Amazon Introduces High I/O SSD-backed EC2 Instances

Jeff Barr:

In order to meet this need, we are introducing a new family of EC2 instances1 that are designed to run low-latency, I/O-intensive applications, and are an exceptionally good host for NoSQL databases such as Cassandra and MongoDB.

Many complains about running databases on EC2 instances were about the I/O. I guess Amazon has been hearing this loud and clear.


  1. Specs of the new EC2 instace: 

    • 8 virtual cores (35 ECU)
    • HVM and PVM virtualization.
    • 60.5 GB of RAM.
    • 10 Gigabit Ethernet connectivity with support for cluster placement groups.
    • 2 TB of local SSD-backed storage, visible as a pair of 1 TB volumes.
