Will Containers Bring about a Smaller Shoe Size?

Will containers change the shoe size of the physical servers in the datacenter? When having a conversation with some of my peers about containers in general, the discussion started to move in a direction of what containers can bring to the environment and as such what steps or changes would be needed to be implemented to make the environment to be able to bring about the greatest success when offering containers as an option to the customers. To truly understand the change in thinking about the physical server’s footprint size I first need to make sure that we have a basic understanding of what the difference is between virtualization as a general term and container virtualization.
