CLOUD COMPUTING; NEW AGE OF TECHNOLOGY INNOVATION: A COMPREHENSIVE STUDY

Cloud computing is the development of parallel computing, distributed computing, grid computing and virtualization technologies that define the shape of a new era. Cloud computing is an emerging model of business computing. Cloud computing has formed the conceptual and infrastructural basis for tomorrow is computing. The global computing infrastructure is rapidly moving towards cloudbased architecture. While it is important to take advantages of could based computing by means of deploying it in diversified sectors, the security aspects in a cloud based computing environment remains at the core of interest. Cloud based services and service providers are being evolved which has resulted in a new business trend based on cloud technology. With the introduction of numerous clouds based services and geographically dispersed cloud service providers, sensitive information of different entities are normally stored in remote servers and locations with the possibilities of being exposed to unwanted parties in situations where the cloud servers storing those information are compromised. If security is not robust and consistent, the flexibility and advantages that cloud computing has to offer will have little credibility. Technology innovation and its adoption are two critical successful factors for any business/organization. Cloud computing is a recent technology paradigm that enables organizations or individuals to share various services in a seamless and costeffective manner. This paper describes cloud computing, a computing platform for the next generation of the Internet. The paper defines clouds, types of cloud Provides, Comparison of Cloud Computing with Grid Computing, applications and concerns of Cloud Computing , Concept of Virtualization in Cloud Computing.
