What is the main role and purpose of application deployment processes in the development system?

Application deployment processes ensure automated and controlled deployment of software in the production environment. Their main role is to guarantee that the new version of the application is installed correctly, without failures, and with minimal downtime. This includes environment preparation, file copying, configuration setup, database migration, and service startup.

Purpose of deployment processes:

• Automate routine tasks to reduce the likelihood of errors.
• Ensure repeatability and predictability of deployment.
• Rapid recovery in case of errors (rollback to previous version).
• Improve communication between development and operations teams.

Example: CI/CD pipeline that automatically deploys a new version of the application to servers after successful testing.
