    What is Cloud Computing
       
         Cloud computing is a technology that uses the internet and central 
       remote servers to maintain data and applications. 
       
         It provides on demand resources and services over the internet 
       with the power of scalability and reliability.
     Key Characteristics and Benefits
            Economy: 
               The most frequent reason cited was that the cloud wins in cost. 
               Zero Upfront Infrastructure Cost
               Pay as per Use
            Time: Just in time Infrastructure
            Elasticity : Scale up, scale down, on-demand – Improved Testability, 
             Experimentation
            Better Resource Utilization
            Potential for shrinking the Processing Time
            Overflow the traffic to Cloud
