Virtual Servers in the Admin Data Center¶
- mgmt01 - central web management server.
- mon01 - main monitoring server running Zabbix.
- cfgdb01 - configuration database server running Apache ZooKeeper.
- dns01 - primary DNS server running PowerDNS.
- img01 - central image server used for storing virtual server disk images.
- opnsense01 - (optional) central router between admin and external network.
The root accounts in each virtual server have the first compute node’s public SSH key set during installation and therefore are accessible from first compute node via SSH.
The Danube Cloud internal virtual servers cannot be reinstalled or redeployed to an existing Danube Cloud infrastructure. Please make sure that you perform regular backups of all Danube Cloud internal servers.
