The whole in-scope estate laid out as one pipeline so later lessons have somewhere to land: what ingests, what transforms, what stores, what catalogs, what queries, what orchestrates, and what governs — and the handful of services that appear in all four domains.

Content current as of 2026-10.

Lessons
