Cloud computing systems fundamentally provide access to large pools of data and computational resources through a variety of interfaces similar in spirit to existing grid and HPC resource management and programming systems. These types of systems offer a new programming target for scalable

utilities, will provide the basic level of computing service that is considered essential to meet the everyday needs of the general community. To deliver this vision, a number of computing paradigms have been proposed, of which the latest one is known as Cloud computing. Hence, in this paper, we define

Our topics today in more detail What is cloud computing- old wine in new bottles? From the first idea to the BIG business. Why and when is Cloud Computing useful?

2. Cloud computing attacks

“Cloud ” computing – a relatively recent term, defines the paths ahead in computer science world. Being built on decades of research it utilizes all recent achievements in virtualization, distributed computing, utility computing, and networking. It implies a service oriented architecture through

Abstract — Cloud computing is an internet based network made up of large number of servers. Cloud contains the vast amount of information. And provide the variety of services to people.The benefit of Cloud computing are reducing the Data leakage,Decrease evidence acquisition time

How can cloud providers earn their customers ’ trust when a third party is processing sensitive data in a remote machine located in various countries? Emerging technologies can help address the challenges of trust in cloud computing. C loud computing provides many oppor-tunities for enterprises

. In step with technological changes, the paradigmatic pendulum has swung between increased centralization on one side and a focus on distributed computing that pushes IT power out to end users on the other. With the introduction of outsourcing and cloud computing, centralization in large data centers

thus bringing down the overall cost of IT infrastructure. In this paper, we present importance of Multi-tenancy in cloud computing, degree of Multi-tenancy and Multi-tenancy in databases. It will helpful to understand about Multi-tenancy and its benefits in software as a service in cloud computing
