You can now launch Amazon EMR clusters on the next generation of Amazon EC2 Dense-storage (D2) instances. D2 instances allow you to take advantage of the low cost, high disk throughput and high sequential I/O access rates offered by these instances. Workloads that rely on data stored in the Hadoop Distributed File System (HDFS) will benefit from the low cost per terabyte offered by D2 instances.
Amazon EMR allows you to use both HDFS, installed on instance storage, and Amazon S3 as your primary data store. Amazon EMR clusters have pre-configured defaults set for Hadoop 1.x and 2.x, to optimize performance for most workloads. You can also change these defaults using bootstrap actions.
D2 instances are available in four sizes with 6TB, 12TB, 24TB, and 48TB storage options. To learn more about the D2 instances, please visit the Amazon EC2 Instance page. Amazon EMR supports D2 instances in all regions where they are available: US East (Northern Virginia), US West (Oregon), EU (Ireland, Frankfurt), and Asia Pacific (Tokyo, Singapore, Sydney) regions.
