Continuous delivery is an approach to software development whereby at all times during the development process the software is kept in such a state that it could be successfully released into production. Continuous delivery requires continuous integration, where developers are every day checking their code into a version-controlled repository, from which it is pulled by a build server that compiles the application and subjects it to automated tests to ensure that the application is working as expected. Continuous delivery goes beyond agile continuous integration by also ensuring that the application is tested in an environment that’s as similar as possible to the production environment; and by leveraging a high degree of deployment automation so that the application can be deployed on-demand when product managers want the latest version to go live.
Continuous delivery is a prerequisite of continuous deployment, in which application updates are actually released to live production very frequently – sometimes multiple times a day. Continuous deployment is utilized by many online businesses including market leaders like Amazon, Google, and Facebook.
Continuous delivery provides substantial benefits to the software makers and IT service companies that practice it:
