CDP Operational Database (COD) supports Multiple Availability Zones (Multi-AZ) on AWS

Rising Star
COD ensures high availability and fault tolerance using Multi-AZ deployments. A Multi-AZ deployment means that compute infrastructure for HBase’s master and region servers are distributed across multiple AZs ensuring that when a single availability zone has an outage, only a portion of Region Servers is impacted and clients automatically switch over to the remaining servers in the available AZs.
Multi-AZ for COD is currently supported only on Amazon Web Services (AWS) environments. For more information, see Multi-AZ deployment on COD.

This is available starting in COD v1.22 and you do not need to upgrade to a higher version of COD to benefit from this feature.
