This reference architecture creates an AWS Service Catalog Portfolio called "Service Catalog EMR Reference Architecture" with one associated product. The AWS Service Catalog Product references a cloudformation template for the Amazon EMR cluster which can be launched by end users through AWS Service Catalog. The AWS Service Catalog EMR product creates an Amazon Elastic MapReduce cluster in the VPC and Subnets selected by the end user. A remote access security group is also created to allow for a bastion host to connect to the instances used by EMR via SSH.
