Continuous Delivery and Maturity Model DevOps ~ Ahmed AbouZaid!

At beginner level, the monolithic structure of the system is addressed by splitting the system into modules. Modules give a better structure for development, build and deployment but are typically not individually releasable like components.

Optimizer combines related scripts together into build layers and minifies them via UglifyJS . Imagine that a developer makes a change in the code after this happens you need to promote the code to the integration environments, send notifications to your team members and run the testing plan. It facilitates the merging of a new code into the main code base. The idea allows one to run various types of tests at each stage and complete it by launching with the deployment of the system in the actual product that end-users see. Continuous Delivery allows automating the entire software release process. The goal is to create a trustworthy and automated process that delivers software from the developer to the user.

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. In your path to provision automation and hands-free infrastructure, make sure you have a clear path to the Ops part of your DevOps team or organization, making sure to avoid bottlenecks when infrastructure just needs a magic touch of the hand. One way of accomplishing that is to have a separate stream or category of issues assigned to the DevOps teams in charge of infrastructure provisioning. Continuous Delivery presents a compelling vision of builds that are automatically deployed and tested until ready for production. The list is quite intimidating so we’ve highlighted the practices we think you should focus on when starting on this journey. The high priority practices were chosen because they give the most impact in terms of productivity, quality, delivery and risk mitigation.

At this level reporting is typically done manually and on-demand by individuals. Interesting metrics can e.g. be cycle-time, delivery time, number of releases, number of emergency fixes, number of incidents, number of features per release, bugs found during integration test etc. At this stage it might also become necessary to scale out the build to multiple machines for parallel processing and for specific target environments. Techniques for zero downtime deploys can be important to include in the automated process to gain better flexibility and to reduce risk and cost when releasing. At this level you might also explore techniques to automate the trailing part of more complex database changes and database migrations to completely avoid manual routines for database updates. A typical organization will have one or more legacy systems of monolithic nature in terms of development, build and release. Many organizations at the base maturity level will have a diversified technology stack but have started to consolidate the choice of technology and platform, this is important to get best value from the effort spent on automation.

Why a maturity model?

As a distributed revision control system it is aimed at speed, data integrity, and support for distributed, non-linear workflows. All changes (code, configuration, environments, etc.) triggers the feedback mechanisms. Optimised for rapid feedback and visualisation of integration problems.

  • However it is the logical conclusion of Continuous Delivery where the release to production is completely automated.
  • Tagging and versioning of builds is structured but manual and the deployment process is gradually beginning to be more standardized with documentation, scripts and tools.
  • At beginner level, the monolithic structure of the system is addressed by splitting the system into modules.
  • To do that, they need visibility of how the software performs in production and for the rest of the organization to be bought into the approach.
  • After a quick review of “Continuous integration tools and best practices”, I also did read more about “Continuous Delivery “, and I found some great articles about it that worth to read by every sysadmin, developer, and DevOps.
  • The model also defines five categories that represent the key aspects to consider when implementing Continuous Delivery.

Here is another attempt to the maturity model that picks the best pieces from each of those. Schedule a demo with one of our specialists and start improving your devops practices.

A detailed explanation of what each level of GitOps maturity looks like in practice. Using this, you can identify which level your organization falls into.

Several Continuous Delivery Maturity Models are available, such as InfoQ, UrbanCode, ThoughtWorks, Bekk, and others. Deploying is the core of how you release your application changes. In this blog post, we will be exposing maturity level checklists for different DevOps areas so you have an idea where you at in terms of Continuous Delivery. Maintain a proper level of coordination between CI and CD. Fast and high-quality results from the application of the technique are possible only after a long and thorough adjustment of the interaction between all the parties involved. Chooses technology stack based on what is best for each purpose. Database migration and rollback is automated and tested for each deploy.

Commonly each person integrates at least once per day giving place to several integrations during the day. Each integration should be verified by an automated Build Verification Test . These automated tests can detect errors just in time so they can be fixed before they create more problems in the future. This helps to reduce a lot of integration issues since this practice allows to develop faster and in a more efficient way. The speed of introducing new functionality – from a client request to delivery. CI/CD allows us to run updates in a matter of days or weeks compared to a whole calendar year with the classic waterfall approach.

What is continuous delivery maturity model?

NISI has recently released the Continuous Delivery 3.0 maturity model, or CD3M. The Maturity Model guides the improvements of Continuous Delivery pipelines and/or software development processes in software organizations. The CD3M maturity model has five levels from Foundation level (1) towards Expert level (5).
