The concept of DONE have changed in project teams to evolve from “The unit tests are green” to “The software is shippable in production”. Continuous Integration mutated into Continuous Delivery and this process was no longer limited to the DEV teams but had to integrate the OPS team to cover the deployment phases of the applications. Come and discover how the Continuous Integration server Jenkins CI became the nexus of Continuous Delivery orchestrating the phases of complex Application Lifecycle processes. Discover how Jenkins is becoming the lingua franca between DEV teams and OPS teams to deliver applications faster.
