Continuous Delivery (CD) ensures:

Continuous Delivery (CD) ensures that software is always in a releasable state through automation. This practice emphasizes the importance of maintaining a codebase that is constantly ready for deployment to production at any given time. By utilizing automated testing, integration, and deployment processes, Continuous Delivery minimizes the risks typically associated with releasing new code. It allows for faster iterations and accommodates frequent updates, providing a structured pipeline from development to deployment, which significantly enhances the quality and reliability of software releases.

This approach contrasts with the notion of manual deployment processes, which can introduce delays and errors, as well as the idea that testing happens only after deployment, which can result in finding defects too late in the development cycle. Additionally, the requirement for integrating code once a month does not align with the principles of Continuous Delivery, which promotes more frequent and smaller releases to enable quick feedback and adjustments.
