At the heart of traditional Continuous Delivery is the deployment pipeline. A build is generated, promoted through several testing environments and if it passes tests and is aligns with business needs is deployed to Production. This model struggles to account for complex systems where releases involve numerous inter-related builds and/or components that don't fit neatly into the model of "builds" such as incremental content migrations, configuration changes, database schema updates, or report / ETL migrations. This presentation examines the limitations of the build promotion model, architectural approaches for adapting applications to that model, and deployment approaches that realign the release pipeline around the migration of value, rather than the migration of builds.
