# configuration of basic infrastructure
#
#
# appy is currently an Elastic Beanstalk-deployed Docker app, dependent upon a
# separate RDS instance.
#
# management of the project is principally performed via `manage` commands;
# (and, for consistency, a `manage stack` command covers this).
#
# terraform is here in use to replace manual configuration performed via the AWS
# Console, (and could perhaps be used to replace use of AWS CLI in `manage.py`,
# as desired/useful).
#
# NOTE: But, database could also, alternatively, be managed as part of Elastic
# Beanstalk (saved) configuration....
