Reference Implementation of two API Gateways behind one custom domain, using ACM.
This is a quick implementation that was motivated because I wanted to figure it out. See also SAM #106
This repository represents two cloudformation stacks.
One stack is the core implementation and sets up the two API Gateways that proxy
to two Lambda Hello World functions (in us-west-1), for fun one is NodeJS and
one is Python. There is also a lambda for a custom cloudformation resource. At
this time, there is no CloudFormation resource available for a API Gateway
Custom Domain.
One stack sets up the ACM cert, only available in us-east-1 at this time.
If you want to test this yourself, change a few variables in Makefile and run make
API GW responds its own domain and the custom domain

I'm sure there are questions. I'll respond on GH issues as time allows.
