Hybrid File Transfer Solution¶
Overview¶
The Hybrid File Transfer Solution enables secure, bidirectional file exchange between on-premises laboratory systems and external partners. It bridges an on-premises file share with cloud object storage, and exposes a managed SFTP endpoint so external collaborators can exchange files without requiring direct network access into the internal environment.
In summary, the solution provides for:
- Laboratory metadata generated on-premises to be made available to authorized external partners.
- External partners to submit files that internal laboratory users can consume.
Both directions are handled automatically, with strict isolation maintained between internal and external users — each is restricted to its own directories, and neither can access the other's data.
Background and Rationale¶
Laboratory workflows often generate operational files — sample sheets, run sheets, instrument outputs — that need to move reliably between on-premises instrumentation, cloud storage, and external collaborators or downstream processing systems.
This solution consists of:
- A standard file share on the lab side, so no special client software or workflow changes are needed for lab users or instruments.
- A fully managed SFTP endpoint for external partners, removing the need to operate a dedicated external-facing server.
- Automated synchronization between the two, so files appear on each side without manual intervention.
Intended Audience¶
- Laboratory users and instrument systems that need to publish operational files for external consumption, or consume files submitted by external partners.
- External partners and collaborators who need a simple, secure way to exchange files without gaining broader network access.
- Hybird File Transfer Solution Team responsible for onboarding new labs or partners onto the shared file exchange model.
Current Status¶
This solution is currently implemented as a Minimum Viable Product (MVP). It demonstrates the feasibility of the architecture and validates the core design assumptions around access control and isolation. Broader production-readiness work (high availability, full monitoring rollout, formal support processes) is planned as a follow-on effort and is outside the current scope.
