Cloud Computing
Cloud computing refers to availability of dynamically scalable IT
enabled capabilities (hardware and software) from third party vendors
over a network. The keyword here is 'dynamically scalable'. In simple
terms, what this means is that you can ramp up or ramp down these third
party resources as and when needed. The physical hardware / software may
reside on different machines / networks across different geographical
locations. Cloud computing provides services like infrastructure,
software, storage and even the OS platform as a service. Typically,
these services are accessed over the Internet. Different cloud providers
have developed various access models to these services. While large
companies can afford to establish and run their own capabilities, it is
not practical for small and medium sized players.
The
cloud model differs from traditional outsourcing in that customers do
not hand over their own IT resources to be managed. Instead they plug
into the cloud, treating it as they would an internal data center or
computer providing the same functions.
Cloud computing can be an effective strategy to reduce the IT operations and management costs of a company.
Cloud Computing Technology
Cloud
computing has been made possible because of recent development in web
technology. At the communication level, it has been made possible due to
the development of protocols like http, SOAP, XML and REST.
Essentially, these technologies allow various programs to talk to each
other. At the infrastructure level, cloud computing is based
amalgamation of many other concepts like on virtualization and grid
computing. These advances have made it possible for several machines,
which physically might be (and generally are) miles away act in a
seamless fashion.
Benefits of Cloud Computing
include reduced infrastructure costs. Since cloud computing works over a
network, the downside is the security threat due to less data control. .
