# Product in DB vs. product in code
# DB:
# - need to define params (+param types) in db -> messy?
# - get /products/ is easy / automatic
#
# code
# - can have serializer/verification of fields easily in DRF
# - can have per product side effects / extra code running
# - might (??) make features easier??
# - how to setup / query the recurring period (?)
# - could get products list via getattr() + re ...Product() classes
# -> this could include the url for ordering => /order/vm_snapshot (params)
# ---> this would work with urlpatterns
# Combination: create specific product in DB (?)
# - a table per product (?) with 1 entry?
# Orders
# define state in DB
# select a price from a product => product might change, order stays
# params:
# - the product uuid or name (?) => productuuid
# - the product parameters => for each feature

# logs
