Geez, you've got a long memory.....
IMHO, Cloud is a term that is being used by every vendor who possible
can, to show that they are up with the current trend. There is much
confusion in the ICT industry because Cloud is being used as a
shorthand, and leaves a lot unsaid. It's referred to as cloud-washing.
Using Cloud as an adjective helps considerably.
Cloud technology is mainly virtualisation, server and data
virtualisation being the main ones. Anyone can use virtualisation and
many ICT do. There are lots of vendors selling cloud technology, some to
IT departments, some to purveyors of Cloud services
Cloud services are being sold by those who own lots of technology and
who are making access available on a services basis. A bit lit a car
owner offering taxi services. The car is still car, it's just
accessible in small lots.
NIST, whose definition seems to be quoted the most, define Cloud as a
procurement mechanism, not as a technology.
So, in summary, Cloud services is a way of using a someone else's
technology on an as needed basis and paying for it as such. All Cloud
services issues are related to the fact that it's not your technology
you are using, it's someone else's.
If you implement your own Cloud technology, many of these issues go
away. And if you implement your own Cloud technology and call it a
private cloud (as in the case of Navitaire), then it's not Cloud
services. It's more like cloud-washing. The test is in how you pay for it.
The government is well aware of these differences, it remains to be seen
if Australian industry is as well informed.
