Basics – Docker, Containers, Hypervisors, CoreOS

This week it was rebranded as "vCloud Air Network" and that is too much of a mouthful to keep saying as well. Don't these marketing people live in the real world ? Lets me share my suggestion .......

Blame the System For Resisting Change – Not The People
I often hear vendors and pundits proclaim that Enterprise is resisting change. In particular, they say that individuals in Enterprises can't see the change or won't discuss buying new technology. I see these objections as failure of the current system and much less due to the people.
