Ensure that your Amazon Neptune graph database clusters are using Multi-AZ deployment configurations to enhance High Availability (HA) through automatic failover to read replicas in the event of a failure such as an Availability Zone (AZ) outage, an internal hardware or network outage, a software failure or in case of planned system maintenance.
With Multi-AZ feature enabled, AWS Neptune service creates and maintains synchronous replicas across different Availability Zones to provide data redundancy, eliminate I/O freeze-ups and minimize latency during system backups. Running a Neptune database cluster with Multi-AZ enabled will improve availability during system maintenance and help protect the databases against failure and Availability Zone disruption.
To determine if your Amazon Neptune database clusters are using a Multi-AZ configuration, perform the following actions:
To enable Multi-AZ for an existing Amazon Neptune database cluster, you must recreate that cluster with the necessary configuration. In order to relaunch the required cluster, perform the following actions:
