We track the four DORA metrics plus a handful of others. The trade-off between what's measurable and what's meaningful, and how we use the numbers.
Design for region failure. Active/passive and active/active, data replication, and failover testing.
We've run canary deploys on most services for two years. The mechanics are easy; the metrics that decide "promote or roll back" are where the design is.
A real story of removing console-only changes, adding drift detection, and getting Terraform back in charge.
We use blue-green for stateful services where canary doesn't fit. The actual mechanics, the data-layer subtleties, and when blue-green isn't the right answer.
How a small team moved from single-region risk to a simple active/passive multi-region setup without doubling complexity.
We collect ~800GB of logs per day across our fleet. The shape of our logging stack, what we keep, what we drop, and what we'd build differently.
A working Prometheus stack for a 40-node cluster: what we deploy, what we tune, and what we wish we'd known about cardinality two years ago.
A focused look at the techniques that shrink container images: which actually pay off, which are folklore, and the discipline that keeps images small over time.
We've had to restore a Kubernetes cluster from backup twice. Once it worked. Once it took 14 hours. Here's the strategy we run now.
