Term Kind Topic What it is
Cluster Split Axis concept Cluster Architecture The dimension along which the estate is divided into clusters — the single decision that determines both blast radius and operational load.
Leaky Abstraction Cost concept Abstraction Level Choice What a consumer pays when a platform abstraction hides a mechanism they must nonetheless understand to diagnose or tune it.
Platform Contract concept Platform APIs The platform's promise to its consumers about interface stability, behaviour and support, treated with the same seriousness as an external API.
Preventive Control Placement concept Guardrails vs Gates Choosing where in the lifecycle a control acts — at authoring, at admission or after the fact — which determines both its strength and its cost.
Service Catalogue Entry concept Internal Developer Platform The record that makes a service a first-class object in the platform — owner, dependencies, docs, runbooks and health in one place with a single identity.
