If you use private subnets, the nat gateway is not cheap - £30 a month. You dont need the nat gateway, you can achieve the same thing with security groups (block all incoming) (explained <https://www.reddit.com/r/aws/comments/75bjei/private_subnets_nats_vs_simply_only_allowing/>). Advantage to NAT is all outgoing requests to the internet come from a single IP.
Summarise the flow -> VPC, internet gateway, attachment + route tables, subnets etc. Mention the nat gateway but show how it can be replaced with security groups.
Merge the CF templates into one, make sure all the importing and other s nippets are documented.
