Continuous Integration and Delivery
Continuous Integration and Delivery (CI/CD) is a software development practice where code changes are automatically built, tested, and prepared for release to production. CI involves regularly merging code into a shared repository, triggering automated tests to detect errors early. CD extends this by automating the deployment process, ensuring that software can be reliably and quickly released at any time. Together, CI/CD improves software quality, accelerates development cycles, and reduces manual intervention.

💡 Key Takeaways
- Understand how CI automatically builds and tests code changes when they are merged into a shared repository to catch errors early.
- Explain how CD automates the release process to make deployments more reliable and repeatable.
- Identify the common stages of a CI/CD pipeline: commit, build, test, review, and deploy to staging or production.
- Differentiate between continuous delivery and continuous deployment and when each approach is appropriate.
- Recognize the benefits and requirements of CI/CD, including faster feedback, higher quality code, and the need for test automation and environment parity.
❓ Frequently Asked Questions
What is Continuous Integration (CI)?
A practice where developers frequently merge code into a shared repository, triggering automated builds and tests to detect errors early.
What is Continuous Delivery/Deployment (CD)?
A set of practices that automatically builds, tests, and prepares code for release, and often deploys to staging or production, enabling rapid and reliable releases.
How does a CI/CD pipeline typically work?
Code changes are pushed, an automated build runs, tests and quality checks execute, artifacts are created, and deployment steps move the release to the next environment with configured gates.
What are common benefits of CI/CD?
Faster, more reliable releases; earlier bug detection; higher code quality; and reduced manual deployment effort.
