A Performance Centric Introduction to Cloud Computing

Cloud computing refers to Internet based development and utilization of computer technology. It is a style of computing, in which dynamically scalable (and often virtualized) resources are provided as a service over the Internet. The concepts behind cloud computing incorporate Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), and Infrastructure-as-a-Service (IaaS), respectively. In today’s rather challenging economical environment, the promise of reduced operational expenditure, green computing advantages, along with more reliable, flexible and scalable application services made cloud computing a rather sought-after technology.
