Cloud computing provides the facility to provision virtual
hardware, runtime environment and services to a person having money.
These all things can be used as long as they are needed by
the user, there is no requirement for the upfront commitment.
The whole collection of computing system is transformed into
a collection of utilities, which can be provisioned and composed together to
deploy systems in hours rather than days, with no maintenance costs.
The long term vision of a cloud computing is that IT
services are traded as utilities in an open market without technological and
legal barriers.
In the near future we can imagine that it will be possible
to find the solution that matches with our requirements by simply entering our
request in a global digital market that trades with cloud computing services.
The existence of such market will enable the automation of
the discovery process and its integration into its existing software systems.
Due to the existence of a global platform for trading cloud
services will also help service providers to potentially increase their
revenue.
A cloud provider can also become a consumer of a competitor
service in order to fulfill its promises to customers.
