What is CI/CD?

Illustration of IT items with focus on a question mark

Overview

Continuous integration (CI) and continuous delivery (CD) are two essential components of both agile and DevOps toolchains that lead to successful software development. CI/CD helps ensure that code is always in a releasable state and that new features and bug fixes reach customers as quickly as possible.

CI/CD

What is CI/CD and how does it work?

Continuous integration is the practice of merging all code changes into a shared mainline several times a day during the build or integration stage of development. As developers merge their code changes, they can run automated tests to detect and fix errors quickly. This enables them to improve software quality and minimize the time it takes to verify and deliver updates. CI primarily prevents integration challenges that can occur when developers do not merge code changes for long periods.

Continuous delivery is an expansion of CI in which developers automatically deploy code changes into a testing or staging environment post-build. This process ensures development and operations teams have software artifacts that have passed through standardized, continuous testing and are ready for deployment after the build stage. With CD, teams can automatically test and deploy code changes quickly and always ensure a production-ready codebase.

What are the principles of CI/CD?

In every CI/CD campaign, there are four main principles:

  1. Automate everything: The more you can automate, the less manual work is necessary and the faster your team can deliver new features and bug fixes.
  2. Build in quality: Developers should build quality into the software from the start rather than as an afterthought. This means writing automated tests and performing code reviews as part of the development process.
  3. Test early and often: By testing early and often, development and operations teams can source errors quickly and prevent them from integrating into the codebase.
  4. Deploy frequently: The more regularly you deploy, the less risk there is with each deployment. This also enables customers to receive new features and bug fixes faster.

The benefits of CI/CD

There are several benefits to using CI/CD in your software development projects, including:

  • Faster delivery of new features and bug fixes
  • Improved software quality
  • Reduced risk
  • Improved collaboration

Faster delivery of new features and bug fixes

By incorporating testing and OpenText™ Software Delivery Management with CI/CD, you can deliver new code changes to customers faster. This means that they will get new features and bug fixes sooner, and you'll be able to respond to customer feedback more quickly. Overall, faster delivery times associated with CI/CD enable a shorter time to market, less development pressure, and satisfied customers—all of which enhance an organization’s unique value proposition (UVP) and competitive edge.

Improved software quality

By testing early and often with CI/CD, you can find errors quickly and prevent them from entering the codebase. This leads to fewer bugs in production and ensures software is performing and behaving correctly before getting into the customer’s hands.

Reduced risk

Deploying code changes frequently reduces the risk of each deployment. This is because there is less code to deploy and test with each deployment. Additionally, if a problem occurs, it will be easier to identify and fix it quickly and efficiently.

By embedding application security testing directly into the CI/CD pipeline, organizations can catch and remediate vulnerabilities earlier in the software development lifecycle. This shift-left approach significantly reduces the risk of releasing exploitable code—helping teams achieve compliance, reduce rework, and deliver secure applications at speed.

Improved collaboration

When a developer alters a branch of code in isolation, there’s a high chance that their code changes will conflict with changes other developers are making simultaneously—which could result in a broken app. With CI/CD, however, developers can merge all code changes into one central mainline in real-time and validate them through automated testing. If there’s a conflict between updated and existing code, CI/CD makes it easier to source and mitigate that conflict before the software reaches the end-user.

How does CI/CD work?

There are four main steps in building a CI/CD pipeline:

  1. Build: Store and package source code into an executable artifact.
  2. Test: Insert artifact into an automated testing environment to validate code accuracy and behavior.
  3. Deploy: Deploy artifact into a testing or staging environment (for development and operations teams) and a production environment (for end-users).
  4. Monitor: Monitor application for errors and performance issues in deployment environments before an official release.

These four steps are typically repeated during code changes, ensuring that new code functions appropriately and successfully integrates into the codebase without breaking an app.

Why do you need a CI/CD pipeline?

A CI/CD pipeline is essential for any software development or operations team that wants to automate the DevOps process. Using a CI/CD pipeline, developers can build software artifacts, run automated tests, and quickly source and mitigate errors within code. Additionally, developers can get bug-free code updates or new features into customers’ hands through OpenText™ Software Delivery Management.

OpenText can help with CI/CD

If you’re searching for a CI/CD tool that can streamline your CI/CD pipeline, OpenText Software Delivery Management can help. OpenText equipped OpenText Software Delivery Management with features that enable centralized and efficient software development planning, test management, release management, project traceability, and deep analytics. OpenText Software Delivery Management can help with your CI/CD pipeline in two primary ways:

  1. It can help you automate the testing process by running tests automatically whenever code changes happen.
  2. It provides a unified platform for managing your software development artifacts, including code changes, tests, and builds. This makes it easy to track everything happening in your project and quickly identify problems.

If you're looking for a CI/CD solution that can help improve the quality of your software and speed up the delivery of new features in the cloud, OpenText Core Software Delivery Platform is an excellent option. OpenText Core Software Delivery Platform, a value stream management and DevOps platform, can help you build, test, and deliver faster without replacing the tools that are working for you.

How OpenText helps with CI/CD security

OpenText Application Security is a comprehensive, developer-friendly application security-as-a-service solution that fits into your CI/CD workflows, and helps development and security teams work together to release secure software faster and with greater confidence. Security becomes part of the process, not a blocker.

Whether you are building cloud-native applications or working with legacy systems, OpenText supports automated and continuous security testing throughout the software delivery process. With integrations into tools like Jenkins, GitHub Actions, Azure DevOps, and GitLab, you can enforce security policies, fail insecure builds, and prioritize critical issues before code reaches production.

Our solution supports static application security testing (SAST), dynamic application security testing (DAST), and software composition analysis (SCA)—all built for DevSecOps teams. Its key benefits include:
