AWS Config Rule: RDS Multi AZ Enabled


Fernando Honig

Last Update 8 maanden geleden

Description: Checks whether high availability is enabled for your RDS DB instances. In a Multi-AZ deployment, Amazon RDS automatically provisions and maintains a synchronous standby replica in a different Availability Zone. 
For more information, see High Availability (Multi-AZ) in the Amazon RDS User Guide.

Note: This rule does not evaluate Amazon Aurora DB and Amazon DocumentDB instances.

Trigger type: Configuration changes

AWS Region: All supported AWS regions except Asia Pacific (Hyderabad), Asia Pacific (Melbourne), Europe (Spain), Europe (Zurich) Region

How to Resolve Manually

To resolve this manually, you will need to ensure that your RDS Instances (excluding Amazon Aurora DB & Document DB) have Multi-AZ Deployment enabled. This can be found above the Connectivity options in the RDS configuration step and below Storage.

With "Create standby instance" enabled, AWS will create a standby RDS instance in a different Availability Zone (AZ) to provide data redundancy and protect against any outages or issues with the main AZ which may be out of your control.

How to Resolve with StackZone

The StackZone remediation for this Config Rule will execute an SSM Document capable of enabling MultiAZ on an Amazon RDS Instance. This is a ModifyDBInstance API call to enable MultiAZ on the RDS Instance, targeting the RDS Instance which is showing as NON_COMPLIANT in the first part of the config rule initially.

To enable the Remediation for this Config Rule, head on over to Baseline Services -> Config Rules Regional -> Amazon RDS and enable RDS Multi AZ Enabled Remediation.
