In the context of AWS Elastic Beanstalk and the execution of commands defined in the "commands" section of an .ebextensions file, these commands are executed before the application and web server are set up. This allows users to run scripts or commands that may be needed to prepare the environment for the application and ensure that any necessary prerequisites are in place before the application itself is deployed.

Running commands at this early stage is particularly useful for installing dependencies, configuring the environment, or making any necessary adjustments to the Elastic Beanstalk instance that are critical for the deployment process. This phase occurs early in the lifecycle of the Elastic Beanstalk deployment process, allowing any modifications needed before the application code is extracted and run.

Commands in the "commands" section therefore facilitate a customized setup environment that aligns with specific application needs, ensuring that the necessary infrastructure is ready before the main deployment occurs.
