Continuous Integration vs Continuous Delivery vs. Continuous Deployment

Output is generated in the form of big data or numerous documentation files. System errors such as “low memory” and “server not reachable” are addressed in this stage, bolstering the availability and security of the application. Once a CI/CD pipeline is successfully implemented in Jenkins, expand it by integrating test frameworks, external code repositories, and deployment strategies. Simply put, a strong culture of DevOps helps teams achieve common business goals instead of siloed departmental objectives. The communication gap and lack of cooperation among these equally-important teams are likely to lead to development challenges due to insufficient collaboration.

In this article, we will discuss what Continuous Integration and Continuous Deployment are, the differences between them, and why it matters. If hurdles stand between the code developers and putting out the production environment, application performance monitoring ci cd team members may inevitably be tempted to seek out the path of least resistance. Developers work in teams in order to produce code that will later be compiled and delivered in the form of staged releases to end-users.

3) The test stage covers automated testing and validates software behavior with an aim to prevent bugs from reaching users. This stage covers multiple types of testing, including functional testing and integration testing. The test tools commonly used in this stage include Appium, Selenium, PHPUnit, Jest, Playwright, and Puppeteer. Traditionally, integration is a costly activity that requires lots of back-and-forth among different engineering teams.

Continuous improvement is focused on making the entire CI/CD pipeline better, whereas continuous integration is focused on automating the build, test, and deployment process. This approach is especially relevant in continuous integration and continuous delivery, where the goal is to improve software more quickly and reliably. CI/CD is a set of practices that automate the process of building, testing, and deploying software.

Why You Need CI and CD for Successful DevOps

The common theme through these three continuous paradigms is a heavy reliance on automation and testing to drive the process. Ideally, a developer need only "press the button" to whisk a new build from the code repository through testing and on to delivery or deployment. This tantalizing proposition depends on the quality of the testing, the integrity of the automation behind it, and the careful attention of testers and software engineers. CD likewise relies heavily on tools and automation to take a build through advanced testing, including functional, user acceptance, configuration and load testing. These validate that the build meets requirements and is ready for use in a production environment. Again, small incremental iterations ensure that any problems revealed in testing are identified and remediated quickly and less expensively than traditional software development approaches.

A software solution may have many features, but some of them—or even just one of them—may be most critical to customers. Ultimately, the decision to use Continuous Integration, Continuous Deployment, or a combination of both depends on the needs of the software development team and the nature of the software being developed. By carefully considering the impact of each approach and balancing the tradeoffs involved, software development teams can deliver high-quality software quickly and efficiently. What is continuous integration (CI) and continuous deployment (CD)? Why has this method for delivering updates to software become the hallmark of advanced, modern software development methods using the DevOps method?

And in the context of security, only then—in our opinion—have you earned the right to call yourselves DevSecOps. CircleCI is created to power a Bitbucket or GitHub CI/CD pipeline. Developed and maintained by Facebook (now Meta), it is a good example of a sturdy CI/CD pipeline.

What is the difference between CI and CD

Let's examine a typical CI/CD pipeline, consider the activities within each stage and note several possible tools to tackle them. Under Continuous Integration, teams don’t need to worry about packaging huge commits and releasing profound structural changes. Instead, they can engage in smaller, iterative changes that are less likely to be disruptive.

There is no single methodology that teams should choose for CI/CD; no option is one-size-fits-all. Ask internal clients which work styles makes sense for joint teams and that best suit the portfolio and assets. Try different approaches until teams find what works best for them. CI/CD and DevOps, their differences and how they function together are frequently misunderstood. With DevSecOps gaining traction, a future-proof CI/CD pipeline has checks in place for code and permissions, and provides a virtual paper trail for auditing failures, security breaches, non-compliance events. DevOps is a combination of 3C's - continuous, communication, collaboration and this lead to prime focus in various industries.

It entails the automatic deployment of all code updates during the testing and production stage. Although it’s important to understand the differences between CI vs. CD, most organizations need both. CI is easier to achieve than CD and can be standalone; some developers still use their integrated development environment (IDE) and hand-coded Bash scripts for software delivery.

Challenges of managing CI/CD pipelines

But even if your tech stack doesn’t have such a tool, developers can be encouraged to commit code to the repository as often as it makes sense for them to do so. The more frequently code can be integrated into the pipeline, the more quickly the iterative cycle can self-improve, leading to faster product releases. Agile practices, when integrated with automated testing and continuous feedback, accelerate development and ensure the swift detection and management of bugs.

What is the difference between CI and CD

Another difference between the two is the level of automation involved. CI relies heavily on automated testing tools, which run tests automatically after each code change. This approach helps to ensure that code changes do not break existing functionality and maintain the stability of the software. CD takes automation to the next level by automatically deploying code changes to production as soon as they are ready. DevOps, short for development and operations, is a collaborative methodology meant to break down the barrier between development and operations teams in an organization. It’s simply because many organizations and development teams conflate the two with the effect that they focus on continuous integration only, thinking that they’re also practicing continuous delivery.


While continuous integration optimizes building, integrating, and testing code within a development environment, continuous delivery deals with effective production deployment. Globally, development teams rely on CI/CD practices to deliver code changes rapidly and reliably. On the other hand, DevOps principles drive development and operations teams to work together with an aim to streamline all aspects of product development. CI/CD is the combined practices of continuous integration (CI) with continuous delivery or continuous deployment (CD). The purpose of CI/CD is to allow development teams to deliver code changes more frequently and reliably. While continuous delivery is an extension of continuous integration, deployment builds on top of delivery.

  • Continuous Integration and Continuous Deployment are two essential concepts in modern software development.
  • With Continuous Delivery, a developer can ideally release a commit and soon see it in a deployable state.
  • This process ensures complete development of the product and thoroughly prepares it for deployment.
  • CD takes automation to the next level by automatically deploying code changes to production as soon as they are ready.
  • It is crucial to understand the problems CI and CD solve to use them properly.
