The most awaited feature of RDS for DB replication.
“We are excited to announce the release of Read Replicas, a new feature that makes it even easier to scale MySQL database deployments to meet the performance demands of high-traffic web applications. You can now create one or more replicas of a given source DB Instance and serve incoming read traffic from multiple copies of your data. This new database deployment option enables you to elastically scale out beyond the capacity of a single DB Instance for read-heavy database workloads. In conjunction with the release of Read Replicas, we are also announcing lower prices for High Memory DB Instance classes.” –Amazon
I’m getting ready to scale DB read access using RDS. 😉
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.
