CI/CD Paradigms, Concepts & Philosophies
Read the full guide on docs.beyondyou.my.idCI/CD is often treated as a tooling problem — pick Jenkins or GitHub Actions, write some YAML, and you’re done. But the real value of CI/CD comes from understanding the underlying paradigms: what continuous integration actually means, how continuous delivery differs from continuous deployment, and why these practices were developed in the first place.
Key Takeaways
- Continuous Integration: Developers merge code to trunk frequently (at least daily); each merge triggers automated builds and tests
- Continuous Delivery: Every change that passes CI is automatically prepared for production release; the actual deployment is a manual decision
- Continuous Deployment: Every change that passes CI/CD is automatically deployed to production — no human gate
- CI/CD is a cultural practice, not just tooling — it requires team discipline and organizational buy-in
- The goal is to reduce the painful “integration phase” where long-lived branches are merged and everything breaks
Quick Overview
The progression from manual releases to CI/CD follows a maturity curve. Level 1: manual builds and deployments. Level 2: automated builds on commit (CI). Level 3: automated deployments to staging (Continuous Delivery). Level 4: automated deployments to production (Continuous Deployment). Most organizations operate at Level 2 or 3 — Continuous Delivery with a manual approval gate before production is the pragmatic sweet spot for regulated industries.
The key insight from the original CI pioneers (Kent Beck, Martin Fowler) was that integration is painful because it’s done infrequently. By integrating continuously — merging small changes frequently — you surface conflicts early when they’re cheap to fix.
