I like this definition because while it's still broad, it focuses on
essential characteristics which distinguish cloud computing from datacenter
virtualization in general and from "it's on the Internet!"
Yeah, the NIST definition is fairly well accepted.
If I haven't lost you already, I encourage you to read the
definition.
Really, it's short. But if you're hanging on by an attention-span thread,
the essentials are:
- On demand self-service.
- Broad network access.
- Resource pooling.
- Rapid elasticity.
- Measured service.
That's a good summary. I often say "on-demand, self-sevice,
pay-as-you-go and the illusion of infinite capacity".
