1. Test at Every Stage, Not Just at the End
A reliable pipeline runs unit, integration, and security tests at every stage, not only before production deployment. The earlier an issue is caught, the cheaper it is to fix.
2. Automate Infrastructure as Rigorously as Code
Infrastructure as Code (Terraform, Ansible) lets you version and test infrastructure changes with the same rigor as application code.
3. Deploy in Small Increments
Frequent, small deployments are easier to validate and roll back than large, infrequent production releases.
4. Monitor After Deployment, Not Just Before
A complete CI/CD pipeline includes a post-deployment monitoring phase, with automatic alerts in case of regression.
5. Document the Pipeline Itself
A well-documented pipeline lets the whole team understand and evolve the deployment process, without depending on a single person.
