1. IOPS (input/output operations per second) is the standard unit of measurement for the maximum number of reads and writes to non-contiguous storage locations – IOPS is pronounced EYE-OPS.
2. IOPs is often measured with an open source network testing tool called an Iometer. Measuring both IOPS and latency can help a network administrators predict how much load a network can handle without performance being negatively affected.
3. Provisioned IOPS guarantee thousands of IOPS to users which increases performance for databases, distributed file systems and applications that require high I/O.
1. AWS has done a fourfold increase from the original Provisioned IOPS volume performance since last year’s launch.
2. We can now provision up to 4,000 IOPS and up to 1 TB of storage per Provisioned IOPS volume – no longer need to stripe (aka RAID 0) multiple volumes to reach the 4,000 IOPS performance level. If there is need for more performance, multiple EBS volumes can be created, each with Provisioned IOPS, and then stripe across them.
