The internal infrastructure of AWS apps are fairly guessable anyway. There are only a limited number of AWS resources and they fit together in predictable ways, VPC - Gateway - ASG - EC2 etc etc.
I think it's really great that they've talked about this, it's quite rare to hear about these kinds of internal migrations, and it's something I do a lot with clients but it's not really glamorous enough to talk about.
Hi KurtMueller, get yourself a new AWS account with the free tier, find out exactly which resources ARE NOT included with the free tier, and get down with a simple Terraform file. Terraform code has a one-to-one mapping with AWS resources, so it's easy to follow. One code test that my previous company had was to create a simple load-balanced web server in Ansible or Chef, but you could also do it with Terraform too. Two servers and a load balancer in front, simple but teaches you a lot of fundamental stuff.
Forgive the self promotion but I'm building a subscription video site - http://stackleap.com/ - to teach people how to build and deploy to AWS infrastructure.
The difference between StackLeap and sites like acloud.guru is that I'm focussing on the day to day stuff rather than high level concepts you need to know to pass the certification exams.
I'm hoping to launch a beta in the next few weeks.
I've been very impressed with CloudAcademy - it seems to issue AWS accounts per course/per lab - it guides you through the steps and check whether you completed them by checking the AWS account, and then tears it down at the end.
You might not be ready for that level of integration, but see if you can get a demo or trial.
