New – Launch Amazon EMR Clusters in Private Subnets
oday we are announcing that Amazon EMR now supports launching clusters in Amazon Virtual Private Cloud (VPC) private subnets, allowing you to quickly, cost-effectively, and securely create fully configured clusters with Hadoop ecosystem applications, Spark, and Presto in the subnet of your choice. With Amazon EMR release 4.2.0 and later, you can launch your clusters in a private subnet with no public IP addresses or attached Internet gateway. You can create a private endpoint for Amazon S3 in your subnet to give your Amazon EMR cluster direct access to data in S3, and optionally create a Network Address Translation (NAT) instance for your cluster to interact with other AWS services, like Amazon DynamoDB and AWS Key Management Service (KMS). For more information on Amazon EMR in VPC, visit the Amazon EMR documentation.
