Simultaneous Connections, Not Per-User Licenses: Right-Size Video Conferencing for EU Organizations

Across Europe, many organizations still pay for video conferencing as if every person or every meeting needs a separate license. Per‑user and per‑meeting models look simple on paper, but they embed structural waste: you pay for peak entitlements on every “host,” even though only a fraction of users are active at any given time, and you risk overage fees when large events exceed your plan’s limits.

A simultaneous‑connections model turns that logic on its head. With bbbserver.com, you subscribe to a fixed pool of concurrent connections—all the participants who can be connected at the same time—while running an unlimited number of sessions. Whether you operate five small meetings or one larger session, the same capacity is shared. If you subscribe to 100 simultaneous connections, you can run:

• Ten classrooms with 10 participants each.
• Two management workshops of 30 participants and four support huddles of 10.
• One 90‑person training plus a 10‑person project stand‑up.

You are paying for actual concurrent usage, not for dormant host licenses or a cap on how many meetings you can schedule. This approach aligns costs directly with demand, simplifies budgeting, and removes the need to predict which individuals require a “host” seat in a given month.

For EU organizations, the economic benefits come without compromising compliance. bbbserver.com runs entirely on European servers, within ISO 27001–certified data centers, and is fully GDPR‑compliant—so data processing, storage, and auditing remain within the European regulatory framework.

How to Right‑Size Capacity and Calculate Total Cost of Ownership

Right‑sizing is straightforward once you translate headcount into simultaneous connections. Use the following method to determine your capacity and total cost of ownership (TCO).

1) Profile your audiences and sessions

• Identify user groups (students, teachers, staff; teams; departments; citizens).
• Classify session types (classes, trainings, project meetings, town halls, exams, public hearings).
• Estimate average group sizes by type and how often each type occurs.

2) Estimate the concurrency factor

• Concurrency is the percentage of users connected at the same time. For a school, it might be 10–25% during typical hours; for an enterprise, daily peaks may sit around 8–15%; for a municipal body, concurrency may be low most days with occasional high‑peak events.
• If you have historical usage from any platform, use peak concurrent participants as your baseline.

3) Convert to simultaneous connections

• Multiply expected participants at peak by average session size to see how many parallel rooms you will run.
• Remember: every connected participant—moderators and attendees—consumes one connection.

Example:

• A higher‑education faculty expects up to 18 seminars of 25 participants running simultaneously, plus five support meetings of 6 participants.
• Required connections ≈ (18 × 25) + (5 × 6) = 450 + 30 = 480.
• Add a safety buffer of 10–20% for late joiners and unforeseen overlap: 528–576. Choose the next tier that accommodates this range.

4) Plan for peaks

• Seasonal spikes (exams, orientation, public consultations, town halls) may temporarily double demand.
• Options to handle peaks:
  • Maintain a permanent buffer above normal usage if peaks are frequent.
  • Schedule high‑impact events at off‑peak times to reuse capacity.
  • Use live streaming options for one‑to‑many delivery, reserving interactive connections for speakers and panelists.
  • Coordinate temporary capacity adjustments when major events are known in advance.

5) Calculate TCO

• In a per‑host model, TCO ≈ (number of host licenses × monthly fee) + webinar/large‑meeting add‑ons + storage/recording fees + support/billing overhead + potential overages.
• In a simultaneous‑connections model, TCO ≈ (capacity tier × monthly fee) + storage/recording needs aligned to actual usage + minimal administrative overhead, because you are not managing named hosts or per‑meeting quotas.

Budget predictability improves because costs scale with the single metric that matters: concurrent usage. As your organization grows, you increase capacity tiers only when real‑world concurrency grows—not when you add new employees or create more meeting rooms.

Three Practical Scenarios: Schools, Enterprises, Public Institutions

1) Schools and universities

• Challenge: Many institutions pay for teacher “host” licenses and student add‑ons, despite predictable timetables that create defined peaks. Costs balloon when exams and oral defenses run concurrently.
• Capacity approach: Map your timetable blocks. If a typical peak involves 35 classrooms of ~20 participants, you need approximately 700 connections. Add a 15% buffer for late joiners and administrative sessions (805 total).
• Exams and defenses: Concentrated events can produce short‑term spikes. Two practical strategies:
  • Stagger exam sessions within the day to reuse capacity across time slots.
  • For large plenary briefings, stream to viewers while limiting interactive connections to exam staff.
• Economic outcome: Instead of maintaining hundreds of individual licenses year‑round, you pay only for the bandwidth of real, concurrent teaching. You can also run unlimited extra sessions (ad‑hoc tutorings, parent meetings) as long as you stay within the same pool.

2) Enterprises and large organisations

• Challenge: Knowledge workers have fluctuating meeting loads; named “host” plans oversubscribe capacity and require webinar add‑ons for all‑hands meetings.
• Capacity approach: Suppose 1,200 employees with an observed peak concurrency of 12% across 6–8 meetings per team. That’s about 144 concurrent participants. Add 20% for cross‑functional workshops and external guests, rounding to ~175 connections.
• Town halls and launches: For monthly events with 600 viewers and 10 speakers, you can:
  • Allocate interactive connections to speakers and key moderators.
  • Offer a live stream for viewers to watch securely with Q&A handled via chat or moderated questions.
  • Record the session for on‑demand viewing, avoiding repeat presentations and spreading impact without extra live capacity.
• Economic outcome: The capacity pool remains lean for day‑to‑day work, yet the platform supports big moments without permanently upgrading every employee license or buying separate webinar products.

3) Public institutions and agencies

• Challenge: Public bodies must meet stringent privacy requirements and serve citizens reliably. Per‑meeting or per‑host plans can complicate budgeting for consultations, committee hearings, and cross‑agency work.
• Capacity approach: If you run daily operational meetings with a peak of 80 participants across multiple small rooms, plan for 100–120 connections including a buffer for emergent events.
• Peaks: For public hearings or press briefings, a live stream ensures broad reach while preserving interactive slots for officials and invited speakers. Scheduling tools help avoid clashes among departments.
• Compliance: With all servers located in Europe and data centers certified to ISO 27001, and with full GDPR compliance, you can document data residency and security controls for audits and DPIAs without routing data outside the EU.
• Economic outcome: Transparent, capacity‑based spend aligns with public accountability and procurement requirements, while service levels remain consistent during surges.

Streamlined Operations with the Tools You Already Need

bbbserver.com is built on the open‑source BigBlueButton, then enhanced for organisational use. Beyond cost and compliance alignment, you gain features that reduce administrative overhead and improve user experience across devices (PCs, Macs, tablets, and smartphones):

• Scheduling and room management

  • Create, manage, and distribute meeting links with fine‑grained controls for roles and permissions.
  • Coordinate departmental rooms and recurring sessions without juggling host entitlements.

• Session recordings and live streaming options

  • Capture trainings, classes, and briefings for on‑demand viewing, lowering repeat session costs.
  • Use streaming for high‑audience events to conserve interactive connections and reach larger groups.

• Collaborative classroom and workshop tools

  • Whiteboard for visual explanation and annotation.
  • Breakout rooms for group exercises and team discussions.
  • Screen sharing for demonstrations and support.

• Consistent experience at scale

  • Run unlimited sessions within your capacity pool—no arbitrary meeting caps.
  • Apply uniform policies for all rooms (lobby, muting, recording) to simplify governance.

These capabilities consolidate workflows that might otherwise require multiple add‑ons in per‑host ecosystems, further reducing TCO. Administrators no longer reconcile named licenses, track per‑meeting quotas, or negotiate separate webinar packages—capacity is the single lever.

Putting It All Together: A Cost‑Efficient, Compliant Path Forward

• Align cost with actual usage: Pay for simultaneous connections, not for idle host licenses or per‑meeting fees.
• Size with confidence: Estimate concurrency, add a modest buffer, and adjust over time as your patterns become clearer.
• Handle peaks gracefully: Schedule intelligently, use live streaming for one‑to‑many events, and adjust capacity when major events are anticipated.
• Standardise your toolset: Scheduling, recordings, live streaming options, whiteboard, breakout rooms, and screen sharing are available out of the box, across devices.
• Meet EU requirements by design: All servers are in Europe, data centers are ISO 27001–certified, and the service is fully GDPR‑compliant.

By moving from per‑host or per‑meeting licensing to a simultaneous‑connections model, EU schools, enterprises, and public institutions eliminate structural waste, simplify compliance, and gain a platform that fits how people actually meet and learn today.
