To convert an existing AWS EC2-classic infrastructure into a VPC orientated architecture. We need a multi-subnet (public and private) arrangement for web-servers, RDS instances and application/worker servers. Security groups, firewall, route tables etc need be set up according to server/subnet requirements e.g. application servers within the private subnet should not be internet accessible (further details to be supplied).
