How does a large 50-year-old company go from purchasing much of its technology and working with yearlong release cycles to building multiple products in-house and releasing daily? Jon Moore traces the changing set of tools, techniques, and attitudes that have powered (and still power) this transformation at Comcast over the last decade, mapping out a path you can follow in your own company.
Jon starts by describing the monolithic waterfall projects delivered by separate development, QA, and operations teams before exploring continuous delivery of service-oriented architectures by independent DevOps teams. Platform-wise, Jon covers everything from bare metal servers in private data centers to VMs in private and public clouds to container orchestration systems and platforms as a service. Practice-wise, he explores month-long Scrum sprints with manual testing and lean, Kanban-style workflows with substantial testing and operational automation. If there’s a popular open source project in this space, Comcast has probably used it.
Due to the ever-changing business and technology landscape and the length of time this journey has covered, you’ll likely recognize your company’s situation at some point in this story; you can use this understanding to map your own path forward.
