In my experience, for there to be widespread adoption and agreement over a concept, the semantics surrounding that concept must be unique and discrete. If the definition is too broad, there will be too much opportunity for dissenting opinion. NIST’s definition of cloud computing doesn’t really answer the mail when it comes to delivering a… Read More »
