What happens during the Setup lifecycle event in OpsWorks?

1. Instances are automatically scaled

2. Code is deployed to instances

3. Instances finish booting

4. Backups are created for instances

The correct answer is: Instances finish booting

During the Setup lifecycle event in AWS OpsWorks, instances finish booting. This phase is crucial because it signifies that the instance is fully operational and ready for further actions. After the operating system boots up and initial configurations are applied, the instance transitions into the Setup phase, where scripts defined in the OpsWorks stack can run, preparing the environment for any applications or services that need to be deployed. In this phase, essential tasks typically include installing software packages, configuring application settings, and integrating with other services. While the Setup event is important for ensuring that instances are prepared to run applications, it does not include deployment of code, automatic scaling, or backups, which occur either later in the lifecycle or in different contexts within OpsWorks. The clarity of this phase helps ensure a streamlined setup process, paving the way for subsequent actions like Deploy, which is responsible for delivering the application code to the instance.
