Amazon just announced the new feature for Amazon RDS.
Amazon RDS – Multi-AZ Deployments For Enhanced Availability & Reliability
Amazon RDS simplifies many of the common tasks associated with the deployment, operation, and scaling of a relational database. You don’t have to worry about acquiring and installing hardware, loading an operating system, installing and configuring MySQL, or managing backups. In addition, scaling the processing power or storage space available to your database is as simple as an API call.
When we rolled out Amazon RDS last October, we also announced plans to have a “High Availability” option in the future. That option is now ready for you to use, and it’s called “Multi-AZ Deployments.” AZ is short for “Availability Zone”; each of the four AWS Regions is comprised or two or more such zones, each with independent power, cooling, and network connectivity.
The availability and reliability characteristics of Multi-AZ deployments make them well suited for critical production environments.
