Pods, Deployments, and Services: a friendly guide to how Kubernetes runs your app
Kubernetes can feel like a new language at first, but three concepts map tightly to real-world roles: Pods are the actual workers, Deployments are the manager who hires and replaces...
Scaling ML training with Airflow Dynamic Task Mapping and Kubernetes
Orchestrating machine learning pipelines is where classic DevOps tooling meets model-driven complexity. If you need many parallel training runs (hyperparameter sweeps, per-shard training, or large-scale feature engineering), combining Apache Airflow’s...
Make the first commit feel like home: self‑service platforms and ephemeral environments for faster developer onboarding
Bringing a new engineer into a codebase often feels like handing them a map without a compass. The most common friction points aren’t technical skill — they’re the busywork: installing...
Intro to Observability as Code: Managing Dashboards with GitOps
Observability as code treats dashboards, alerts, data sources, and SLOs like application code: versioned, reviewed, and deployed through automation. For teams running Grafana, Prometheus, and OpenTelemetry, that typically means storing...
Moving Prometheus off the single-node island: remote_write to Grafana Mimir
Prometheus is great for scraping and answering questions about what your application is doing right now, but when teams want reliable, long-term, or global views across clusters they often add...
Building a secure CI/CD pipeline with ephemeral secrets and automated scanning
Modern CI/CD pipelines accelerate delivery — and, if left unsecured, they accelerate breaches. Two failure modes show up again and again: long-lived secrets embedded in repos or CI variables, and...
Intro to Observability as Code: Managing Dashboards with GitOps
Observability dashboards are as important as the metrics and logs they visualize — but they’re also easy to lose track of when dashboards are edited by hand in a running...
Practical steps to secure your CI/CD: ephemeral secrets, secret scanning, and artifact signing
CI/CD pipelines are the production lines of modern software — and like any factory, they’re only as safe as the tools, materials, and access controls around them. Recent supply‑chain incidents...
