DevOps, 12-Factor, & Platform Engineering
summary
Traces DevOps to the Theory of Constraints, argues throughput beats cost, and shows how 12‑Factor apps reduce deployment friction; demonstrates an Internal Developer Portal (Cortex) that centralizes ownership, integrates PagerDuty, Slack, Buildkite, SonarQube, Jira and GitHub, and exposes scorecards that gamify standards. The portal gates releases via API when production readiness fails, cascades policy changes instantly across thousands of services, and measurably cuts toil and context switching while improving DORA-style metrics. gated releases Cortex portal
