For the development of the eCommerce platform for, Argentina’s largest home appliance retailer chain, we have fully embraced Docker. Hence, I have studied about it, mainly Karl Matthias’ excellent Docker: Up and Running.

In its chapter on “The Path to Production Containers”, Karl states:

And about open source schedulers designed thay way, whereas Mesos currently implementing pessimistic concurrency:

I’ve begun exploring Nomad: in upcoming posts, I will share findings under way.

Till then !
