5 ways GitLab pipeline logic solves engineering problems

What this post added

This post details five specific engineering problems solved by GitLab's advanced CI/CD pipeline execution model: monorepos (parent-child pipelines + DAG execution), microservices (cross-repo, multi-project pipelines), multi-tenant/matrix deployments (dynamic child pipelines), and MR-first delivery (merge request pipelines, merged results, and workflow routing). It provides concrete configuration examples and explains the technical benefits of each pattern, such as reduced pipeline runtime, improved cross-service breakage detection, manageable deployment matrices, and testing what will actually land on main.
