Deep technical write-ups, architecture breakdowns, and lessons from real engagements.
For years, observability meant three disconnected silos and a different agent for each vendor. OpenTelemetry (OTel) is the industry-wide answer: a single set of APIs, SDKs, and a wire protocol (OTLP)…
Every system has failure modes you have not met yet. Chaos engineering is the discipline of meeting them on your schedule, in daylight, with a rollback ready, instead of at 3am during a real outage.…
Scanning images at build time tells you about known bad code. It says nothing about the compromised process spawning a shell in your payments pod at 2am. Runtime security watches actual behavior and…
Incidents are inevitable; trauma is optional. The difference between a team that learns from outages and one that quietly rage-quits is process, clear roles, blameless review, and a hard line on…
Most Kubernetes bills are not expensive because of traffic, they are expensive because of slack . Over-provisioned requests, idle nodes, and forgotten volumes quietly compound. FinOps is engineering…
For years, getting deep visibility meant injecting sidecars, patching binaries, or bolting agents onto everything. eBPF flips that: you attach safe programs to the kernel and watch every syscall,…
A deploy that needs a human watching Grafana is not a deploy strategy, it is a hostage situation. Progressive delivery makes the release measure itself and roll back automatically when the numbers…
Autoscaling looks simple in a demo and gets subtle fast in production. Three controllers operate on different axes, and the failure modes only show up under real traffic. This is the mental model we…
Dashboards nobody opens are just expensive wallpaper. Part 3 is about signals that change behavior. Instrument the four questions Is the data fresh? Is the data complete? Is the data correct? Who is…
Batch gets you correctness; streaming gets you freshness . In Part 2 we wire up a Kafka ingestion path that is safe to operate at 3am. Create a topic with sane defaults Set partitions and retention…
