Answer Description

A canary deployment strategy involves rolling out changes to a small subset of users to test the impact before deploying it to the entire infrastructure. This minimizes the risk as it allows for monitoring and quick rollback if necessary. Blue/green deployment involves switching traffic between two identical environments that only differ in the version of the application they are running. Rolling updates incrementally replace the previous version with a new version across all hosts. Resume-based deployment is not a recognized AWS deployment strategy.
