SLIs, SLOs, and SLAs — a practical guide for modern services
Reliability promises live at three levels: SLIs (what you measure), SLOs (what you aim for), and SLAs (what you contract). Getting them right means measuring what users actually experience, setting...
Carbon-aware autoscaling: automating lower cloud carbon footprints
Sustainable DevOps adds environmental responsibility to the usual DevOps goals of speed and reliability. One of the most practical levers in that space is automation: letting systems dynamically shift work...
Stop wasting money on idle cloud resources: a beginner’s practical guide
Cloud bills feel like a mysterious vinyl record — they keep spinning even when nothing new is playing. The good news: most “mystery” cloud spend comes from idle, forgotten, or...
Gateway API: the easy way to think about modern Kubernetes ingress
Kubernetes networking has a habit of evolving under our feet. Lately the change that matters for many teams isn’t the CNI or a new load‑balancer trick — it’s the Gateway...
Provenance-first: making AI-generated Kubernetes manifests verifiable and safe
AI can write a tidy Deployment or Service faster than manual YAML, but the convenience carries a familiar risk: who (or what) actually owned the final manifest, and can you...
Hybrid pipelines for auto-summarizing incident reports: balancing clarity, structure, and privacy
Incident reports — whether they come from a hospital safety team, a cloud operations post‑mortem, or a factory floor logbook — are a peculiar genre: long, detail-rich, often written under...
SLOs for the age of LLMs: practical SLIs, SLOs, and SLAs when "quality" is a moving target
Generative AI has changed what we mean by “service quality.” For traditional web APIs you measured uptime and latency; for large language model (LLM) services you must also measure correctness,...
Linking metrics to traces with exemplars: faster latency debugging in Prometheus and Grafana
Aggregated metrics are great for spotting trends — but they’re lousy at telling you which single request caused a spike. Exemplars bridge that gap: they attach a tiny breadcrumb (usually...
