all gibberish to me.
An old saw comes to mind: "If you can't baffle them with brilliance, befuddle them with bullshit".
That said, I'm not sure what this guy is trying to say either -- sure sounds impressive, though! Basically, it appears that amazon has more capital investment in 'cloud' services than many companies that are dedicated cloud infrastructure providers. Given their head-start and continuing lead in the field, that's not that surprising.
“Cloud” is marketing gibberish for “The hosted managed services you rejected in the 1990’s because we wouldn’t provide automatic failures and backups are rebranded as the “cloud” as we now include redundancy and backups.”
The “cloud” moniker came from Visio diagrams that depicted the Internet as a cloud. It really is a retarded concept.
