Deployment pipelines The DevOps engineer’s handbook

Helix Core provides full traceability on every change — including who, why, and what changed. Its ability to track and manage change supports compliance standards (including ISO 26262, PCI/DSS, and 21 CFR Part 11). Automation frees team members to focus on what they do best, yielding the best end products. Continuous deployment should be the goal of most companies that are not constrained by regulatory or other requirements. Donations to freeCodeCamp go toward our education initiatives, and help pay for servers, services, and staff.

Shipping code onto servers and having barriers is delivery, while Continuous Deployment is rapidly getting new features and bug fixes into the hands of your end-users. Whether it’s money or time , small problems expand exponentially when you double your size year over year, add new services, or more staff. Spending an hour building and deploying a service by hand can work when you have three services and deploy once a week. Move up to daily deployments for 10 services… well, you can do the math on that.

Ability to handover between team members smoothly

The technology stack for this pipeline is almost the same as for an infrastructure pipeline. At the same time, tools such as SonarQube, Semmle, Checkstyle or Lint software are usually used for coding this type of automation. It’s built on Argo for declarative continuous delivery, making modern software delivery possible at enterprise scale. The goal is to verify all assumptions made before development and ensure the success of your deployment. It also helps reduce the risk of errors that may affect end users, allowing you to fix bugs, integration problems, and data quality and coding issues before going live. For example, it’s not uncommon to have the CI phase fully automated but to leave out deployment as a manual operation to be performed by often a single person on the team.

The team needs to integrate a code for the tests to run automatically. One of the principles of GitOps is that deployment should be “pull based”. A traditional deployment process is “push based”, meaning that developers create a new version and directly deploy it to the live environment. Once you’ve established your SLOs, you can use them as a basis to automate test evaluation. One way to implement evaluation automation is to design quality gates – these are thresholds that determine the specific criteria for the software.

Don’t Mix Production and Non-Production Environments

When the build reaches the Deploy stage, the software is ready to be pushed to production. An automated deployment method is used if the code only needs minor changes. However, if the application has gone through a major overhaul, the build is first deployed to a production-like environment to monitor how the newly added code will behave. After gathering feedback and relevant information from users and stakeholders, the work is broken down into a list of tasks. By segmenting the project into smaller, manageable chunks, teams can deliver results faster, resolve issues on the spot, and adapt to sudden changes easier. In the early days of software development, developers had to wait for a long time to submit their code.

Your team can automate development, deployment, and testing with the aid of CI/CD tools. Some tools specialize in continuous testing or related tasks, while some manage the development and deployment and others manage the integration side. After your source code has successfully been built and passed all the relevant tests, it will either be automatically deployed to a runtime environment or released upon clicking a button. This is accomplished through a CI/CD (Continuous Integration/Continuous Delivery) pipeline.

Having a CI/CD pipeline in place brings many benefits not only to the product team but also to the organization’s business values. A rapid, accurate, and continuous feedback loop will effectively give shape to an organizational culture of learning and responsibility. When the release process gets streamlined in the CI/CD process, product updates are much less stressful for the development team. Therefore, having access to all versions of the system is crucial to QA as well as other stakeholders. Moreover, keeping the latest version updated will help improve the quality and reliability of QA feedback of bug logged. The surge of CI/CD trends over the past two years is prominent in the software product industry.

What is DevOps Pipeline & How to Build One

The purposes of each process are distinct, so don’t make the mistake of mixing and mashing. Instead, design your pipelines as components with modularity in mind, including concerns such as reuse and interoperability. You also need your workflows to be as smooth and efficient as possible. CISA has better aligned the CPGs with NIST’s Cybersecurity Framework, and added software supply chain goals. Maccherone said he also believes that testing should be done prior to the pull-request merge decision, which requires a container-based CI system that stands up the resources needed in the pipeline to run. Step one to great CI/CD security is to ensure that the infrastructure that backs the entire pipeline is properly configured, updated and isolated to prevent lateral movement.

  • If multiple developers are working on the same project, other team members usually manually review the new code before merging it with the master branch.
  • If a change to the pipeline causes problems, the person who made that change can get an alert, along with a link to that specific change.
  • An independent deployment is the process of deploying the compiled and tested artefacts onto development environments.
  • This is how your project can amass a mountain of technical debt in a hurry, and it will come back to haunt the project in the long run.
  • Plus, the CI/CD configuration needs to be stored as codes that allow reviewing, versioning, and restoring for future uses.

A software team working quickly can churn out great apps, but it’s often at the expense of security. This is especially true for teams working with an array of servers, services, and containers spread over multiple disparate systems. By making major decisions about the development process in advance, the team won’t have to break stride later on.


Since this cycle could go on and on, it enables developers to improve the initial code to the most optimized way possible. But, in fact, the build stage is not necessarily used for such languages as Python, JavaScript, and Ruby. Inability to pass the build phase indicates a basic project malfunction, which should be addressed as soon as possible.

Increasing the efficiency of the development pipeline makes happier customers and generates higher profits. Fortunately the automotive industry doesn’t work this way – and it shouldn’t look like this in software development either. One of the largest challenges faced by development teams using a CI/CD pipeline is adequately addressing security. It is critical that teams build in security without slowing down their integration and delivery cycles. Moving security testing to earlier in the life cycle is one of the most important steps to achieving this goal.

It enables to get the continuous improvement.

Developers and designers will no longer need to waste time switching between tools. Instead, they’ll be able to spend more time delivering value to your team. Brian Price, founder of Interplay, a security-focused managed service provider, agreed that software updates on CI/CD systems should be an especially big priority. In the fictitious automotive example at the start of this article, feedback came much too late and the individual parts were assembled only at the end. Implementing the right tools at the right time reduces overall DevSecOps friction, increases release velocity, and improves quality and efficiency. In an office setting, it will be up to the development manager to intercept any and all incoming requests that would otherwise reach the team and disrupt them.

It is also worth noting that developers using Google or AWS as a development platform can make use of their respective secrets management tools. They’re purpose-built to integrate with project development taking place on those platforms. That means they’re typically easy to integrate into workflows without much hassle. This was due to the frequent communication and collaboration breakdowns that occurred as a result of the siloes. In contrast, CI/CD pipelines are built on the integration and collaboration of these two teams, developers, and operators, which automates the entire workflow and rapidly accelerates the entire process.

Capabilities needed for Continuous Delivery

It allows developers to easily automate complex environments, using tools they are already familiar with. Development – this is where developers deploy the applications for experiments and tests. You must integrate these deployments with other parts of your system or application (e.g., the database). Development environment clusters usually have a limited number of quality gates, giving developers more control over cluster configurations. Since each build undergoes numerous tests and test cases, an efficient CI/CD pipeline employs automation.

With the right time to market, the product’s ROI will significantly increase. Can we help you build out pipelines and dominate the software delivery game? And you have different teams contributing across your software assembly line. Some of the most important practices in CI/CD have to do with security testing.

The continuous delivery aspect means incremental deliveries of software and updates to production. CD helps developers automate the whole software release operation and increase how frequently they release new features. This occurs after a developer has completed writing a new code addition and committed it to a source control repository such as GitHub. Once the commit has been made, the deployment pipeline is triggered and the code is automatically compiled, unit tested, analyzed, and run through installer creation.

Maintaining end-to-end observability for your dynamic continuous delivery pipelines is essential to allow DevOps teams to deliver successful applications. Monitoring allows you to ensure that your software continues to meet the criteria specified in your SLOs. Monitoring applications in production is essential to enable fast rollback and what is software development bug fixes. The idea is to ensure your deployment strategy accommodates unexpected faults and operates smoothly despite the issues, minimizing the impact on end-users. This stage is similar to what occurs in Independent Deployment, however, this is where code is made live for the user rather than a separate development environment.

For performance, most operating systems implementing pipes use pipe buffers, which allow the source process to provide more data than the destination process is currently able or willing to receive. Under most Unices and Unix-like operating systems, a special command is also available which implements a pipe buffer of potentially much larger and configurable size, typically called «buffer». This command can be useful if the destination process is significantly slower than the source process, but it is anyway desired that the source process can complete its task as soon as possible. E.g., if the source process consists of a command which reads an audio track from a CD and the destination process consists of a command which compresses the waveform audio data to a format like MP3. In this case, buffering the entire track in a pipe buffer would allow the CD drive to spin down more quickly, and enable the user to remove the CD from the drive before the encoding process has finished.
