Cloud Architecture at Stackscale

The infrastructure is designed to combine the flexibility of OpenNebula with the robustness of bare-metal hardware:
  • Frontend + VPN deployed on Stackscale’s internal cluster.
  • Private networks to interconnect hosts and VMs.
  • Public network with dedicated IPs for external services.
  • Multi-datacenter deployment across Madrid (MAD3 and MAD4) and Amsterdam (AMS2) to ensure true geographic high availability.
