In context of the tutorials, this application will be maintained as part of the project sockshop. Besides, the application will be deployed in three stages:

Dev stage: A developer can test the implementation of a new feature in this stage.
Staging stage: Performance test are conducted to verify the stability of the application.
Production stage: An end-user of the application will access the version deployed in this stage.
