Last week, Amazon announced the release of a new EC2 instance type for applications requiring fast access to big data. From the AWS site:
Customers whose applications require high sequential read and write performance over very large data sets can take advantage of the capabilities of this new Amazon EC2 instance type. High Storage instances are especially well suited for customers who use Hadoop, data warehouses, and parallel file systems to process and analyze large data sets in the AWS cloud. High Storage instances are currently available as a single instance type, Eight Extra Large (hs1.8xlarge) and provide customers with 35 EC2 Compute Units (ECUs) of compute capacity, 117 GiB of RAM, and 48 Terabytes of storage across 24 hard disk drives. hs1.8xlarge instances are capable of delivering more than 2.4 Gigabytes per second of sequential I/O performance.
