So orchestration is going to become easier...?
Good analysis here by Joe Emison.He differentiates containers as well as anyone who's taken on the task. Yes, containers resemble a file built to run as a virtual machine, only it runs as its own thing in a defined memory space under Linux. My words, not Joe's. He said: "With encapsulation and Docker, you build a Linux container (sort of like a binary meant to run on a software virtual machine) that runs your application." There are advantages, either way, container vs. virtual machine, but cloud workloads are likely to become increasingly containerized.

Orchestration pre-requisites
Orchestration is a tough, holy grail domain.   Remember the hype about service orchestration?  Orchestration requires defining atomic units, dependencies, and interaction rules.  Recent advancements in containerization are good, yet network dependencies need to be read from the docker configuration file.  Also, docker provides 'links' to define relationships between containers, yet the links are not readily externalized outside the host machine. Also, docker by itself does not scale across multiple host machines, nor define what is inside the container.

 

A PaaS extending docker with enterprise-ready orchestration and application lifecycle management capabilities is required.

Re: Orchestration pre-requisites
Very good summary - orchestration is not a trivial task and far more than just running script remotely. It needs a comprehensive framework to accomplish the necessary task. Docker is a good start but as you pointed out, there is still further way to go.
