Amazon RDS for MariaDB Now Covered by RDS SLA
In October of 2015, we added support for the popular open source MariaDB database in Amazon RDS and have since seen rapid adoption by customers. Amazon RDS supports MariaDB instances running in Single-AZ or Multi-AZ configurations in all AWS regions. Today we are extending the RDS Service Level Agreement ("SLA") that covers Multi-AZ instances for MySQL, Oracle, and PostgreSQL to include Amazon RDS for MariaDB.
The RDS SLA affirms that AWS will use commercially reasonable efforts to make Multi-AZ instances of Amazon RDS available with a Monthly Uptime Percentage of at least 99.95% during any monthly billing cycle. In the event Amazon RDS does not meet the Monthly Uptime Percentage commitment, affected customers will be eligible to receive a service credit.
Multi-AZ deployments are perfect for production database workloads. When you provision a Multi-AZ DB instance, Amazon RDS synchronously replicates your data to a standby instance in a different Availability Zone (AZ). Each AZ runs on its own physically distinct, independent infrastructure, and is engineered to be highly reliable. In case of an infrastructure failure (for example, instance hardware failure, storage failure, or network disruption), Amazon RDS performs an automatic failover to the standby, so that customers' applications can resume database operations as soon as the failover is complete.
Please see the RDS SLA for details on our Monthly Uptime Percentage commitment and service credits. You can also learn more about Multi-AZ deployments, and launch a Multi-AZ RDS instance using the AWS Management Console for RDS.
