Introducing the Radius for RDS Service!
We created Radius to help you save up to 80% on your monthly RDS bill. When running a production RDS database it is necessary to do so in a highly available manner. What this means is running multiple (and expensive) slave and read replica nodes in case the master RDS instance were to fail. These redundant instances spend 99.9% of their lives waiting for a failure to occur (and also facilitate seamless DB updates). This led us to take the decision to create our own HA solution for RDS which we call Radius. Radius integrates directly with RDS and provides a single interface to manage and create slave and read replica nodes that can run on Spot Instances.
