Continuous Deployment

Continuous Deployment Overview

Continuous Deployment is the practice of continuously pushing to production new versions of software under development. In organizations like Facebook and Amazon, software is deployed thousands of times each day.

Continuous Deployment vs. Continuous Integration (CI) and Continuous Delivery

  • Continuous Integration is a software development practice in which you build and unit-test software every time a developer checks in new code.
  • Continuous Delivery (CD) is a software development practice in which continuous integration, automated testing, and automated deployment capabilities allow software to be developed and deployed rapidly, reliably and repeatedly with minimal manual overhead.
  • Continuous Deployment - Continuous Deployment is a software development practice in which every code change goes through the entire pipeline and is put into production, automatically, resulting in many production deployments every day.

 With Continuous Delivery your software is always release-ready, yet the timing of when to push it into production is a business decision, and so the final deployment is a manual step. With Continuous Deployment, any updated working version of the application is automatically pushed to production. Continuous Deployment mandates Continuous Delivery, but the opposite is not required.

Continuous Deployment Best Practices

L;lostechies.com;Blue-Green Deployment - How to Achieve Zero Down-Time Deployment;https://lostechies.com/gabrielschenker/2016/05/23/blue-green-deployment/;NA;2016;;;These days our customers expect their applications to be up and running all the time and literally experience no down-time at all ever. At the same time we should be able to add new features to the existing application or fix existing defects. Is that even possible? Yes, it is, but it is not for free. We have to make a certain effort to achieve what is called zero-downtime deployments.

L;pagerduty.com;Are You Ready for Continuous Deployment? - Continuous Deployment vs. Continuous Delivery;https://www.pagerduty.com/blog/are-you-ready-for-continuous-deployment/;Chris Riley;2016;;;There is a large gap between the understanding of modern processes and technologies, and actually doing something with them. In the DevOps movement, many of the core functions have met wide adoption, such as orchestration, release automation, and analytics. But what have not been as widely adopted are the end-to-end processes of continuous delivery and deployment.
