Amazon Web Services introduced on Tuesday a beefed-up virtual machine instance for running data-intensive workloads.
The new D2 instances offer dense, high-performance storage and fast networking for users churning through large amounts of data in the cloud, said Jeff Barr, chief evangelist for Amazon's cloud, in a blog post.
D2 makes sense for customers processing multi-terabyte data sets of the kind encountered when working with MapReduce and Hadoop clusters.
For more rapidly accessing and processing warehoused data, D2 adds memory and computing speed to HS1, the first-generation of Amazon's high storage density and performance instances.
D2 comes in four tiers -- the lowest offering four virtual CPUs and 30.5 GBs of RAM, and the highest 36 virtual processors and 244 GBs of RAM. Moving up in tier, the instances take on higher network speed and disk throughput, with the top tier, d2.8xlarge, running on a 10-Gbps network with 3,500-MBs-per-second read speed and 3,199-MBs-per-second write speed when launched with a Linux Amazon Machine Image.
"The storage on this instance family is local, and has a lifetime equal to that of the instance. Therefore, you should think of these instances as building blocks that you can use to build a complete storage system," Barr said.
