The remedy is to integrate the testing, deployment, and release activities into the development process. Make them a normal and ongoing part of development so that by the time you are ready to release your system into production there is little to no risk, because you have rehearsed it on many different occasions in a progressively more production-like sequence of test environments. Make sure everybody involved in the software delivery process, from the build and release team to testers to developers, work together from the start of the project.
It makes sense that the developers will need to build binaries rather than take pre-prepared binaries built elsewhere, so this constraint can be relaxed for those deployments. Even on developer workstations, though, we try as much as possible to deploy and manage things in the same way. The Release Candidate What is a release candidate? A change to your code may or may not be releasable. ” then the answer could only be a guess. It is the build, deployment, and test process that we apply to that change that validates whether the change can be released.
A deployment pipeline is, in essence, an automated implementation of your application’s build, deploy, test, and release process. Every organization will have differences in the implementation of their deployment pipelines, depending on their value 3 4 Chapter 1 The Problem of Delivering Software stream for releasing software, but the principles that govern them do not vary. 1. 1 The deployment pipeline The way the deployment pipeline works, in a paragraph, is as follows. Every change that is made to an application’s conﬁguration, source code, environment, or data, triggers the creation of a new instance of the pipeline.
