You have learned how to run containers on a single host with the local resources without the possibility of clustering our hardware resources in a way that allows us to uniformly use them as one big host. This has a lot of benefits, but the most obvious one is that we provide a middleware between developers and ops engineers that acts as a common language so that we don't need to go to the ops team and ask them for a machine of a given size. we just provide the definition of our service and the Docker clustering technology will take care of it.
