B. Immutable: In an immutable deployment, AWS Elastic Beanstalk deploys the application version to a fresh group of instances in a new Auto Scaling group. Once the new instances pass health checks, they are moved to the existing Auto Scaling group, and the old instances are terminated. This approach ensures that new instances are used for the deployment, minimizing the impact on the existing environment. D. Blue/Green: Blue/green deployment involves deploying the new version of the application to a separate environment (the "green" environment). Once the new environment is ready and tested, the traffic is switched from the old environment (the "blue" environment) to the new one. This type of deployment is effective for ensuring that the new version is deployed on new instances and provides a straightforward way to rollback if needed.

Why BD? As Blue/Green is related to CodeDeploy, must not it be BE?

correct options : B and D

Immutable: An immutable deployment launches a full set of new instances running the updated version of the application alongside the existing instances. It ensures that the old instances remain untouched until the new ones pass health checks. Once validated, the old instances are terminated, resulting in minimal downtime. Rolling with additional batch: In a rolling deployment with an additional batch, Elastic Beanstalk launches a new batch of instances before taking any existing instances out of service. This maintains full capacity during deployments. After successful deployment, the additional batch of instances is terminated.

BD is the correct answer.
