Continuous Delivery And Maturity Model

Currently, the CD Maturity Model data is stored in the js/data/data_radar.js file, as an array of JavaScript object literals. It would be very easy to convert the project to use a data source, such as a static JSON or YAML file, or MongoDB database. The application is a browser-based tool, which uses the D3.js JavaScript library. Infrastructure as a code which speeds cycle time by using code to define and customize infrastructure and configurations needed for different scenarios. Pipeline as a code which applies CI/CD best practices to job configurations. Proven implementation models and frameworks to accelerate time to market.

There’s no human intervention, and only a failed test will prevent a new change to be deployed to production. A continuous delivery approach requires the production and test environments to be similar. Once new code is committed, it triggers an automated work flow that builds, tests and stages the update.

Continuous Deployment

The DevOps methodology addresses organizational issues related to the software production process. Since it comes directly from the agile movement, it promotes incremental, iterative solution delivery. DevOps is not about a dedicated team nor is it governed by a well-defned set of rules or tools. The first is explain the value of test implementation and process automation to the business so that this work can be prioritised with new features etc…. To me much of the value is about stability, reliability, and efficiency of delivery.

Other processes in the company need to keep up with the rapid pace of deployments. Make feature flags central to your deployments so that your company can easily co-ordinate new requests. Increases the number of releases and features that you can deliver.

With an automated pipeline, development teams improve both the velocity of releases as well as the quality of the code. New features, improvements and fixes are added continuously in small increments resulting in a product with fewer defects, allowing you to be more competitive. Some teams use the term “continuous delivery” interchangeably with the similar DevOps term “continuous deployment.” The difference between the two terms is subtle but important. Continuous delivery means that the updated code base is available to move onto the next development stage, whether that be staging, user review, or production.

  • DevOps is less about forming yet another silo and is more about adopting a new philosophical approach to software development.
  • Customers see a continuous stream of improvements, and quality increases every day, instead of every month, quarter or year.
  • An integration server to manage the tests and to integrate with the code base.
  • If you’re just getting started on a new project with no users yet, it might be easy for you to deploy every commit to production.

They found that cycle time, deployment frequency, change failure rate and mean time to recovery are closely related and correlate with other beneficial metrics like delivery success and profitability. We know our work isn’t done until it’s in production and much like Continuous Integration we become safer, faster and better when we ship smaller releases more often. A Continuous Delivery pipeline involves a number of stages — coding, commiting the code to source control, unit testing and integration, building and then deployment to production. Between each of these stages, code typically goes through many different suites of automated tests before the new feature lands in production. Reduce your time to market from weeks and months to days or hours.


If we are confident in our processes when we press the big red button, then we are good to go. We don’t have organizational cultures that support frequent delivery. When we come to this situation this challenge can rightly make you scared.

Companies that successfully implement Continuous Delivery solutions can gain big advantages over their competition. Those that don’t can be hampered by higher operational costs, slower cycle times, fewer satisfied customers, and declining revenues and profits. After the issues are resolved efficiently, it becomes easy to build the release.

What Are Continuous Integration

Continuous Delivery is the ability to ship working software to production at any point. We believe that the only way to categorically prove software is production ready is to deploy it to production. Automated testing and pre-production environments can increase your confidence, but they can never account for everything that can possibly go wrong. CI/CD relies on automation to speed the processes of development, deployment, and testing. Automation can also support security as part of a DevSecOps strategy. DevOps describes approaches to speeding up the processes by which an idea goes from development to deployment in a production environment where it can provide value to the user.

Others do branch-based development when individually developers will have their own branches, or teams will have branches for different features. We described a barebones template for an end-to-end production pipeline for ML systems. Creating additional workflows and pipelines can be useful in cases where roles would like separation of concerns.


In order to convince everyone of the value of Continuous Delivery, we rolled out the new release process slowly. We started with lower profile, less risky systems using Google App Engine which made deploying frequently much easier. Once we had this in place, we made sure to make the most of it. We deployed frequently and sought opportunities to provide small features or fixes rapidly. This meant that users became advocates for Continuous Delivery, asking why other software couldn’t be delivered in the same way. Having a single feature released at a time makes identifying the source of a problem much quicker and the decision over whether or not to rollback much simpler.

Pieces are added on in each increment, and those increments may be small or large. A great illustration of the difference between Incremental and Iterative development is Jeff Paton’s Mona Lisa. The CI server will tell a developer if their latest code builds were successful and if they continue to pass tests. To be considered to be practising CI, Steve and Annie must check-in to the main source repository, integrate and test their code frequently and often.

There is absolutely no way other than any failure in the test that may stop the deployment of new changes to the output. This step is a great way to speed up the feedback loop with customers and is free from human intervention. Most organizations today have implemented some form of CI/CD to automate stages of development. Having a CI/CD branching strategy can help your teams integrate code easier and find bugs before they are released into production.

A Look At How Continuous Integration Works

We’re the world’s leading provider of enterprise open source solutions—including Linux, cloud, container, and Kubernetes. We deliver hardened solutions that make it easier for enterprises to work across platforms and environments, from the core datacenter to the network edge. Continuous delivery makes up part of CI/CD, a method to frequently deliver software by automating some of the stages of app development.

Browse By Team Type

When a feature flag is turned on, it effectively hides it from the rest of the build. This allows the rest of the development team to release other complete features, without holding up a deployment or affecting customers in production. Suzie Prince is Head of Product for ThoughtWorks Studios building pioneering tools for software development teams. She has over ten years experience as a business analyst and product manager designing and delivering software that is valuable, usable, feasible, and desirable.

How you recruit and retain talented individuals is largely a question of how you sculpt their experience — namely, with modern software delivery tooling. Often changes made to data sets have effects on the data scientists who create the ML models and how ML engineers integrate with changes. Below continuous delivery maturity model is an illustration of the common functional silo that tends to emerge. Continuous Delivery-as-a-Service including pipeline analysis/design-architecture; plugins/modules discovery/adoption; and CD tool, integration and testing. A fully-equipped delivery platform including cloud-based Test/QA Labs.

This is a set of stages that Steve and Annie’s code changes go through before they are done and ready to be delivered to production. Commonly these will be “build”, “unit test”, “functional tests”, “performance test” and “deploy”. Only once the code goes through the entire deployment pipeline can the software be delivered to production. This is a practice where every change that Steve or Annie makes, and which passes all the test stages,automatically goes to production.

The most important thing to understand about the role continuous delivery plays in DevOps is that “delivery” does not mean “pushed into production.” This test is essential if you want to ensure that the deployment was successful, and in particular to test that your configuration settings for the production environment are set up correctly. In my ideal world the ops people would be at the standup because they are essential to delivering the work to production and are part of the team. However, as change begins at organisations I have seen it where Dev and Ops teams met to discuss work separately before moving to the one team model.

Continuous Integration Overview

The amendments by the developers are validated by creating a built and running an automated test against them. Defining what to monitor and what to be alerted on will be done by developers by checking and monitoring configuration files into version control systems along with applications source code. With each “Commit” or “Pull Request” code gets built, deployed and automatically monitored with dashboards, tagging and alerting rules.

This approach allows SRE teams to establish guardrails and standards while allowing Dev teams to have the flexibility to control the specific settings using their know-how. To put it simply continuous integration is part of both continuous delivery and continuous deployment. And continuous deployment is like continuous delivery, except that releases happen automatically.

It is unreasonable to expect people with busy day jobs to use pre-production tools in a way that even closely resembles real use. Small groups of user testers for a website are never a substitute for a global audience. Continuous deployment is an excellent way to accelerate the feedback loop with your customers and take pressure off the team as there isn’t a “release day” anymore. Developers can focus on building software, and they see their work go live minutes after they’ve finished working on it.
