Cloud services are distinct in its makeup and are certainly different
from the more tradition al hosting process. With the cloud service
there is the leeway to sell on demand, which is usually by the minute
or hour, it is also elastic which means a user can dictate the amount of
service needed at any given time and the service is fully managed by
the provider.
This would effectively mean the customer would need nothing else
but a personal computer and access to the internet. Some of the
reasons cloud has become so popular is because this element is able
to provide significant innovations in virtualization and distributed
computing, while improving access to high speed internet..

Configured to be either private of public the cloud is able to switch
comfortably between the two while still providing the necessary
services on both sides.
The public cloud sell services to anyone on the internet while the
private cloud functions more as a proprietary network or data
centre that supplies hosted services to a limited group. However
the end goal of the cloud would be to provide easy, scalable access
to computing resources and IT services.
The infrastructure as a service allow a company to pay for only the
capacity needed and to only buy online as required. The platform
as a service is defined as a set of software and product
development tool that is hosted on the provider’s infrastructure.
The software as a service is where the vendor supplies the
hardware infrastructure, the software product and interacts with
the user through a front end portal..
