Practical articles on AI, DevOps, Cloud, Linux, and infrastructure engineering.
Building visibility into cloud costs that actually drives action. The dashboards we look at, the alerts that fire, and the queries we run.
Concrete systemd unit patterns that reduced flakiness: restart policies, resource limits, and structured logs.
How a small team moved from single-region risk to a simple active/passive multi-region setup without doubling complexity.

A real story of removing console-only changes, adding drift detection, and getting Terraform back in charge.
We run ~200 Lambda functions. Cold starts, memory tuning, and the cost-vs-latency trade-offs that actually move the bill.
Design for region failure. Active/passive and active/active, data replication, and failover testing.
