# Amazon MQ can only be set up in a VPC (created in vpc.yml). However, all
# the other services are running on EC2-Classic, and it's impossible for
# security groups to filter traffic between EC2-VPC and EC2-Classic.
#
# One solution is to leave Amazon MQ accessible on the public internet and
# use credentials for controlling access. We don't want to go this way
# because it's one more set of credentials to maintain.
