Amazon Web Services (AWS) has enhanced and added new features around solid state drive (SSD) storage. The public cloud provider has boosted the performance of Provisioned IOPS (SSD) and General Purpose (SSD) EBS volumes.
This announcement follows on the company’s June news regarding the launch of SSD-backed Elastic Block Storage (EBS), which was launched in all AWS regions. Jeff Barr, chief evangelist for Amazon Web Services, wrote in a blog post that Amazon expected the SSD EBS volumes to be of interest to customers, but the company was surprised at just how popular they would be.
It’s now one of the fastest-adopted services in Amazon’s history, he noted. So it makes sense that Amazon is beefing up the features around its SSD-based offerings.
And in this case, it’s throughput that is getting an upgrade. Amazon has improved the data transfer rates of both General Purpose (SSD) and Provisioned IOPS (SSD) EBS volumes. The improvements include:
Amazon has doubled the maximum attainable throughput to each volume. Both can now sustain up to 128MBps of read or write traffic.
An I/O request of up to 256KB is now counted as a single I/O operation, which Barr noted makes it up to 16 times as cost-effective and performant as before. Each IOP was limited to 16 KB of data transfer prior to this enhancement. By attaching volumes to a single c3.8xlarge EC2 instance, customerscan achieve up to 800MBps of aggregate throughput per instance.
“These changes will improve your I/O performance and can also dramatically reduce your storage costs. If your application has a need for 128 megabytes per second of data transfer, you can now meet this need by provisioning 500 IOPS instead of 8000 IOPS,” Barr wrote.
The throughput enhancement has been rolled out to all AWS regions.
