- Start up four AWS instances configured for clustering via the Puppet script
Each server has the following configuration
Code Block aws_region = us-east-1 aws_ami = ami-e995e380 aws_instance_type = m1.large aws_block_device_mapping = '/dev/sda1=:10::io1:100' aws_ebs_optimized = true

- Once the cluster has been established, an Elastic Load Balancer was configured over the four instances.
