IaaS Cloud Litmus Test – The Five Minute VM
Cloud is an operating model supported by technology

I will make this simple. There is only one question you need to ask yourself or your IT department to determine if what you have is really an Infrastructure-as-a-Service cloud.
Perhaps a little bit more detailed?
If you can answer yes, congratulations – it’s very likely a cloud. If you cannot answer yes it is NOT cloud IaaS. There is no wriggle room here.
Cloud is an operating model supported by technology. And that operating model has as its core defining characteristic the ability to request and receive resources in real-time, on-demand. All of the other NIST characteristics are great, but no amount of metering (measured service), resource pooling, elasticity, or broad network access (aka Internet) can overcome a 3-week (or worse) provisioning cycle for a set of VMs.
Tie this to your business drivers for cloud.
Does that thing you call a cloud give you a 5 Minute VM? If not, stop calling it a cloud and get serious about building the IT Factory of the Future.
