Explanation

AWS CodeDeploy is the correct answer because it specifically provides automated application deployments and rollbacks functionality.

Service Breakdown:

• AWS CodeDeploy: Automates application deployments to various compute services (EC2, Lambda, ECS) and provides automated rollback capabilities if deployments fail

• Amazon CodeGuru: A developer tool that uses machine learning to identify code quality issues and provide recommendations

• AWS CodePipeline: A continuous delivery service that orchestrates the entire release process but doesn't handle the actual deployment mechanics

• AWS CodeBuild: A fully managed continuous integration service that compiles source code, runs tests, and produces software packages

Key Features of AWS CodeDeploy:

• Automated application deployments
• Automatic rollback capabilities
• Deployment strategies (blue/green, canary, rolling)
• Health checks during deployments
• Integration with various AWS compute services

This service directly addresses the requirement for automated deployments and rollbacks in production environments.
