
When app deploys and schema changes run on different tracks, production breaks fast. This guide turns migrations into first-class delivery artifacts with Flyway or Liquibase, forward-safe expand-contract rollouts, and GitOps-aware execution order.
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 · GitOps delivery with Argo CD or Flux on Kubernetes
Git as the contract of record stops silent drift across clusters. Compare Argo CD and Flux patterns—from install snippets to policy hooks—and adopt guardrails for secrets, observability, and audit-ready rollouts.
11 min read · secrets, credentials, and certificates in DevOps CI/CD pipelines
CI/CD needs secrets, yet sprawl and logs multiply risk. This guide covers a centralized pattern, Vault with GitLab, Kubernetes CSI mounts, and guardrails for rotation, access, and audit.
10 min read · resilience engineering and controlled failure testing in DevOps
Most outages are not caused by unknown bugs but by untested failure behavior. This guide explains how to run hypothesis-driven chaos experiments safely, measure impact, and turn findings into repeatable resilience improvements.
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.
14 min read · infrastructure strategy and platform architecture decisions
A CTO asks for faster releases, security asks for stricter isolation, and finance asks for predictable costs. Containers and virtual machines answer these demands differently. This guide unpacks the real tradeoffs and helps DevOps teams choose architecture with fewer surprises in production.
