Amazon RDS Multi-AZ DB Clusters support new storage configurations
Database Blog
This article discusses new storage configurations available for Amazon RDS Multi-AZ DB Clusters. Previously, these clusters required Provisioned IOPS (io1) volumes, but now they also support General Purpose gp3 volumes and Provisioned IOPS io2 Block Express volumes.
Specifically, the article covers:
- Benefits of Amazon RDS gp3 volumes, including independent IOPS configuration and consistent performance under heavy load
- Benefits of Amazon RDS io2 Block Express volumes, such as higher storage durability and consistent sub-millisecond latencies
- Comparison of io1, io2, and gp3 volumes in terms of performance, latency, volume size limits, and maximum IOPS
- Recommendations for using io2 volumes for latency-sensitive workloads, io1 for regions without io2 support, and gp3 for workloads with fewer IOPS requirements
- The new storage options provide more flexibility and potentially lower costs for running Multi-AZ DB Clusters
