Provisioned IOPS

For any production application that requires fast and consistent I/O performance, we recommend Provisioned IOPS (input/output operations per second) storage.

Provisioned IOPS storage is a storage option that delivers fast, predictable,and consistent throughput performance. When you create a DB instance, you specify an IOPS rate and storage space allocation. Amazon RDS provisions that IOPS rate and storage for the lifetime of the DB instance or until you change it. Provisioned IOPS storage is optimized for I/O intensive, online transaction processing (OLTP) workloads that have consistent performance requirements.


A virtual private cloud is a virtual network that is logically isolated from other virtual networks in the AWS cloud. Amazon Virtual Private Cloud (VPC) lets you launch AWS resources, such as an Amazon RDS or Amazon EC2 instance, into a VPC. The VPC can either be a default VPC that comes with your account or it could be one that you create. All VPCs are associated with your AWS account.


IOPS is available for all your RDS instances it is not depend on which database engine or their deployment strategy (either inside VPC or outside VPC). You can provision a MySQL, PostgreSQL, or Oracle DB instance with up to 30,000 IOPS and 3 TB of allocated storage. You can provision a SQL Server DB instance with up to 10,000 IOPS and 1 TB of allocated storage.


Using Provisioned IOPS Storage with Multi-AZ, Read Replicas, Snapshots, VPC, and DB Instance Classes

For production OLTP use cases, we recommend that you use Multi-AZ deployments for enhanced fault tolerance and Provisioned IOPS storage for fast and predictable performance.
