He refers to jez humble’s post on continuous delivery vs continous deployment and adds: Essentially, it is the practice of releasing every good build to users” , explains jez humble, author of continuous delivery.

Once you have the build ready, cd comes into the picture and follow another set of steps. As martin fowler puts it, “a business sponsor could request that the current development version of the software be deployed into production at a moment’s notice—and nobody would bat an eyelid, let alone panic.” at its core, continuous delivery follows a streamlined process commonly known as the continuous delivery pipeline.

Satisfying customers feedback on the production is important.

This is in contrast to continuous deployment which uses automated deployments. Continuous delivery builds on this, dealing with the final stages required for production deployment. Designing and operating large distributed systems, volume 2;

Is your software always deployable throughout its lifecycle? Ci and cd are two acronyms frequently used in modern development practices and devops.ci stands for continuous integration, a fundamental devops best practice where developers frequently merge code changes into a central repository where automated builds and tests run. The principal benefits of continuous delivery are:

Continuous delivery is the ability to deliver software that can be deployed at any time through manual releases; Continuous deployment at my current client, we've been overhauling our ci process to enable us to work towards continuous deployment.

Your application is always ready to deploy to production through a largely automated process. — martin fowler, chief scientist, thoughtworks. After short exploration of some of the tools used today, we'll move towards the flow (from setting up brand new environment and getting the code from the repository to the creation of fully tested and verified distribution).
