Server Export a directory structure with files that have information about Debian packages. This structure could have a meaning (architecture, version, license). Very huge repositories have the Debian packages in other repository, pool.

Server To split index files and Debian packages avoid to have replicated files in different directories, for example, documentation packages. Index files and Debian packages have to be accessed by web.
