Cloud computing

   Cloud computing is a form of computing mainly internet based, where shared resources, data andinformation are provided with computers and other devices when in demand. 
   It is a good example in which on-demand access to a shared pool of configurable computing resources are enabled. 


On-Demand Computing:
                                    Cloud computing is also popularly referred to as 'on-demand computing'. Cloud computing is related to the broader concept of converged infrastructure and shared services.                                            

                                  Cloud computing is a theoretical account in which convenient, on-demand network access to a shared pool of configurable computing resources are enabled so that they can be rapidly provisioned and released by the use of less amount of management effort.

Usage:
                  Cloud computing and storage solutions provide various opportunities to store and swear out their data in data centers for users and enterprises.                               It functions mainly on the sharing of resources to achieve coherence and economies of scale, similar to a utility over a net.
                  Advocates claim that cloud computing makes it easy for the enterprises to bring their applications up and running in

• lesser amount of time, with better manageability, 
• minimum maintenance issues, 
• enables IT to make quicker adjustments in terms of resources to meet the changing and 
• unpredictable business demand. 

                  Advocates also claim that cloud computing provides companies with opportunities to avoid upfront infrastructure costs and to lay focus on tasks that enhance their businesses instead of on infrastructure.
"Pay as you go" Model

                  Cloud providers typically utilize a "pay as you go" model. If the administrators are not able to accommodate to the cloud pricing model it may lead to unexpectedly high charges.

                  The present high-capacity network availability, computers and storage devices which are well within price range as well as the acceptance of hardware virtualization, architecture which is mainly service-oriented, and autonomic and utility computing have led to the rise in cloud computing.
               
                  Companies can scale up as computing demands increase and as the demand tends to decrease they will scale down.

Business Friendly

                  Cloud computing has in recent times grown up to be a service of high demand or utility due to the advantages which are present in high computing power, services with less costs, execution at a higher level and accessibility.

Fitfalls of Cloud Computing
                         
                  Anyhow, being in a state of infancy, it definitely has some pitfalls which need to
be given proper attention to provide growth to the user friendly nature of cloud computing.

                  There are privacy concerns regarding cloud computing because the service provider can access the information that is in the cloud at any time.
                         
                  Accidentally or intentionally alterations in data may occur.

                  Many cloud providers enjoy the freedom of sharing data with third parties if necessary for legal issues even without a guarantee.
                         
Terms & Conditions
                         
                  Privacy policies have the permission in which users have come to an agreement before they start using cloud services.  
                    
                  The solution to issues regarding privacy includes policy and legislation as well as end users' choices for how data is stacked away.

                  Users can have their information encrypted that are treated or stored inside the cloud to avoid unauthorized access.
