Provisioned IOPS (PIOPS)

Storage performance option where a specific number of I/O operations per second is purchased and guaranteed for a volume.

Definition

Provisioned IOPS lets customers specify the IOPS a volume or database storage must deliver, independent of capacity, for predictable low-latency performance. It is offered on EBS io1/io2 and gp3, Amazon RDS storage, Azure Premium SSD v2 and Ultra Disk, and similar services.

Example

An RDS SQL Server instance is configured with 20,000 provisioned IOPS for a transaction-heavy ERP system.

Exam tip

When a scenario needs consistent I/O performance for a database, choose provisioned IOPS rather than larger general-purpose volumes.
