A toy example demonstrating microservices
The bootstrap.sh script creates a S3 bucket to store packaged cloud-formation templates.
The deploy.sh script deploys the nested stacks by first retrieving the bucket name from the bootstrap stack, then
running aws cloudformation package to convert local templates into package.yaml a template with the
local names replaced by their S3 locations. Finally, it runs aws cloudformation deploy package.yaml to
deploy the nested stacks.
