Cloud computing is a unique technique for outsourcing and aggregating computational hardware needs. By abstracting the underlying machines Cloud computing is able to share resources among multiple mutually distrusting clients. While there are numerous practical benefits to this system, this kind of resource sharing enables new forms of information leakage such as hardware sidechannels. The usag...

Cloud computing has taken place to be focused by educational and business communities. These concerns include their needs to improve the Quality of Services (QoS) provided, also services such as reliability, performance and reducing costs. Cloud computing provides many benefits in terms of low cost and accessibility of data. Ensuring these benefits is considered to be the major factor in the cl...

Cloud environment is very different from traditional computing environment and therefore tracking the performance of cloud leverages additional requirements. The movement of data in cloud is very fast. Hence, it requires that resources and infrastructure available at disposal must be equally competent. Infrastructure level performance in cloud involves the performance of servers, network and st...

Cloud Computing is an emerging style of IT delivery in which applications, data and IT resources are rapidly provisioned and provided as standardized offerings to users called consumers over the web in a flexible pricing model. Cloud provider is responsible for providing quality of services to cloud consumers. A cloud typically contains a significant pool of resources, which could be reallocate...

Cloud computing is the next generation computing. Adopting the cloud computing is like signing up new form of a website. The GUI which controls the cloud computing make is directly control the hardware resource and your application. The difficulty part in cloud computing is to deploy in real environment. Its’ difficult to know the exact cost and it’s requirement until and unless we buy the serv...

Cloud computing changed recently business view regarding their Information System through an on-demand provisioning of computing resources. Recent discussions about data security requirements in cloud computing environment tend to conflict with other requirement including usability and economic. In hybrid clouds that combine private and public clouds usage, private clouds are able both to exter...

Simulations over Cloud environments introduce additional benefits from Cloud Computing to conventional distributed simulations, including elasticity on computation resource, cost saving on investment, and convenience of service accessibility. There exist some works that attempt to apply Cloud computing on distributed simulation. However, there is one significant drawback on those works: lack of...

Cloud computing has emerged as the most dominant computational paradigm in recent times. There are tremendous benefits for enterprises adopting cloud technologies. It provides resources and services on demand, pay-as-you go basis. This includes infrastructure, platform and software services. But there are still a number of security threats and challenges associated with utilizing cloud computin...

The concept of cloud computing was introduced to meet the increase in demand for new application for a project, and to provide a large storage facility whenever or wherever a user needs it. The cloud system facility helped many industries as well as individual users to get authentic software at a very low cost. But with this new system comes the major concern of security, as the connection to t...

Cloud computing Environment provides the platform to share computing resources and provide different services like SaaS, PaaS and IaaS that will used by organization as private, public or Hybrid. Cloud computing basically known as Everythingas-a-service .Since cloud computing is used shared distributed resources over the world wide network (e.g., internet) in the open environment, thus it will ...
