What is the main function of the 'Cartridge' in SFCC?

The main function of the 'Cartridge' in Salesforce Commerce Cloud (SFCC) is to package and deploy functionality. Cartridges are essentially modular components that contain various types of code, such as scripts, templates, and business logic, which can add or extend the capabilities of a storefront. They enable developers to organize code efficiently, allowing for easier maintenance and updates.

By utilizing cartridges, development teams can create isolated units of functionality that can be reused across multiple projects or environments, enhancing scalability and flexibility. This modular approach facilitates version control and deployment processes, making it simpler to update or roll back features as needed.

The other choices, while related to functionalities you might manage within an SFCC environment, do not accurately represent the primary purpose of cartridges. For example, creating database backups, archiving products, and setting user permissions are essential tasks, but they are not directly associated with the cartridge concept in SFCC.
