Which description of a canary deployment is true?

Canary deployment is a deliberate, controlled strategy, not an accidental deployment.

While canary deployments can be rolled back, the 'automatic rollback after a configurable amount of minutes' describes a specific feature often used *with* deployments, not the definition of a canary deployment itself.

Canary deployment is a release strategy for software, unrelated to data mining development.

A canary deployment strategy involves releasing a new version of an application to a small, controlled group of users or servers first. This allows for monitoring the new version's performance and stability with minimal impact, and if issues arise, the impact is contained, making it safer to roll out changes.
