Continuous deployment

We believe organizations should adopt continuous deployment practices whenever possible. Continuous deployment is the practice of automatically deploying every change that passes automated tests to production. This practice is a key enabler of fast feedback loops and allows organizations to deliver value to customers more quickly and efficiently. Continuous delivery differs from continuous deployment in that it only requires that code can be deployed at any time; it doesn't require that every change actually is deployed to production. We've hesitated to move continuous deployment into the Adopt ring in the past, as it’s a practice that requires a high level of maturity in other areas of software delivery and is therefore not appropriate for all teams. However, Thoughtworker Valentina Servile’s recent book Continuous Deployment provides a comprehensive guide to implementing the practice in an organization. It offers a roadmap for organizations to follow in order to achieve the level of maturity required to adopt continuous deployment practices.

If you are wondering “What comes after agile?,” you should look towards continuous delivery. While your development processes may be fully optimized, it still might take your organization weeks or months to get a single change into production. Continuous delivery focuses on maximizing automation including infrastructure as code, environment management and deployment automation to ensure your system is always ready for production. It is about tightening your feedback loops and not putting off anything until the end. Continuous delivery is not the same as continuous deployment, which means deploying every change to production. Continuous delivery is not a cowboy show. It puts you in charge of your production environment. The business can pick and choose what and when to deploy. If you think you’ve nailed agile development, but aren’t considering how to achieve continuous delivery, you really haven’t even started.

The past 2 years or more has seen a proliferation of continuous integration tools and platforms leading to substantial innovation in the build and release space. Distribution of builds is one such innovation and yet another is the way in which builds are now structured to make greater use of automation in various stages of the build. Build pipelines help to provide greater insight into the quality of each build and the environments to which they have been deployed. A natural expansion of the build pipeline meme is the adoption of continuous deployment techniques, where the intention is to extend the build pipeline into the production environment. This relies on automated deployment techniques and authorization mechanisms built into the continuous integration toolset. One of the key benefits is the ability to move new functionality into production rapidly and reliably.
