Managing multiple containers and connecting them is known as orchestrating them. Microservices that are deployed in containers will have to orchestrate them to be sure that the multiple microservices are interconnecting.

This concept includes details such as discovering where the other containers are, dependencies between services, and generating multiple copies of the same container.
