WebRTC: real-time business video infrastructure
Short answer
WebRTC (Web Real-Time Communication) is a set of open standards (W3C / IETF) built into browsers to transport audio, video, and data in real time, with DTLS-SRTP encryption. For enterprises, a WebRTC platform is the technical foundation of a controlled video stack: signaling, SFU, STUN/TURN, and a video API form the complete architecture.
Looking to integrate or embed a video room API programmatically? That intent is covered end to end on the video API hub. This page focuses on the underlying WebRTC platform and infrastructure.
What is WebRTC technically?
WebRTC covers four building blocks:
- Capture: camera, microphone, and screen sharing via browser APIs;
- Adaptive encoding: bitrate adjustment based on network conditions (simulcast, SVC);
- Encrypted transport: DTLS for negotiation, SRTP for media streams;
- ICE negotiation: establishing the optimal network path between participants.
Unlike HLS or RTMP, WebRTC targets sub-second latency — essential for real-time communication.
Why WebRTC for enterprise infrastructure?
| Criterion | WebRTC | Delayed protocols (HLS, RTMP) |
|---|---|---|
| Latency | Sub-second | 5–30 seconds |
| Browser integration | Native | Player or app required |
| Interactivity | Bidirectional | One-way |
| Encryption | DTLS-SRTP by default | Variable |
| Sovereign deployment | Open-source stacks | Often proprietary CDN |
For IT and engineering teams, WebRTC offers an auditable stack deployable with France hosting or on-premise, without dependency on a single closed binary.
How does a professional WebRTC architecture fit together?
- Signaling (HTTPS WebSocket): exchange of SDP metadata;
- ICE / STUN / TURN: NAT traversal and enterprise firewalls;
- SFU: selective forwarding for multi-participant sessions;
- Application layer: API, authentication, recording, moderation.
WebRTC vs WebSocket: what's the difference?
WebSocket transports text/binary messages between client and server. WebRTC transports peer-to-peer or SFU-routed media streams, with ICE negotiation and built-in video codecs. In practice, WebSocket often serves as the signaling channel; WebRTC carries the video itself.
Integration into existing systems
WebRTC integrates via:
- Video API: room creation, tokens, webhooks;
- Embedded video: iframe or SDK in an existing portal;
- Video integration: CRM, SSO, LDAP directory connections.

Open source stack and sovereignty
Open-source components (mediasoup, Jitsi, Janus, Pion…) enable building a sovereign business video platform hosted in France, with a controlled subcontractor chain — aligned with GDPR requirements. See the open-source WebRTC comparison and latency optimization guide when sizing the platform.
Key considerations for IT teams
- Firewall: plan documented TURN servers (UDP and TCP);
- SFU sizing: a 1:1 session ≠ a 50-participant meeting;
- Codecs: VP8, VP9, H.264, AV1 depending on browsers and IT policy;
- Monitoring: ICE metrics, bitrate, packet loss for ops runbooks.
WebRTC infrastructure selection criteria
Before comparing vendors or stacks, IT can structure evaluation around eight criteria:
| Criterion | Question to ask | Impact |
|---|---|---|
| Target latency | Synchronous interaction or broadcast? | SFU vs CDN choice |
| Connectivity | Documented TURN for corporate network? | Real connection rate |
| Sovereignty | SFU, TURN, logs in France/EU? | GDPR compliance |
| Integration | API, SSO, webhooks available? | SI time-to-market |
| Scalability | Horizontal SFU scaling? | Cost and SLA |
| Observability | ICE metrics, packet loss, dashboards? | Ops runbook |
| Open source | Auditable stack, no binary lock-in? | Long-term viability |
| Support | Firewall guide, incident runbook, DPA? | Operations |
Complete WebRTC infrastructure covers signaling, ICE/STUN/TURN, SFU and application layer: a missing component (often TURN) explains many production failures.
Scenario: remote customer support
An equipment maintenance company deploys WebRTC for remote pre-diagnosis:
- The customer opens a browser link (no installation);
- Signaling creates the session and authenticates the participant;
- TURN takes over if the client network blocks P2P;
- The SFU routes the stream to the support agent;
- An API webhook closes the CRM ticket at session end.

How does Leagora use WebRTC?
Leagora designs real-time video infrastructure on a WebRTC foundation: scalable SFU, documented TURN, video API, France or on-premise deployment. leagora.io documents the stack; business products live on the dedicated domains above.

FAQ
Is WebRTC a standard or a product?
It is an open standard (W3C / IETF), not a vendor. Each implementation (Google, Mozilla, open-source stacks) integrates it into its infrastructure.
Does WebRTC work behind a corporate firewall?
Yes, with properly configured and documented TURN servers. Without TURN, strict peer-to-peer connections frequently fail on corporate networks.
What latency should you expect with WebRTC?
Under normal conditions: 200 ms to 1 second for interaction.
Does WebRTC replace Zoom or Teams?
It replaces the transport layer in infrastructure you control (hosting, branding, SI integration).
Can WebRTC be deployed on-premise?
Yes: signaling, SFU, TURN, and storage on your datacenter. See France hosting for Leagora options.
Is WebRTC GDPR-compatible?
The standard alone does not guarantee compliance; governance (hosting, DPA, recordings) determines it.
Key takeaways
- WebRTC = open standards for real-time browser video.
- Pro architecture = signaling + ICE/STUN/TURN + SFU + API layer.
- Sovereignty = open-source stacks + France hosting.
