Infrastructure

Infrastructure used to be something you bought and bolted together. Now it’s something you write. The shift to cloud-native, infrastructure-as-code approaches has made the boundary between software engineering and operations increasingly thin — and intentionally so.

The upside is enormous: reproducible environments, version-controlled configuration, automated scaling, and deployments that can be reviewed like any other pull request. The downside is that the surface area of what an engineering team is responsible for has expanded significantly. Knowing how your application runs in production is no longer optional knowledge.

Posts here cover the practical side of this — building reliable infrastructure on the cloud, managing costs, choosing the right primitives, and the real-world experience of running systems at scale rather than just designing them.
