Fast Forward – Provisioned IOPS for EBS Volumes

The I/O Imperative
Every bit I noted earlier this calendar month, modern spider web and mobile applications are highly I/O dependent, storing and retrieving lots of data in order to evangelize a rich and personalized experience.

In order to give you lot the I/O performance and the flexibility that y'all need to build these types of applications, we've released several new offerings in the final few months:

  • For seamless, managed, scaling of NoSQL workloads, we recently introduced DynamoDB, an SSD-backed NoSQL database with read and write times measured in single-digit milliseconds, with very small-scale variance from request to request. DynamoDB makes it easy to scale up from xx to 200,000 or more reads and writes per second and to scale back down over again based on your application's requirements. The response to DynamoDB has been incredible, and it has become (as Werner noted) our fastest-growing service.
  • Ii weeks ago, we launched the first member of the EC2 Loftier I/O family unit,  the h1.4xlarge instance type, to back up time serial analysis, NoSQL databases, and mobile and streaming applications requiring low latency access to storage systems delivering tens of thousands of IOPS.  The h1.4xlarge comes with 2 TB of SSD-backed storage on each case.

We know that you lot desire more options for your I/O intensive applications, and nosotros're happy to oblige.

Here You Go

What Are IOPS?

As you may know, the performance of a block storage device is usually measured and quoted in a unit called IOPS, short for Input/Output Operations Per 2d.

To put the numbers in this post into perspective, a disk drive spinning at 7,200 RPM tin can perform at 75 to 100 IOPS whereas a drive spinning at 15,000 RPM will deliver 175 to 210. The exact number will depend on a number of factors including the admission pattern (random or sequential) and the corporeality of data transferred per read or write functioning. Nosotros are focusing on improving the operation and consistency of database-backed applications that run on AWS by adding new EBS and EC2 options.

Hither's what we are announcing today:

  1. A new type of EBS volume chosen Provisioned IOPS that gives you the ability to dial in the level of performance that y'all demand (currently up to 1,000 IOPS per volume, with more coming presently). You can stripe (RAID 0) ii or more volumes together in lodge to reach multiple thousands of IOPS.
  2. The ability to launch EBS-Optimized instances which feature dedicated throughput between these instances and EBS volumes.

EBS Provisioned IOPS
We released EBS in the summer of 2008. Since that time, our customers have very successfully used EBS to store the persistent data associated with their EC2 instances. We take found that there are certain workloads that require highly consequent IOPS, and others that require more IOPS on an absolute basis. Relational databases certainly qualify on both counts.

As a point of reference, a standard EBS volume will by and large provide about 100 IOPS on average, with the power to burst to hundreds of IOPS on a all-time-try basis. Standard EBS volumes are bully for applications with moderate or bursty I/O requirements as well as for boot volumes.

The new Provisioned IOPS EBS volume allows y'all to set the level of throughput that you lot demand, and currently supports upwardly to 1,000 IOPS (for 16K), with higher limits coming soon. For even college performance, y'all can stripe multiple Provisioned IOPS volumes together, giving you the ability to evangelize thousands of IOPS per logical volume to your EC2-powered awarding. These volumes deliver consistent operation and are well-suited to database storage, transaction processing, and other heavy random I/O loads. When fastened to EBS-Optimized instances, these volumes are designed to deliver inside x% of their provisioned I/O functioning 99.9% of the time.

You can create Provisioned IOPS EBS volumes from the AWS Management Console, the command line tools, or via the EC2 APIs. If you apply the console, yous need but select the Provisioned IOPS volume type and so enter the desired number of IOPS:

Provisioned IOPS volumes are priced at $0.125 per GB of allocated storage per month plus $0.ten per provisioned IOPS per calendar month in Usa East (Northern Virginia); see the EBS folio for more info. Past default, each AWS account tin can create up to 20 TB of Provisioned IOPS volumes with a full of ten,000 IOPS. If you need more of either (or both), simply fill out this form.

You can create a provisioned equivalent of your existing EBS volume by suspending all I/O to your volume, creating a snapshot, and so creating a Provisioned IOPS volume using the snapshot as a starting signal.

EBS-Optimized EC2 Instances
For maximum performance and to fully apply the IOPS provisioned on an EBS book, yous can now request the launch of EBS Optimized EC2 instances. An EBS-Optimized instance is provisioned with dedicated throughput to EBS. The m1.big, m1.xlarge, and m2.4xlarge instance types are currently available as EBS-Optimized instances. m1.large instances can transfer data to and from EBS at a charge per unit of 500 Mbit/second; m1.xlarge and m2.4xlarge instances can transfer data at a charge per unit of m Mbit/second. This is additional throughput, and doesn't affect other general purpose network throughput already available on the instance.

There is an boosted hourly charge for the EBS-Optimized instances: $0.025 for the m1.big and $0.05 for the m1.xlarge and m2.4xlarge instance types.

You tin can upgrade your EC2 instances to EBS-Optimized instances as follows:

  1. Close downward any applications that are running on the instance.
  2. Stop the example.
  3. Modify the instance using the ec2-alter-instance-attribute command) and set the EBS-Optimized flag. Change the example blazon to i of the supported instance types if necessary.
  4. Start the instances

And Here'south Arun
I spoke with Arun Sundaram, a Production Manager on the AWS Storage team, to learn more virtually these two features. Here'due south what he had to say:

And That'due south That
These new features are bachelor for yous to use today. Requite them a whirl, and let me know what you think!
