OpenTalk Hosting in Germany
WZ-IT designs sovereign video conferencing with controller, media paths, identity, optional recording and a reliable operating model.
About the technology
Operate video conferencing as a distributed real-time platform
OpenTalk consists of several required and optional services. Signalling, WebRTC media, identity, mail and optional recording or SIP must work together.
We assess users, concurrent meetings, participants, locations, browsers, networks and optional capabilities and design an appropriate self-hosted architecture.
OpenTalk for meetings and video conferencing
Browser-based video meetings
Provide meetings through modern browsers without mandatory client installation.Controlled media paths
Design WebRTC, STUN and TURN for locations, firewalls and the required accessibility.Identity and invitations
Integrate user login, guest access, rooms and invitations with identity and mail systems.Moderation and meeting tools
Configure roles, moderation, polls and further capabilities for the intended use.Optional recording and SIP
Add recording, streaming or dial-in as separate services with storage and privacy controls.Platform monitoring
Monitor controller, media components, queues and network paths.Migration and takeover
Assess existing data and configuration, migrate them in a test run and move to managed operations through a controlled cutover.Identity and secure access
Secure SSO, roles, administrative paths and external access for the application and existing infrastructure.Backup and recovery
Back up all stateful components consistently and document the recovery path for the agreed scope.Updates, monitoring and operations
Monitor and update the application and its technical dependencies and operate them under the agreed service level.
Operations beyond installation
Operate OpenTalk as a real-time communications platform
Video conferencing requires more than a web application. Signalling, media paths, STUN/TURN, identity, recording and network quality interact.
Conference platform
Operate the web interface, controller and platform services with controlled versions.Media and network
Test WebRTC, STUN/TURN, bandwidth and firewall paths in practice.Identity and calendars
Connect authentication, rooms and existing communication services.Monitoring and support
Observe quality, capacity, errors and optional recording services.
Area
Responsibility for platform and conference quality
WZ-IT operates the agreed platform; endpoints, local networks and business meeting rules are shared or customer responsibilities.
| Area | Responsibility | Scope and boundaries |
|---|---|---|
| OpenTalk services | WZ-IT | Deployment, configuration, updates, monitoring and technical maintenance. |
| STUN/TURN and media paths | WZ-IT | Server-side network services, certificates and reachable media paths. |
| Identity and users | Shared | We integrate authentication; the customer defines groups and authorised users. |
| Endpoints and site networks | Shared | We analyse requirements; the customer provides suitable clients, headsets and local bandwidth. |
| Recording and meeting rules | Customer | Consent, content, moderation and permitted recording remain with the customer. |
| SIP, recording and custom integration | Optional WZ-IT service | Additional services are integrated after feature and licensing review. |
Hosting & operations
How much does OpenTalk hosting cost?
We combine the right compute size with ongoing operations, backups, monitoring and a service level appropriate for the criticality of OpenTalk. High availability and recovery targets are designed separately where needed.

As an alternative to managed hosting in the data centre, WZ-IT provides the hardware, configures OpenTalk, and handles hardening, monitoring, updates, backup and technical support. Access can be limited to the internal network or enabled through VPN and existing identities.
View WZ-IT App Node →Sizing and deployment
Size OpenTalk by parallel conferences and media load
Participants per room, concurrent rooms, video quality, TURN share and recording determine network and compute requirements.
| Usage scenario | Technical starting point | Key factors |
|---|---|---|
| Small internal meetings | Conference assessment | Typical rooms, clients and network paths are tested. |
| Many parallel teams | Capacity planning | Concurrent rooms, media paths and TURN utilisation are modelled. |
| Large events | Load test and target architecture | Participant profile, presentation and moderation are tested in practice. |
| Recording, SIP or HA | Individual platform | Additional services, storage, recovery and availability are designed separately. |
- OpenTalk is priced individually based on participants, concurrency, media paths and additional services.
Sizing and deployment
OpenTalk deployment models
Platform and media paths can run centrally, in your cloud or on-premises; public reachability is usually still required.
WZ-IT platform
Dedicated environment with controlled public access and operations.Your cloud
Deploy in your account with suitable network connectivity.On-premises
Operate in your data centre with planned external media paths.Hybrid
Keep identity or internal services local while exposing conference and media paths in a controlled way.
Target architecture
Design signalling, media and identity together
Browsers and clients connect through secured platform services; media paths require direct or TURN-relayed connections depending on the network.
Participants and endpoints
Browsers, camera, microphone and site network.
TLS, WebRTC and TURN
Reachable signalling and media paths through firewalls and NAT.
Login and rooms
Identity providers, guest access and moderation roles.
OpenTalk
Controller, conferences, moderation and platform services.
Media infrastructure
WebRTC components, STUN/TURN and network quality.
Optional recording
Recording services, storage and retention after approval.
Quality monitoring
Metrics, errors, utilisation and technical events.
Achievable media quality also depends on endpoints, participant networks and Internet paths outside the platform.

Size S with 2 vCPU, 4 GB RAM, 80 GB NVMe SSD costs €129.90. We check which size OpenTalk needs in production before provisioning. Size M (4 vCPU, 8 GB RAM, 80 GB NVMe SSD) costs an extra €29.90 excl. VAT, L (8 vCPU, 16 GB RAM, 80 GB NVMe SSD) an extra €89.90 excl. VAT and XL (16 vCPU, 32 GB RAM, 80 GB NVMe SSD) an extra €199.90 excl. VAT, each per month. Additional storage costs €4.99 excl. VAT per 50 GB and month.
- No. WZ-IT does not limit the number of users. How many users can work smoothly at the same time depends on usage and the chosen instance size XS to XL.
- OpenTalk hosting can be cancelled monthly, with no minimum term and 30 days' notice to the end of the month.
- In German data centres operated by a German provider, without US clouds. The data centres are ISO 27001 certified and BSI C5 attested.
- We provide a production instance within a few business days. For a trial, we set up a test instance, usually on the next business day; it runs free of charge for 7 days and without payment details.
- Yes. One .de domain is included with every hosting plan. Alternatively, connect your own domain or subdomain with a CNAME record.
- Yes, server components can run on-premises. Signal and media paths still need secure reachability for external participants.
- Concurrent rooms, participants, video quality, TURN usage and additional services change network and resource requirements substantially.
- Yes. We design supported OIDC or SSO paths, guest access, roles and emergency administration.
- Optional recording and SIP components can be integrated after review of version, licence, storage and privacy requirements.
- We monitor server services, resources and network metrics. Endpoints and participant networks form part of testing but remain partly outside our control.

Reviews & projects
Client feedback and projects worldwide
WZ-IT moved our studio infrastructure from decentralised individual devices to a central platform: every site is securely connected via VPN, new devices are onboarded automatically and an entire site is provisioned from a template, without manual steps on location. What impressed me most is the breadth and depth of their knowledge: Timo and Robin are not a typical IT provider who sets up a server and leaves. The two of them think their way into highly complex infrastructure and software topics, work through every requirement we put in front of them, and build networking, provisioning and operations so that everything fits together in the end. WZ-IT is an excellent partner for complex software, network and architecture projects.
