FEATURED PROJECT
Complete, modular SMB infrastructure
Just as secure, significantly faster and costs a fraction of AWS or Microsoft/Google Cloud.
~$250 / month. Cluster ready, modular stack on Hetzner dedicated hardware. Enterprise grade resilience (two power grids, UPS, generators). 10 VDI users (up to 50 site-to-site). Long-term backups are stored in a Hetzner Storage Box, replicated to an off-site Storage Box in Finland.
The stack can operate as a single node or scale to a cluster. Operating a cluster requires a dedicated firewall and shared NAS storage. All components are enterprise grade, ECC RAM and ZFS with ARC cache. In most cases, the 10 Gbit/s network sets the throughput limit. ~$1200 / month
✓ Dedicated 10Gbit/s WAN – 4ms to google and cloudflare
✓ Secured with CrowdSec, Suricata, IP/DNS Blocklists, WAF and Zero Trust Policy
✓ i9 13900 for fast Apps and snappy user interaction
✓ ECC RAM, mirrored datacenter SSDs, network redundancy
✓ Clustered nodes, two power grids, UPS and generators for high availability
✓ Backups restored in seconds. Offsite long-term storage (3-2-1 rule)
✓ Agent-based monitoring and centralized logs to spot issues early
✓ Optimized servers and lean installs prevent CPU spikes and keep I/O latency minimal
✓ Hands-off down to the BIOS level. Disk replacement on live systems, for free
✓ Modular, scalable design for fast deployment and future expansion
✓ One login or pre-installed VPN to connect to all company services
✓ Access VDI in a browser. Secure, fast and on any device
✓ Open source for low licensing costs
