What is the difference between continuous delivery and continuous integration?

What is the difference between continuous delivery and continuous integration?

Continuous integration (CI) is the practice of frequently merging code changes into a central repository, while continuous delivery (CD) extends this by ensuring that the code is always in a deployable state, allowing for automated releases.

Can you explain how they work together?

Sure! CI focuses on automating the integration of code changes, while CD ensures that these changes can be deployed to production at any time, often using automated testing and deployment processes.

What are the benefits of using both?

Using both CI and CD improves code quality, reduces integration issues, and accelerates the release process, leading to faster delivery of features and fixes.

Are there any tools that support these practices?

Yes, popular tools for CI include Jenkins and Travis CI, while for CD, you might use tools like Spinnaker or AWS CodePipeline.

What challenges might teams face when implementing these?

Teams may face challenges such as cultural resistance, the need for proper tooling, and ensuring adequate testing practices are in place.
