What Is CI/CD? The CI/CD Definition

Development teams require a pipeline for delivering frequent and reliable changes to applications. The continuous integration and continuous delivery pipeline, or CI/CD tools, provides developers with the necessary implementation methods.

Continuous integration is a coding and management philosophy designed to permit the use of various tools and platforms while controlling repositories against changes. Primarily, CI provides consistency and automation into the building and testing of applications, allowing for more frequent and committed code changes.

Continuous delivery is another automation process that follows CI. Its responsibility is the automation of application delivery to specified infrastructure environments.

CI/CD is the natural progression of “quality at speed.” The pipeline allows for continuous testing and consistent delivery, including environment-specific parameters.

The Best CI/CD Pipeline Tools

With the transition toward DevOps and Agile culture to ensure application quality and accelerate deliveries, enterprises must rely on CI/CD tools. Unfortunately, it is challenging to pick among the ever-growing list of pipeline options, including AWS CI/CD and GitHub.

The CI/CD Best Practices

The DevOps movement pushes for efficiency, and it is precisely this philosophy that leads to the development of CI/CD tools. More and more companies realized the gap between development and IT resulted in costly problems and time-consuming remediation efforts in the later stages of the SDLC. By implementing specific practices throughout the SDLC, teams turn out quality work faster, which is crucial in the current technological environment.

However, teams must realize CI/CD pipelines are not stagnant processes; they are tools that require constant analysis and tweaking. When applying or defining a team’s CI/CD pipeline, there are several best practices to consider.

Build the CI/CD Pipelines Once

Many DevOps teams make the mistake of creating a new build at every stage. Unfortunately, when crews rebuild the software to suit different environments, they risk the introduction of inconsistencies, ultimately depleting confidence in previous tests.

It is best to use the same build artifact throughout the process, promoting it through the pipeline to the live release. Using this practice requires an environment-antagonistic build, meaning files, parameters, configurations, or scripts need to live through the deployment script rather than the build.

Using this technique, teams build once and gain confidence throughout the SDLC. While all elements should stem from the same source control system as the project, the build should reside in the artifact repository.

Monitor and Measure Your CI/CD Pipeline

The implementation of monitoring in a CI/CD pipeline is standard protocol, alerting development teams to any trouble as early as possible. While monitoring is OK, teams need to analyze data to improve pipeline design.

Looking into the analytics, team managers can determine the use of pipeline infrastructure. Comparing data like triggered builds per hour, day, or week, DevOps teams can learn when to scale the pipeline for greater efficiency.

Additionally, reviewing CI/CD information can alert teams to deployment delays or average speeds. Knowing how long projects are taking can provide insight into the need for performance optimizations and investments.

Finally, testing can let teams know when other strategies, such as parallelization, are necessary. It can also highlight focus areas for more tests.

Clean Your Environments

Between each deployment, pre-production environments need cleaning to make the most of testing. Long-running environments become cluttered with configuration changes and updates.

Environments diverge over time, meaning that pass-fail results from testing might return different results from the original setup. Beyond unreliable tests, cluttered environments come with hefty maintenance costs.

An easy way to manage environments is with containers. Developing, managing, and eliminating containers with each new deployment is doable, leading to consistent and scalable environments and dependable results.

Make It a Team Effort

The purpose of DevOps and the CI/CD pipeline is to break down the barriers between development, tests, and operations. Through CI/CD, teams are forced to collaborate and cooperate.

A successful pipeline requires input from all development and delivery disciplines. By using and acknowledging the expertise and talent from different working pools, teams can deal with potential problems as they arise, rather than leaving everything to the last minute, leading to production delays and expensive and time-consuming remediation efforts.

Collaboration creates a sense of shared responsibility, contributing to a sense of empowerment for individual team members. Additionally, it creates a culture of trust, leading to a better organizational culture.

CI/CD Benefits

The primary benefit of CI/CD is the ability to continuously integrate code into an access repository that is openly shared with the DevOps team. The collaboration expedites quality applications and software delivery because it streamlines testing, analysis, and mitigation. While the unification of several departments into one cohesive team creates efficiency, there are other CI/CD benefits as well:

  • Fault isolations
  • Smaller code changes
  • Greater test reliability
  • Accelerated Mean Time To Resolution
  • Reduced backlog
  • Faster release rate
  • Increased accountability and transparency
  • Reduced costs
  • Improved maintenance and updating methods
  • Greater end-user experience
