Which of the following features allows developers to release incomplete features while monitoring their effects?

The ability to release incomplete features while monitoring their effects is best described by dark launching. This practice involves deploying a feature to production that is not yet fully exposed to all users. The feature is essentially hidden or "dark" to users while still being monitored for performance, usage, and impact. This allows developers to gather insights, perform testing, and make necessary adjustments based on real-world use and feedback without affecting the broad user experience.

Dark launching is particularly beneficial in cloud environments where continuous integration and deployment practices are common. By enabling developers to monitor the performance and reliability of a feature under actual usage conditions, they can ensure that when the feature is eventually fully launched, it meets user needs effectively and efficiently.

Canary testing, blue-green deployment, and A/B testing serve related but distinct purposes. Canary testing involves releasing a new version of software to a small subset of users before rolling it out to everyone, but it does not specifically cater to incomplete features. Blue-green deployment focuses on minimizing downtime and reducing risk by running two identical production environments. A/B testing compares two variants of a feature to determine which performs better, often with already complete features. While these practices are valuable, they do not directly facilitate the release of incomplete features while monitoring their effects in the
