What Danube Cloud is
Danube Cloud is open-source software for building, managing, and automating cloud data centers on your own hardware. It supports both hardware and container virtualization, with provisioning automation and a centralized, mobile-friendly web portal for managing data centers and viewing physical and virtual resource use. Its networking includes VLAN and VXLAN, and its API supports cloud management and integration with external systems such as ERPs and e-shops. Virtual machines use compute-node local storage with ZFS; recovery options include snapshots, incremental backups, replication to a backup compute node, and VM image repositories. The software supports multi-tenant virtual data centers with resource management, role-based access control, and Zabbix monitoring with automated configuration. It runs on compute-node hardware and is based on SmartOS, called ErigonOS in its modified form in the documentation. Danube Cloud is free, and its Community Edition repository identifies Apache License 2.0. It is available for self-hosted deployment, Linux, web, and API use.
