Cloud computing is a recent paradigm based around the notion of delivery of resources via a service model over the Internet. Despite being a new paradigm of computation, cloud computing owes its origins to a number of previous paradigms. The term cloud computing is well defined and no longer merits rigorous taxonomies to furnish a definition. Instead this survey paper considers the past, presen...

s Cloud computing moved away from personal computers and the individual enterprise application server to services provided by the cloud of computers. The emergence of cloud computing has made a tremendous impact on the Information Technology (IT) industry over the past few years. Currently IT industry needs Cloud computing services to provide best opportunities to real world. Cloud computing is...

Cloud computing is one of the today’s most exciting technology because of its cost-reducing associated with computing while increasing flexibility and scalability for computer processes. In the past few years, cloud computing has growing from being a promising business idea to one of the fastest growing parts of the IT industry. Even there are great benefits to be gained from cloud computing, i...

Cryptography is a key element in establishing trust and enabling services the digital world. It represented ways that are not accessible to human users. Hence, humans left out security necessary modern communication protocols many services. A primitive or protocol should be defined reach goal. Beside introduction part this paper represents types of cryptography, algorithm cryptography technique...

Cloud computing is an emerging concept combining many fields of computing Cloud computing will play a major role in the Internet of Services, enabling on-demand provisioning of applications, platforms, and computing infrastructures.. The foundation of cloud computing is the delivery of services, software and processing capacity over the Internet, reducing cost, increasing storage, automating sy...

Cloud computing is an evolving utility computing mechanism in which cloud consumer can detect, choose and utilize the resources (infrastructure, software and platform) and provide service to user based on pay per use model as computing utilities. Current computing mechanism is effective, particular for medium and small cloud based companies, in which it permits easy and reliable access to cloud...

Cloud computing has elevated IT to newer limits by offering the market environment data storage and capacity with flexible scalable computing processing power to match elastic demand and supply, whilst reducing capital expenditure. However the opportunity cost of the successful implementation of Cloud computing is to effectively manage the security in the cloud applications. Security consciousn...
