Deployment of Clouds varies on the type of user groups, scale of
users using the clouds, constraints on the usage of resources, usage in
terms as internal and external activities within and outside
organizations.
I would like to put forth an anecdoe
on how tyre tubes evolved. The incident can be narrated as follows. In
late 18th century, a Doctor named Mr. Dunlop was busy with his research
and serving to his patients, but he was being troubled by the noise
generated by his son when he used to ride the bicycle.
This made Dr. Dunlop annoyed, to get rid of the sound generated by the tyre-less bicycle, he took the rubber hose and tied to the circumference of the bicycle iron-wheel, this brought him great relief and got rid of the unwanted noise. Later he came forward and applied this idea in mass generation of tubes for vehicle tyres. Thus now the world moves in air even on uneven land.
The
saying goes true that necessity is the mother of all inventions and
innovations. Private organizations built up clouds to evolve internal
solutions (private clouds) to manage the local infrastructure and the
amount of requests e.g. to ensure availability of highly requested data.
The computation varied according to the request generated. The
resources were not fully utilized all the time. This is due to the fact
that data centers initiating cloud capabilities made use of these
features for internal purposes. Later the organizations extended the
interests by considering selling the capabilities publicly (public
clouds). This brought the providers gain confidence in publication and
exposition of cloud features. This movement from private via public to
combined solutions is often considered a “natural” evolution of Hybrid
systems, though there is no reason for providers to not start up with
hybrid solutions, once the necessary technologies have reached a mature
enough position.
We can hence distinguish between the following types of deployment of Clouds [2]:
i. Private Clouds
ii. Public Clouds
iii. Hybrid Clouds
iv. Community Clouds
