Which Continuous Deployment activity ensures that changes operate correctly in production environments?

1. Monitor

2. Verify

3. Deploy

4. Respond

The correct answer is: Verify

The activity that ensures changes operate correctly in production environments is verification. This step is crucial because it provides the necessary checks to confirm that new features or fixes not only work as intended but also maintain the integrity of the existing system. Verification typically involves automated testing and other validation processes that are executed after deployment to catch any issues that may have been missed during earlier stages of development and testing. Monitoring is an ongoing activity that involves tracking the performance and health of the application after it has been deployed. While monitoring is important for identifying potential issues in real time, it does not directly ensure that the changes deployed operate correctly from the outset. Deployment refers to the process of moving changes into the production environment. However, this step alone does not guarantee that the newly deployed code functions as expected, necessitating a follow-up verification phase. Responding addresses how teams react to issues identified during monitoring and verification but is a reactive measure rather than a proactive assurance of quality and functionality in the initial deployment. In summary, verification plays a critical role in the continuous deployment pipeline, serving as a safeguard to ensure that all changes are functioning correctly before, during, and after their release.
