IONOS Cloud DBaaS for MariaDB
A fully managed MariaDB service on the German IONOS Cloud, with clusters of up to five instances, automatic failover, backup retention of up to a year, and Terraform support.
IONOS Cloud’s Database as a Service includes a managed MariaDB offering, which IONOS describes as MySQL-compatible. Clusters are created in the Data Center Designer, the API, or with the ionoscloud_mariadb_cluster_v2 Terraform resource, and can run up to five instances: a primary and secondaries that are promoted automatically on failover. Replication between them is asynchronous, so a failover can lose the most recent committed transactions.
Each cluster runs inside the customer’s private network on a chosen IP, with a configurable maintenance window and backup retention from 1 to 365 days. The current v2 service recommends MariaDB 10.11 or later; v1 clusters were migrated automatically before their August 2026 decommissioning. IONOS is a German provider and runs the service in its European data centers.
