LucidLink is a service which works in conjunction with the LucidLink app. 

The service coordinates and distributes metadata from your files stored in cloud (S3 compatible) object storage such as Amazon S3, Google, Alibaba, IBM, Wasabi, DigitalOcean etc. or on-premise solutions such as Zadara Storage, Cloudian, Minio, etc. The app inserts this metadata as a local file system within the OS.

Whatever data contained within the object store, in the global namespace, shows up “virtually” here as a locally stored file. When the application opens the file, the data from that file is streamed directly from the object storage (Bucket) to the device.
