Amazon has announced the availability of its Amazon Elastic Compute Cloud (EC2) I2 instances on its web services platform.
The storage-optimised high I/O instances, which are based on solid-state disk (SSD) technology, provide customers with higher random I/O performance and are touted to deliver more processing power due to the integration of Intel's Ivy Bridge EP processor, the Xeon E5-2670 v2.
"[The I2 instances] provide enhanced networking with lower latency, low jitter and very high packet-per-second performance, and are capable of delivering more than 365,000 random read input/output operations per second (IOPS) and more than 315,000 random write IOPS across eight 800GB SSD instance storage volumes," Amazon explained.
"With these capabilities, I2 instances are well suited for transactional systems, high-performance NoSQL databases like Cassandra and MongoDB, and other applications that benefit from very high disk I/O performance."
The firm said the update comes as customers were demanding more high I/O performance, but also wanted smaller instance size options for their smaller database fleets.
Amazon's EC2 vice president Matt Garman said: "I2 instances address these customer requests by enabling even better I/O performance, higher IOPS, more processing power, enhanced networking, and twice the memory of HI1 instances. Additionally, I2 instances come in more varied instance sizes than HI1 instances, ranging from 4 to 32 virtual CPUs."
Customers can launch I2 instances using the AWS Management Console, AWS Command Line Interface, AWS SDKs, and third-party libraries.
I2 instances are available in four instance sizes, with four, eight, 16, and 32 virtual CPUs, respectively. They are available in the US and Asia Pacific regions to begin with.
