DevOps — major processes & flow maps
CI/CD pipeline — Every commit triggers an automated pipeline. Build, test, scan, deploy in sequence. Failures at any stage block progression. The pipeline is the single source of truth for deployment readiness.

4. Deployment strategy decision
5. Phases A–F (DevOps emphasis)
| Blueprint phase | DevOps emphasis | Key practice |
|---|---|---|
| A Shape | Include operability requirements (SLOs, monitoring needs) | Shift-left on operational thinking |
| B Plan | Pipeline design; deployment strategy; environment planning | IaC from the start |
| C Build | CI: automated build, test, scan on every commit | Trunk-based development; small, frequent commits |
| D Verify | Automated test pyramid; security scanning; performance testing | Quality gates in the pipeline |
| E Release | CD: automated deployment; canary/blue-green; feature flags | Make deployments boring |
| F Learn | Monitoring, alerting, incident response, post-mortems | Production feedback closes the loop |

CI/CD pipeline — Every commit triggers an automated pipeline. Build, test, scan, deploy in sequence. Failures at any stage block progression. The pipeline is the single source of truth for deployment readiness.
Infinity loop — DevOps is not a linear process; it is a continuous cycle. Planning incorporates operational learnings. Code includes infrastructure. Testing includes production-like environments. Monitoring informs the next planning cycle.
Incident response — Structured, not ad-hoc. Severity determines response level. Incident commanders coordinate complex responses. Post-mortems extract learning from every significant incident.
Deployment strategies — Choose based on risk tolerance. Rolling updates are simplest. Canary releases test with a subset of traffic. Blue-green provides instant rollback. Feature flags decouple deployment from user-visible release.
