We launched EBS Volumes with Provisioned IOPS method again in 2012. These volumes are an awesome match in your most I/O-hungry and latency-sensitive functions as a result of you possibly can dial within the degree of efficiency that you just want, after which (with the launch of Elastic Volumes in 2017) change it later.

Over time, now we have elevated the ratio of IOPS per gibibyte (GiB) of SSD-backed storage a number of occasions, most not too long ago in August 2016. This ratio began out at 10 IOPS per GiB, and has grown steadily to 50 IOPS per GiB. In different phrases, the larger the EBS quantity, the extra IOPS it may be provisioned to ship, with a per-volume higher certain of 64,000 IOPS. This alteration in ratios has diminished storage prices by an element of 5 for throughput-centric workloads.

Additionally, based mostly in your requests and your insatiable need for extra efficiency, now we have raised the utmost variety of IOPS per EBS quantity a number of occasions:

The August, 2014 change within the I/O request dimension made EBS 16x cheaper for throughput-centric workloads.

Bringing the varied numbers collectively, you possibly can consider Provisioned IOPS volumes as being outlined by capability, IOPS, and the ratio of IOPS per GiB. You must also take into consideration sturdiness, which is expressed in share phrases. For instance, io1 volumes are designed to ship 99.9% sturdiness, which is 20x extra dependable than typical commodity disk drives.

Larger Sturdiness & Extra IOPS
At the moment we’re launching the io2 quantity sort, with two vital advantages, on the similar worth as the present io1 volumes:

Larger Sturdiness – The io2 volumes are designed to ship 99.999% sturdiness, making them 2000x extra dependable than a commodity disk drive, additional lowering the opportunity of a storage quantity failure and serving to to enhance the provision of your utility. By the best way, prior to now we expressed sturdiness by way of an Annual Failure Charge, or AFR. The brand new, percentage-based mannequin is in keeping with our different storage choices, and likewise communicates expectations for fulfillment, relatively than for failure.

Extra IOPS – We’re rising the IOPS per GiB ratio but once more, this time to 500 IOPS per GiB. You will get larger efficiency out of your EBS volumes, and you may scale back or outright get rid of any over-provisioning that you just might need accomplished prior to now to realize the specified degree of efficiency.

Taken collectively, these advantages make io2 volumes an ideal match in your high-performance, business-critical databases and workloads. This consists of SAP HANA, Microsoft SQL Server, and IBM DB2.

You may create new io2 volumes and you may simply change the kind of an current quantity to io2:


$aws ec2 modify-volume --volume-id vol-0b3c663aeca5aabb7 --volume-type io2

io2 volumes assist all options of io1 volumes except for Multi-Attach, which is on the roadmap.

Out there Now
You may make use of io2 volumes within the US East (Ohio), US East (N. Virginia), US West (N. California), Canada (Central), Europe (Frankfurt), Europe (Eire), Europe (London), Europe (Stockholm), Asia Pacific (Hong Kong), Asia Pacific (Mumbai), Asia Pacific (Seoul), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), and Center East (Bahrain) Areas at the moment.
