How did a change you made on your laptop get from your laptop to production?

A typical path for a change from a developer’s laptop to production involves several stages: 1) Version Control – the developer commits code or configuration changes to a Git repository. 2) Build & Test – a CI system (e.g., Jenkins, GitHub Actions, GitLab CI) pulls the commit, runs unit tests, linting, and builds artifacts. 3) Artifact Store – successful builds are stored in a registry or artifact repository (Docker Hub, ECR, Nexus). 4) Staging Environment – the CI pipeline deploys the artifact to a staging or pre‑production environment where integration and smoke tests run. 5) Approval – manual or automated approval gates may be required before promotion. 6) Production Deployment – the artifact is promoted to production, often via a CD tool (ArgoCD, Spinnaker, or a cloud‑native service). 7) Monitoring & Rollback – after deployment, monitoring tools check health; if issues arise, a rollback to the previous stable version is triggered. This pipeline ensures that changes are tested, reviewed, and safely promoted, reducing the risk of breaking production.
