An object storage maps a cloud object storage such as an AWS S3 bucket, an Azure Blob store or a GCP storage. Object storages can also be shared with anyone who has an account on RosettaHub or shared publicly via a URL.
Object storages can be auto-mounted as the working or reference volumes for RosettaHub Virtual Labs, Data Science Labs or Big Data and HPC labs. A native cloud object storage can be mapped by more than one object storage allowing for a fine grained access control.
