I have been in this crazy cloud space for ages. Too long to 'fess up to. And for as long as there has been cloud, the dream of hybrid cloud has existed.
It's a glitter-covered world in which a flexible, self-service, charge back-driven cloud lives in your own data center with a shiny new bi-directional pipe to one or more public clouds, where flexible on-demand resources also exist. It smells of cotton candy and hope.
