Case 1 — Single-site sovereign
One data centre. Static IP. Full stack on-premises. Best for ministries and defence forces with their own infrastructure. Synapse, PostgreSQL, Redis, MinIO, LiveKit, and Coturn run inside your network boundary.
Deploy Saydhi the way your infrastructure demands.
Two supported architectures, clear sizing guidance, and honest responsibility boundaries.
Case 2 — Hybrid edge
On-premises core plus a VPS edge for UDP media relays. For organisations without static IPs or with UDP-restrictive networking. Signalling and storage stay on-prem; only media relay happens at the edge.
Infrastructure sizing
| Size | Users | Notes |
|---|---|---|
| S | Up to 500 | Single VM: 8 vCPU, 32 GB RAM, 500 GB SSD. One DB node. |
| M | 500 to 5,000 | 3-node cluster. Separate DB with replica. Media relay on dedicated nodes. |
| L | 5,000 to 50,000 | Multi-zone deployment. Synapse workers split. Dedicated media edge nodes. |
| XL | 50,000+ | Custom engagement. We work with your architects. |
Shared-responsibility matrix
Saydhi
- Software releases and security patches
- Coordinated vulnerability disclosure
- Architecture and sizing guidance
- Professional services (optional)
- Documentation and runbooks
Customer
- Compute, storage, and network infrastructure
- TLS certificates (or use Cloudflare Origin)
- User identities and SSO integration
- Operational staffing and on-call
- Incident response within your environment
Installation and onboarding
From signed contract to production: typically 2 to 6 weeks, depending on deployment model and customer readiness. We provide guided installation, runbook handover, and a scheduled knowledge-transfer session.
High availability and scaling
Active-active Synapse workers behind a load balancer. PostgreSQL with streaming replication. Redis Sentinel for coordination failover. LiveKit scales horizontally per-room. Media edge nodes add capacity independently.
Air-gapped deployments
For defence and sovereign environments without internet egress. Offline artifact bundles, signed update channels, and local mirror guidance. Contact us for the air-gapped deployment guide.
