CI/CD — continuous integration and continuous delivery (or deployment) — is the practice of automating the build, test, and deployment pipeline so that every code change is validated and shipped without manual intervention.
CI (continuous integration) covers the build and test stages. Every commit triggers a pipeline that runs tests, linting, type checks, security scans, and produces a deployable artefact. CD (continuous delivery / deployment) takes that artefact and ships it — to staging automatically, and to production either automatically (continuous deployment) or with a manual approval gate (continuous delivery).
Major platforms in 2026: GitHub Actions (dominant), GitLab CI, CircleCI, Buildkite, and specialised tools like Vercel and Netlify for JAMstack. Nagro Solutions runs GitHub Actions for CI on every client project and configures per-project deploy strategies (blue-green, canary, or straight cutover) based on risk.
