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;martinfowler.com;BlueGreenDeployment;http://martinfowler.com/bliki/BlueGreenDeployment.html;NA;NA;;;One of the goals that my colleagues and I urge on our clients is that of a completely automated deployment process. Automating your deployment helps reduce the frictions and delays that crop up in between getting the software "done" and getting it to realize its value. Dave Farley and Jez Humble are finishing up a book on this topic - Continuous Delivery. It builds upon many of the ideas that are commonly associated with Continuous Integration, driving more towards this ability to rapidly put software into production and get it doing something. Their section on blue-green deployment caught my eye as one of those techniques that's underused, so I thought I'd give a brief overview of it here.
L;airpair.com;Continuous Deployment For Practical People;https://www.airpair.com/continuous-deployment/posts/continuous-deployment-for-practical-people;Mike Mooney;2015;;;Over the last few years, there has a been a lot of great progress in the development community around DevOps, Continuous Integration, Continuous Delivery, and Continuous Deployment. Technology companies have been embracing these ideas of smaller, faster development cycles, and getting code written, integrated, tested, and deployed as quickly as possible. However, there has been a growing opinion that in order to do continuous deployment "right", you need to meet some minimum requirement of developers deploying directly to production all day long. Unfortunately this approach can be a little overly dogmatic for many companies and scares them off before they can find some less extreme ways to improve their development process by incrementally adding the continuous deployment principles that can help them the most.


L;stackoverflow.com;Discussion: How do you continuously deploy a large system consisting of several applications?;http://stackoverflow.com/questions/9214884/how-do-you-continuously-deploy-a-large-system-consisting-of-several-applications;NA;NA;;;At the moment we are deploying our whole application chain together and at once to production, because of the many dependencies that the systems have. And we have several Scrum teams, working on the same systems. With continuous deployment we would like to enable the team to self service a roll out to production, so business rolls out features when they want to, not based on an IT schedule. But how do we manage to roll-out changes (code, DB scripts) that are distributed over several code bases and find a strategy in order to deal with the dependencies between applications? What's the strategy to have scalable continuous deployment?

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.
