Create a 6-instance architecture like our current one so we can migrate Science. Like:
AMI OS: Ubuntu Server 12.04 LTS
SSH KEY: wp-science-east.pem
Security Group: WP-SCIENCE-EAST (allow ssh, http, https)
AZ=US-EAST-1a AZ=US-EAST-1b Instance type
science-app-left science-app-right m1.medium (4GB RAM)
science-adm-left science-adm-right m1.medium (4GB RAM)
science-db-left science-db-right m1.large (8GB RAM)Then front with Elastic Load Balancer.
Finally serve via CloudFront CDN targetting the United States.
