Continuous delivery is a software development practice where software can be released to production at any time by building software in a way that enables frequent, automated releases. It involves practices like continuous integration, where code is automatically merged and tested frequently, automated testing and deployment, and using deployment pipelines and tools to streamline the release process. Many large tech companies practice continuous delivery, with some deploying new code in minutes or every 11 seconds to get changes to users quickly.

13. Continuous Integration
“Continuous integration (CI) is the practice, in software
engineering, of merging all developer working copies to a shared
mainline several times a day.”
