“Cloud computing is Internet- (“cloud-”) based development and use of computer technology (“computing”). In concept, it is a paradigm shift whereby details are abstracted from the users who no longer need knowledge of, expertise in, or control over the technology infrastructure “in the cloud” that supports them. Cloud computing describes a new supplement, consumption and delivery model for IT services based on Internet, and it typically involves the provision of dynamically scalable and often virtualized resources as a service over the Internet.”
“In general, cloud computing customers do not own the physical infrastructure, instead avoiding capital expenditure by renting usage from a third-party provider. They consume resources as a service and pay only for resources that they use. Many cloud-computing offerings employ the utility computing model, which is analogous to how traditional utility services (such as electricity) are consumed, whereas others bill on a subscription basis. Sharing “perishable and intangible” computing power among multiple tenants can improve utilization rates, as servers are not unnecessarily left idle (which can reduce costs significantly while increasing the speed of application development). A side-effect of this approach is that overall computer usage rises dramatically, as customers do not have to engineer for peak load limits. In addition, “increased high-speed bandwidth” makes it possible to receive the same response times from centralized infrastructure at other sites.”

SMS എന്താണെന്ന് പണ്ട് ബോസ് സെമിനാര് എടുത്ത് SMS എന്ന പരിപാടിയെ തന്നെ വെറുത്തു പോയതാ.. അത് പോലെ ആകുമോ cloud computing um..
