Virtual Cluster

Premium plan feature

Virtual Cluster requires the Premium plan. To upgrade, see Plans.

A virtual cluster pairs two physical clusters as active and standby across availability zones. On a failure in the active AZ, VeloDB Cloud automatically fails over to the standby cluster. Real-time data synchronization ensures continuity and prevents data loss.

virtual cluster detail

From the detail page you can:

  • Switch active/standby — Promote the standby cluster to active. Use this for planned maintenance or to restore the original assignment after a failover.
  • Delete — Remove the virtual cluster. This does not delete the underlying physical clusters.
