Cloud computing
is a new approach to software. It
offers benefits to businesses and customers
alike. In a cloud system, resources and products are
hosted in a central location. Businesses either host the
system on their own network servers or hire a company to
manage the resources. Customers can access the product from
anywhere over a standard Internet connection.
Typically customers who access these
public clouds
interact only with
a system’s
front end
software. They no longer deal with the more
complex
back end
implementation. Because many customers use a
single service, the costs are shared between them. Customers pay a
metered fee
, which covers only what they use. As a result, cloud
computing is usually less expensive for users.
Businesses may also want to implement internal cloud systems. They can
establish
private clouds
exclusively for their employees.
Community
clouds,
which share resources with other users, are another option. They
may even build
hybrid cloud
systems to permit complex interactions across
group boundaries.
Businesses will conclude that their investment in cloud computing is a good
one. Cloud services are designed to be flexible and long lasting. The
scalability
and
elasticity
of cloud computing makes it the right choice
for large or small businesses.
