By means of those name, SprawlDeck plays as a service deck, while SprawlRoulette picks one from many service decks every time when it takes a request.
SprawlDeck will give a random number to SprawlRoulette when it's ready to serve. Then SprawlRoulette may pass a request object to that SprawlDeck for processing the request.
The package can be installed by adding sprawl_deck to your list of
dependencies in mix.exs:
def deps do
[
{:sprawl_deck, ">= 1.0.0", path: "../sprawl_deck"}
]
