Before the official announcement for this deployment, if you wanted to deploy your SPA app, along with your other serverless services, to try it out, in the /example directory, run:
make deploy STACK_NAME=<name of cf stack> BUCKET_NAME=<s3 cloudformation deployment bucket>
For an explanation of how this works, check out the example template.yml
Note: If you change your frontend folder from the current web-site into something else, be sure to replace it in its template.yml SiteSource, property CodeUri.
