Developer experience is not a soft concern — it is the measurable output of a platform team. DORA showed that delivery performance predicts organisational performance.

Backstage, Port and Cortex lead the internal developer portal market, but they are three different products: a framework you build, a data platform you model, and a standards engine you adopt. How they compare layer by layer, what they cost, and how to choose.

The model is a CPU. Without an operating system -- the harness -- it's powerful but inert. Reliability is the real work. Prompting is the easiest part.

Replicate data across multiple nodes to improve read scalability, availability, and disaster recovery -- choose your topology (single-leader, multi-leader, leaderless) and sync mode based on your durability/latency trade-offs.
