What characterizes continuous deployment?

• A. Manual deployment after code review
• B. Automatic building, testing, and deployment of code changes
• C. Frequent updates without a testing phase
• D. Integration of code changes every week

Answer: (B)

Continuous deployment is characterized by the automatic building, testing, and deployment of code changes. This process allows for code changes to be released to production environments as soon as they pass automated tests. The key feature of continuous deployment is its automation, which enables teams to deliver new features, bug fixes, and other changes rapidly and reliably.

The emphasis on automation helps streamline the development process, reducing the risk of human error associated with manual deployments. Additionally, because the deployment happens automatically after passing tests, it promotes a culture of rapid iteration and feedback, allowing teams to respond quickly to user needs and issues that arise.

Options discussing manual deployment after code review or frequent updates without a testing phase do not align with the principles of continuous deployment, as they imply either a slower process or a lack of quality assurance that is integral to the practice. Option about integrating code changes every week doesn’t capture the essence of continuous deployment, which emphasizes ongoing and immediate deployment rather than periodic updates.
