Pontos positivos • Mesmo ambiente em dev e prod •
Dependências facilmente atualizadas • Leve e rápido • Possibilidade de compor containers

Pontos negativos • APIs mudam muito rápido • Conceito de
containers é difícil de entender • Comandos muito extensos, difícil memorização

Vagrant x Docker • Vagrant + Provisionamento é difícil de
atualizar • Containers são bem mais leves e com boot mais rápido
