description: |
|
||
|
|
Ensure that your Amazon ElastiCache Redis cache clusters are using a Multi-AZ deployment configuration to enhance reliability through automatic failover.
|
||
|
|
impact: |
|
||
|
|
Disabling ElastiCache Redis Multi-AZ can lead to data loss and increased downtime in the event of a primary node failure, as failover to a secondary node in a different availability zone will not occur automatically.
|
||
|
|
remediation: |
|
||
|
|
Enable Multi-AZ replication in the ElastiCache Redis settings or create a new cluster with Multi-AZ enabled to ensure high availability.
