Common questions

How can I create users/roles/databases/...?

Use the default admin user to create users/roles/databases/... as you wish.

Can I access metrics/logs of my databases?

Metrics and logs of databases are automatically forwarded to your provisioned metrics Observability tenant.

You can find more information about provisioned metrics on the Observability documentation.

Are multi-region database clusters supported?

DBaaS maintains single-region database clusters. The platform creates database instances within a single region for simplicity and ease of management.

Why do all requests come from 192.168.x.y?

To ensure optimal distribution of incoming traffic and to enhance the fault tolerance of the database infrastructure, DBaaS uses a load balancer. The load balancer acts as an intermediary between the applications and the databases. Network Address Translation (NAT) translates the private IP addresses used within the database environment into a single public IP address that is visible to external applications.

Can I connect to my databases using a private network?

Yes, you can choose between private and public (or both) networking for your database. If you choose private networking, we share an OpenStack network with you which allows access to the database. Connect the network to a router to establish connectivity to the database.

Deleting the database also deletes the network and all ports in it. For this reason, we recommend against connecting other VMs to this network directly and prefer connecting them through a router.

What happens during maintenance windows?

To ensure optimal performance, security, and reliability of databases, scheduled maintenance windows are periodically designated for routine maintenance activities. This maintenance window reduces disruption to services and maximizes the efficiency of maintenance tasks. During a maintenance window, the following activities, among others, may take place:

  • Software Updates: the platform applies essential updates, patches, and security fixes to the underlying infrastructure and database software.
  • Performance Optimization: the platform fine-tunes database performance during maintenance windows to address identified bottlenecks or inefficiencies.

The database instance typically experiences brief downtime.

Are all resources (CPU/RAM) of the flavor available to the database?

We reserve 1.5 CPU and 1.5 GB memory on each node for system management software.

Can third-party tools be used with DBaaS?

Yes, in general. We do not support third-party tools. Selection, operation, and maintenance of such tools are the customer's responsibility.
