Historically, GitLab supported storing files that could be accessed from multiple application
shared/, using a shared storage solution like NFS. Although this is still an option for
some GitLab installations, it must not be the only file storage option for a given feature. This is
because cloud-native GitLab installations do not support it.
Our uploads documentation describes how to handle file storage in such a way that it supports both options: direct disk access and object storage.
