Prior to DevOps, the “throw it over the wall” model dominated. Once code was deemed complete by Dev, it was handed to Ops for deployment. This link was weak, asynchronous, and document-heavy. Devops link
Continuous Integration (CI) and Continuous Delivery (CD) form the technical backbone of the link. CI links developers together (merging code frequently) and links code to quality assurance (automated testing). CD links a tested artifact directly to production environments. Automation eliminates the manual handoffs that were the primary source of friction. A successful CI/CD pipeline ensures that what Dev commits is what Ops deploys, with no translation errors. Kim, G
