Amazon Doubles IOPS of Elastic Block Store
Amazon recently told its customers of the Elastic Block Store (EBS) that they can now provision up to 2,000 IOPS (Input/Output Operations Per Second) per EBS volume, up from 1,000 IOPS before.
"This is an order of magnitude more IOPS than you can expect from a high-end 15,000 RPM disk drive," Amazon wrote in a blog post. "If you've been RAIDing multiple volumes together for even higher performance, you may be able to achieve the desired level of performance with far fewer volumes."
Amazon said that EBS will deliver within 10 percent of the provisioned IOPS performance 99.9% over the lifetime of a respective volume.
To achieve even higher IOPS, customers can combine multiple provisioned volumes together to make an EC2 application more responsive and cater to the needs of I/O-focused loads such as database storage or transaction processing. According to the company, SAP provisioned environments of more than 20,000 IOPS. Amazon said that customers can also request the launch of EBS Optimized EC2 instances with data throughputs ranging from 500 to 1000 Mbps.
The Amazon EBS supports storage volumes between 1 GB and 1 TB that can be mounted as devices by EC2 instances. EBS provisioned IOPS volumes pricing starts at $0.125 per GB-month of provisioned storage and $0.10 per provisioned IOPS-month.
