Cloud computing is where
the resources on the network
are not actually physical in
nature. They are provided to
the user virtually.
This can lead to a very fluid and dynamic environment as
required resources are normally only provisioned as needed
and are decommissioned once their use is done.
Most often, these virtual resources are not owned by the
company that uses them, but are provided by a service
provider.
While cloud computing is highly configurable and
changeable, it does have some basic structures that are
used in the classification of the type of cloud that is in use.

– Public cloud.
» Systems can interact with services and devices within the
public cloud and on public networks (e.g., the Internet)
and possibly other public clouds.
– Private cloud.
» Systems only communicate with services and devices
within the specified private cloud.
– Hybrid cloud.
» Combines aspects of both the public and private clouds.
– Community cloud.
» Cloud services used by private individuals, organizations,
or groups that have a common interest.

Because of the nature of
cloud computing, it is very
configurable to the needs
and desires of the purchaser.
Purchasers have many options beyond the type of
cloud services (e.g., public or private) that they want
to provision. They must also determine what type of
service they are going to require—from the most
basic to the highly complex (e.g., SaaS or PaaS).

– Software as a service (SaaS).
» The end user purchases the rights to use an application
(software) without the need to configure the virtual servers that
will deliver the application.
• It is usually delivered as a Web application (opened and used
from within a Web browser).
– Platform as a service (PaaS).
» The user is provided with a development platform for the
creation of software packages, without the need to configure
the virtual servers and infrastructure that delivers it.
– Infrastructure as a service (IaaS).
» The end user is provided with access to virtual servers
(configurable by the customer) and other virtual network
resources.
• Creates a highly configurable environment in which customers
can create the resources and performance that they require.
• The end user supplies the software that is going to be used on
the IaaS network.

It is not uncommon for the
type of cloud computing
being utilized by an
organization to be a mix.
Some departments may use IaaS, while a
development team utilizes a PaaS only. Part of the
advantage of cloud computing is only initializing
resources as they are needed.
In a private cloud situation, it is possible for the
organization that is using it to actually own the cloud
resources. If they do own the cloud resources, they
may have it on site, or they may pay to have the
resources hosted off site.

The use of cloud computing means that network resources are provided
virtually instead of physically. This can lead to a very dynamic and fluid
computing environment. The type of cloud deployed can be classified in one
of four ways: public, private, hybrid, or community.

Summary
The highly configurable nature of cloud computing has led to several
different types of cloud computing. In SaaS, only a software package is
provided (which is usually run from within a Web browser). PaaS provides a
development platform that is usually used in the creation of software
packages. With IaaS, the user configures the virtual network resources that
will be used—from virtual servers all the way down to the software
packages.
