Collaboration should be easy and natural for those involved. In the background, however, it quickly becomes complex: authorisations must be maintained, sensitive content protected, data kept findable and external access controlled. At the same time, central IT should remain capable of acting without having to manually manage every release or query.

OpenCloud combines scalable file management with productive collaboration, clear workspaces and an operating model that remains manageable even with very large data sets.

Collaboration needs more than storage space

Once several groups are working on the same data, traditional file storage is no longer sufficient. Workspaces are needed that match the organisation's structures: for teams, projects, institutes, courses or collaborations with external partners. Spaces take on this task in OpenCloud. They bundle files, folders, tags and authorisations in a shared context. This means that content does not belong to individual user accounts, but remains anchored in the team or project context. This is particularly important when people leave the organisation, project groups are reassembled or collaborations exist over a longer period of time. The data remains where it belongs: in the workspace of the project, group or organisational unit.

This results in a practical relief effect for IT. Space admins can manage access for users and groups independently. Many day-to-day changes can be implemented directly in the department, while central IT retains the overarching framework for security, operation and governance.

Files must work in everyday life

In everyday working life, it is not the architecture alone that determines whether a platform is accepted. The decisive factor is whether files are quickly accessible, changes are visible and collaboration works without detours.

OpenCloud can be used in the browser, via desktop client, mobile app or file manager. Files can be opened, synchronised, shared and edited together. The interface remains responsive even with many files. Changes appear immediately in the web interface without the need to reload.

When several people are working in parallel, versioning and restoration become particularly important. Previous file statuses can be restored, editing conflicts are reduced and data loss is better prevented. Offline access, resumable uploads and files on demand also support work on different devices and in changing work environments.

With increasing data volumes, the question of how content can be retrieved and reused is also becoming more important. Full-text and metadata searches, flexible tags and filter options help to structure data across teams, projects and research areas. This creates not just a file repository, but a usable data space.

The technical foundation must grow with it

Behind the ease of use is an infrastructure that must reliably map growing data volumes, many parallel accesses and different end devices. Requirements can vary greatly, especially in universities and research: Some projects work primarily with documents, others with image data, measurement series, simulations or extensive data collections.

The microservices architecture of OpenCloud supports many parallel accesses, high loads and different end devices. Petabytes of data can be operated in the background via various storage backends, such as S3, CephFS, GPFS or POSIX.

An important difference lies in the storage concept. OpenCloud does not require a classic database for file storage. Files and meta information are stored directly in the file system. This reduces technical complexity and facilitates maintenance, backup, recovery and troubleshooting. At the same time, the platform can be integrated into existing IT landscapes. User directories such as LDAP and Active Directory, virus protection, digital rights management and other security components can be integrated.

Sharing must not mean loss of control

The more people, organisations and locations work together, the more important controlled sharing becomes. External partners should be able to be integrated without passing on sensitive content unprotected. Access must remain traceable, approvals must be limited and authorisations must be clearly controllable.

OpenCloud supports encryption during transmission, two-factor authentication, role-based authorisations, virus protection and guidelines for strong passwords. Files and folders can be shared in a controlled manner, for example via password-protected links or with clearly defined rights for reading, editing and uploading. Secure View can watermark documents and makes unauthorised sharing of sensitive content more difficult. Audit logs record file uploads, approvals and logins, among other things, and thus support traceability and audits.

Collaboration across multiple locations can also be mapped. Federation connects multiple OpenCloud installations and other compatible systems via the Open Cloud Mesh (OCM) protocol. This allows files to be made available across organisational boundaries in a controlled manner without restricting collaboration to a single central instance.

Open, accessible and controllable in the long term

Openness plays a key role because digital collaboration in universities and research needs to work in the long term. OpenCloud is 100% open source. This gives institutions more transparency and freedom in terms of operation, integration and further development. The platform is also designed for different user groups: IT administrators, researchers, teaching staff, administration, students and external partners work via an intuitive web interface, reliable synchronisation, integrated web office and continuous versioning.

The web interface also meets accessibility standards such as WCAG 2.1 AA, BITV 2.0 and EAA. OpenCloud has also been awarded the Blue Angel DE-UZ 215 ecolabel for resource- and energy-efficient software.

File storage becomes a basis for work

In the end, it's not just about storing files. The decisive factor is whether data rooms grow with projects, whether teams can work independently, whether sensitive content remains controllable and whether IT can operate and integrate a platform in the long term.

OpenCloud combines these levels in one platform: collaboration remains clearly organised in Spaces, data can be searched, versioned and synchronised, existing systems can be integrated and operations remain manageable thanks to the database-free storage concept. Security and audit functions also ensure that collaboration remains traceable.

This makes file collaboration more than just file storage: a resilient working basis for growing data volumes, changing project structures and productive collaboration in research, teaching and administration.
