Difference between CI and SI

Would you like to learn about CI and SI? This article will provide a comprehensive overview of Continuous Integration (CI) and Continuous Delivery / Continuous Deployment (SI) concepts, their examples, uses, and differences.

What is Continuous Integration (CI)?

Continuous Integration (CI) is a software development practice where changes made by developers are frequently merged into a shared repository. The changes are then automatically verified by building and running automated tests to detect integration errors as early as possible.

Examples of CI:

  • Automated builds triggered by code commits
  • Running unit tests after each code change
  • Code reviews before merging changes

Uses of CI:

The primary purpose of CI is to ensure that changes made by developers do not introduce integration issues. It promotes early detection of bugs, reduces the risk of merging conflicting changes, and speeds up the development feedback loop.

What is Continuous Delivery / Continuous Deployment (SI)?

Continuous Delivery (CD) and Continuous Deployment (CI) are practices that extend CI by automating the release process. CD focuses on automating the delivery of software to a production-like environment, while CI/CD pipelines automate the deployment of software changes to production environments.

Examples of CI/CD:

  • Automated build and deployment pipeline
  • Automated testing in different environments
  • Deployment to staging and production environments

Uses of CI/CD:

CI/CD enables faster and more reliable software releases. It ensures that software changes are thoroughly tested in a production-like environment and makes it easier to reproduce and fix issues. This practice improves the overall quality and stability of the software.

Differences between CI and SI:

Difference Area CI SI
Process Focuses on integrating code changes frequently into a shared repository and running automated tests. Extends CI by automating the delivery and deployment processes.
Scope Primarily focuses on integrating code changes regularly and detecting integration issues. Includes integrating code changes, automating the release process, and deploying software to production environments.
Objectives To detect integration issues early, reduce conflicts, and provide faster feedback to developers. To automate the software delivery and deployment process, enabling faster and more reliable releases.
Automation Usually involves automated build, test, and code review processes triggered by code commits. In addition to CI automation, involves automating build, testing, and deployment to different environments.
Release Timing CI can be triggered on each code commit, providing frequent feedback to developers. SI can be triggered after successful CI completion or at specific intervals, aiming for release readiness.
Environment CI focuses on ensuring code changes integrate well in a shared repository. SI focuses on deploying software to production-like or production environments.
Testing CI typically includes unit tests and integration tests to ensure code quality. SI often involves testing the software in multiple environments to ensure compatibility and reliability.
Feedback CI provides developers with quick feedback on integration errors and potential conflicts. SI provides feedback on the readiness of the software for deployment and potential issues in different environments.
Deployment Frequency CI focuses on integrating code changes frequently but does not determine the deployment frequency. SI automates the deployment process and enables frequent or continuous deployments, depending on the organization’s needs.
Team Collaboration CI encourages collaboration between developers by synchronizing code changes and detecting conflicts early. SI enhances collaboration by creating a shared understanding of the release process and ensuring smoother deployments.


In summary, Continuous Integration (CI) is focused on integrating code changes frequently and verifying them using automated tests, while Continuous Delivery / Continuous Deployment (SI) extends CI by automating the software release and deployment processes. CI ensures early detection of integration issues, while SI enables faster, more reliable, and frequent software releases.
