Finally, you will examine what a typical Java continuous delivery build pipeline looks like and learn the fundamentals of each stage in the pipeline.
Setting the Scene
Continuous delivery (CD) is fundamentally a set of practices and disciplines in which software delivery teams produce valuable and robust software in short cycles. Care is taken to ensure that functionality is added in small increments and that the software can be reliably released at any time. This maximizes the opportunity for rapid feedback and learning, both from a business and technical perspective. In 2010, Jez Humble and Dave Farley published their seminal book Continuous Delivery (Addison-Wesley), which collated their experiences of deploying software delivery projects around the world, and this publication is still the go-to reference for CD. The book contains a valuable collection of techniques, methodologies, ...
