Scalable front-end architecture for sovereign video conferencing

Technical excellence as the basis for digital independence

The demands placed on digital communication are growing rapidly—especially in businesses and public administration. Complex IT landscapes, security requirements, and the need to be able to work reliably even under difficult conditions call for solutions that can do more than standard tools.

With its sophisticated front-end architecture, OpenTalk demonstrates how modern video conferencing can be implemented in a technically superior and future-proof manner.

Architecture that combines scalability and stability

A key strength of OpenTalk is the clear separation between the dashboard and the conference room. While the dashboard works particularly efficiently via the REST API, intelligent caching, and optimized data queries with the Redux toolkit, real-time communication in the conference room has its own unique requirements. Here, OpenTalk relies on LiveKit to ensure stable connections and consistently reliable use, even in the event of device failures or unstable networks.

This architecture reduces system complexity, improves maintainability, and enables enterprise-level video conferencing to be scaled.

Superior media management as the key

Real-time communication presents a particular challenge for developers and users alike: media sources must be processed consistently and securely. OpenTalk solves this with a sophisticated abstraction layer that synchronizes the browser's video and audio streams with LiveKit. This central management orchestrates device permissions such as camera, microphone, screen sharing, and network connections between both API levels – ensuring a stable user experience in every situation.

Whether switching from the lobby to the conference, connecting the camera and microphone, or using advanced features such as background blur, OpenTalk ensures transparency, security, and optimal performance.

OpenTalk offers comprehensive interoperability for heterogeneous IT landscapes

OpenTalk also supports various dial-in options. Public institutions in particular often have very different technical requirements: modern end devices, older conference hardware, variable bandwidths. OpenTalk is designed to be both powerful and adaptable. Adaptive streaming technologies, intelligent bandwidth control, and support for classic dial-in methods such as SIP ensure that all users can participate—without additional infrastructure investments.

This means that even smaller administrations and companies can benefit from a centralized, sovereign solution.

Future-proof thanks to modern technologies

OpenTalk deliberately relies on open standards and open source. The OpenTalk front end relies on proven technologies: React as a modern JavaScript framework, Redux for central state management, and TypeScript for type-safe communication with various backend interfaces. This combination ensures stability and high developer productivity. The use of WebRTC as a global communication standard also guarantees interoperability and protects against vendor lock-in.

This technological basis makes OpenTalk expandable and maintainable in the long term – and secures investments in the communication infrastructure of today and tomorrow.

Security and compliance right from the start

Security is not an afterthought, but an integral part of the architecture. OpenTalk relies on security by design: encryption, no storage of sensitive data in the browser, clear separation of clients, and deep integration into existing identity and authorization systems.

Companies and public authorities benefit from verifiable GDPR compliance, auditability, and transparent control over data flows – essential building blocks of digital sovereignty.

Architecture as a success factor for digital sovereignty

The architecture of OpenTalk shows that technical excellence and practical usability are not a contradiction. It enables stable, scalable video conferencing, protects sensitive data, and at the same time creates the basis for long-term independence.

OpenTalk supports companies and administrations in implementing digital sovereignty not only as a goal, but as a lived reality in daily communication.
