Cloudera Operational Database supports Multiple Availability Zones (Multi-AZ) on Google Cloud Platform (GCP)

Cloudera Operational Database ensures high availability and fault tolerance through the utilization of Multi-AZ deployments. A Multi-AZ deployment signifies that the compute infrastructure for HBase's master and region servers is distributed across multiple Availability Zones (AZs). This configuration guarantees that in the event of an outage in a single availability zone, only a fraction of the Region Servers are impacted, allowing clients to automatically failover to the remaining servers situated in the available AZs.

Support for Multi-AZ deployments of Cloudera Operational Database is now available on Google Cloud Platform (GCP) environments too. However, Cloudera Operational Databases provisioned with the Micro Duty scale type do not accommodate Multi-AZ configurations.

Cloudera Operational Database does not support Multiple Availability Zones (Multi-AZ) while using the Micro duty scale type

Cloudera Operational Databases provisioned with the Micro Duty scale type are no longer compatible with Multi-AZ configurations. Since these deployments are intended solely for testing and development environments, Multi-AZ support is not necessary. Therefore, the option to configure Multi-AZ networking for Micro scale operational database clusters has been removed, and Micro clusters are strictly limited to Single-AZ deployments, accurately reflecting their architectural capabilities.
