codelivery

Code delivery, or codelivery, refers to the set of practices and tools used to move software code from development to running systems. The goal is to automate, standardize, and accelerate releases while preserving reliability and security. Codelivery covers the full lifecycle from source control to production deployment, including building, testing, packaging, and deploying code artifacts.

Key components include version control systems such as Git for tracking changes and collaboration; continuous integration systems that automatically build and test code on changes; build tools and package managers that compile, assemble, and package artifacts; artifact repositories that store builds for distribution and traceability; deployment and configuration automation that release artifacts to test, staging, and production environments; and monitoring and feedback mechanisms that verify behavior after deployment.

Delivery strategies vary. Push-based pipelines trigger deployments after successful builds, while pull-based models deploy via automated acceptance gates. Deployment patterns such as blue-green, canary, and rolling updates reduce risk by limiting exposure to new changes. Feature flags can decouple release timing from code completion.

Governance and security considerations include code review, access controls, signed artifacts, reproducible builds, and audit trails. Site reliability engineering and DevOps practices emphasize observability, rollback procedures, and post-deployment validation.

In practice, codelivery is associated with continuous delivery and continuous deployment philosophies, but not all organizations automate to production; some use staged pipelines and manual gates. Effective codelivery relies on reliable tooling, clear ownership, and a culture that prioritizes automation, repeatability, and safety.
