Amazon Aurora Multi-Master allows you to create multiple read/write master instances across multiple Availability Zones. This enables applications to read and write data to multiple database instances in a cluster, just as you can read across Read Replicas today.

Multi-Master clusters improve Aurora's already high availability. If one of your master instances fail, the other instances in the cluster will take over immediately, maintaining read and write availability through instance failures or even complete AZ failures, with zero application downtime.

Today’s single-master Aurora supports one write instance and up to 15 promotable read-only replicas in a single database cluster. The primary writer instance can execute up to 200,000 write operations/sec on an r4.16xlarge. Workloads that require even higher write throughput will benefit from horizontally scaling out their writes with additional master instances.

The preview will be available for the Aurora MySQL-compatible edition, and you can participate by filling out the signup form.

Amazon Aurora is a fully managed relational database that combines the performance and availability of high-end commercial databases with the simplicity and cost-effectiveness of open source databases.
