What Are CI CD and the CI CD Pipeline?

To improve the system, solutions like the Customer Advisory Board were introduced which is a form of manual approval. While this helped it wasn’t a full-proof solution because like mentioned earlier, humans are prone to error and inefficiencies which makes this process slow and dreary. Even if you see more or fewer phases in your organization’s pipeline, the concepts outlined will still apply. If you’re familiar with the Agile Methodology and the Scrum Methodology, you’ll have a better understanding of how to implement CDP as these strategies share related principles.

Continuous Delivery pipeline

Merged results pipeline—this is a type of merge request pipeline that treats changes from the source as though they are already merged into the target. Parent-child pipeline—a complex pipeline is broken down into a parent pipeline that triggers sub-pipelines . These all run with the same Secure Hash Algorithms in the same project, making it useful for monorepos. You would then only consult customers at the beginning and the end to see if the software met their needs. Everyone on the team can modify code, react to criticism, and solve problems as they arise.

Automated tests integrate with the pipeline

Because changes are deployed to the public automatically, this type of continuous deployment pipeline is typically used only by DevOps teams that have a proven process. Continuous testing is a technique where automated tests are integrated with the software delivery pipeline, and validate every change that flows through it. Tests execute in each phase of the pipeline to validate artifacts produced in that phase.

  • Businesses today need to update quickly and adapt quickly to changes, thus the engineering team requires a CI/CD process that can keep up with a quick-moving workflow.
  • A manual gate requires human intervention, and there could be scenarios in your organization that require manual gates in pipelines.
  • The use of Docker complicates CI/CD pipelines since each code build requires the creation and upload of a sizable container image.
  • But the bigger contributor to better code quality is smaller code changes.
  • As a result, rather than the quick change that businesses need, developers choose less frequent and more dangerous deployments.

Once the assembled system is certified, leave the assembly unchanged and promote it to production. We recommend against this composition anti-pattern where subsystems are composed into a system to be released as a whole. If you invest in independently deployable artifacts, you will be able to avoid this anti-pattern.


CI/CD workflows deliver the true value of agile, as code developed by different teams can be integrated and deployed in an incremental manner. Delivery/deployment—once the application is fully tested, it can continue to the CD stage. This could be the delivery of a prepared artifact or the automated deployment of your software . Continuous deployment requires a production environment you can deploy to (e.g. Kubernetes or a public cloud).

Additionally, SAFe’s DevOps Health Radar allows ARTs to quickly assess the performance of their delivery pipelines and identify specific DevOps practices that can be applied to optimize them. Validating on staging – Features that are ready for feedback get pulled into the validating on staging step to be integrated with the rest of the system in a staging environment, and then tested and validated. Once the current flow is understood, it can be mapped into the SAFe Continuous Delivery Pipeline.

Every check-in is followed as well as validated by an automated build and unit tests. In order to make sure that everything is working smooth and flawlessly, automated integration tests can be conducted. This is a repetitive process that takes place daily or can be done as per the need or the requirement of the project. Continuous delivery is an approach where teams release quality products frequently and predictably from source code repository to production in an automated fashion.

Some elements may be released daily—perhaps the web farm functionality. Other elements, like the hardware components of the satellite itself, may only be released every launch cycle. Several strategies to overcome continuous delivery adoption challenges have been reported. By bringing together the code and all of its prerequisites, we create a version of our product that can be deployed and shipped to customers. A program written in Java, C/C++, or Go must be compiled before it can be run, whereas programs written in Ruby, Python, or JavaScript do not require compilation. Infrastructure provisioning and deployment are part of the Continuous Delivery Pipeline, and they might be manual and involve numerous steps.


In the absence of CDP, software deployments are painful and stressful. Stakes are higher because the probability of things going wrong is increased and in the event of such, the consequences https://globalcloudteam.com/ are costly and time-consuming. It’s subsequently tested in an appropriate staging environment, which might include everything from cloud-based software to physical devices and simulators.

At Hewlett Packard Enterprise, we bring together the brightest minds to create breakthrough technology solutions that advance the way people live and work. Our people and our relentless dedication to helping our customers make their mark on the world. All working versions of the system are easily accessible to those responsible for quality assurance and product development. This means that developers can keep their attention on writing code and watching how it operates in production without having to worry about anything else.

The next step in the pipeline is continuous delivery , which puts the validated code changes made in continuous integration into select environments or code repositories, such as GitHub. Here, the operations team can deploy them to a live production environment. The software and APIs are tested, and errors are resolved through an automated process. In the final step of the CD process, the DevOps team receives a notification about the latest build, and they manually send it to the deploy stage. The difference between continuous delivery and continuous deployment is in the level of automation used in software or app releases.

Continuous Delivery pipeline

Since we have covered the fact that the CDP connects multiple stages, it only makes sense that different groups of people be involved in the collaboration and supervision of the entire process. So, if you want to make things work properly in your pipeline, everyone has to be dedicated to ensure its success. Now, this doesn’t mean that human intervention is completely eliminated from the pipeline. Even today in the digital era, many digital product companies still involve some form of human interaction in their pipelines for various reasons. With the ADAPT Methodology™, you’ll have all the knowledge and resources needed to equip you and your digital product company for success.

Benefits of Implementing CI/CD Pipeline

A CD pipeline delivers, as per business needs, quality products frequently and predictably from test to staging to production in an automated fashion. Throughout this stage, the new version of an application is rigorously tested to ensure that it meets all desired system qualities. It is important that all relevant aspects — whether functionality, security, performance or compliance — are verified by the pipeline.

Continuous Delivery pipeline

Although it is described sequentially, the pipeline isn’t strictly linear. Rather, it’s a learning cycle that allows teams to establish one or more hypotheses, build a solution to test each hypothesis, and learn from that work, as Figure 2 illustrates. Decoupling the web farm functionality from the physical launch eliminates the need for a monolithic release.

This step also includes looking at processing time and the quality of every step. This represents the percentage of work that the following step can work on without needing to repeat the task. This metric helps pinpoint the steps in a pipeline where poor quality might be happening and leading ci cd maturity model to lengthier lead times which translate to delays in value delivery. Don’t cut corners when it comes to this as the last thing you would want is to deliver sub-par products to your customers. The CDP provides the development team and everyone involved with an overview of changes and feedback.

By team size

The CI/CD pipeline is a continuous cycle of build, test, and deployment that provides continuous input for improvement. For example, developers may respond rapidly to criticism and improve the code when the code is tested. Finding and resolving defects late in the development process is costly and time-consuming. This is particularly true when problems arise with features already being launched in production. The team requires a way to integrate and validate its modifications since most current applications include writing code across several platforms and tools.

This includes addressing process time, as well as the quality of each step. The higher that number, the less rework is required, and the faster the work moves through the system. Continuous Exploration focuses on creating alignment on what needs to be built.

Developers on AWS

Just one phrase that is overlooked in the CI/CD tools can have a huge impact on the entire pipeline chain. The pipeline grows closer to being entirely automated the more accurate it is, going from continuous integration to continuous deployment without requiring any human intervention. With the speedier and more agile DevOps methodology, security is no longer handled until the production stage, as is the case with more traditional security approaches. To keep up with DevOps and avoid slowing down development speed, security tools must now integrate seamlessly into developer workflows and the CI/CD pipeline.

The CD pipeline is an agile and sustainable technique to produce software, similar to how a minimum viable product lowers risks and helps teams create something that better suits the demands of consumers. Since the software is integrated and built automatically, you can commit every small change. Imagine that you have hundreds of new features in your software, thousands of code lines changed in one release, and “something” goes wrong. You can use GitOps and declarative infrastructure to achieve closer parity between your pre-production and production environments by simply duplicating the configurations of the underlying clusters. Depending on the programming language and the integrated development environment , the build process can include various tools. The IDE may offer build capabilities or require integration with a separate tool.

Design for Failure in the Production Environment

Continuous testing is frequently implemented as a collection of automated regression, performance, and other tests run through the CI/CD pipeline. In Kubernetes, pull based deployment is done through a GitOps controller that detects discrepancies between the actual state and the desired state. If there are differences, it immediately updates the infrastructure to match the environment repository. It can also check an image registry to see if there is a new version of an image available to deploy. While the ideal pre-production environment is identical to the production environment, this is not always possible.

The Codefresh platform is a complete software supply chain to build, test, deliver, and manage software with integrations so teams can pick best-of-breed tools to support that supply chain. Pull based deployments have a major advantage over push based deployments—they make it very easy to undo changes to production environments to eliminate configuration drift. In any event of configuration drift, the GitOps controller automatically restores the application to the desired state. If a new deployment caused a problem, it is very easy to see what change caused the problem and revert to the last working configuration.
