Amazon RDS adds new events reporting the cause of an Amazon RDS Multi-AZ automated database failover so that you can detect and respond faster. You can view these failover reasons in the event log.

Amazon RDS Multi-AZ deployments provide enhanced availability and durability for RDS database (DB) instances, making them a natural fit for production database workloads. Amazon RDS detects and automatically recovers from the common failure scenarios for Multi-AZ deployments so that you can resume database operations as quickly as possible without administrative intervention. Amazon RDS automatically performs a failover in the event of any of the following:

  • Loss of availability in primary Availability Zone
  • Loss of network connectivity to primary DB instance
  • Compute unit failure on primary DB instance
  • Storage failure on primary DB instance

Additionally, this update also reports new events on planned failover due actions such as scaling compute resources or applying updates during a maintenance window.

Amazon RDS makes it easy to set up, operate, and scale a relational database in the cloud. Learn more about event notifications from your database instances from the Amazon RDS User Guide. See Amazon RDS Pricing for pricing details and regional availability. Create or update a fully managed Amazon RDS database in the Amazon RDS Management Console.

Support for Publishing New Events on High Availability of Multi-AZ Deployments is available in the Amazon Web Services China (Beijing) Region, operated by Sinnet, and the Amazon Web Services China (Ningxia) Region, operated by NWCD.
