Abstract

In this article, the author collects some definitions and concepts related to green computing model for clouds. Greening your computing equipment is a low-risk way for your business to not only help the environment, but also to reduce costs. Reducing energy usage, which also reduces carbon-dioxide emissions and your energy bill, is the most effective thing you can do. Green computing can be defined as the efficient use of computing resources. Computing reduced power consumption is environmentally less expensive. It is also associated with the proper use of computing resources and plays a vital role in minimizing their dangerous impact on surroundings. The strength of public and community opinion shifting in favour of environmental responsibility is also growing rapidly. Computing is also an area of human activity in which there are real environmental savings to be made, some of which can be achieved by implementing relatively straightforward practical measures with existing hardware.

Abstract

Cloud computing is an on demand service as it offers dynamic, flexible and efficient resource allocation for reliable and guaranteed services in ‘pay-as-you-use’ manner to the customers. Such a process of allocation and de-allocation of resources is the key to accommodate unpredictable demands. However, despite the recent growth of the Cloud Computing market, several problems with the process of resource allocation remain unaddressed. A system that uses virtualization technology and skewness algorithm to allocate data center resources dynamically based on application demands and support green computing by optimizing the number of servers in use had been presented. The result reveals the achievement of both overload avoidance and green computing for systems with multi resource constraints.

Abstract

The two layer encryption is to enforce the fine-grained access control on confidential data hosted in the cloud, based on fine-grained encryption data. Under this scenario, data owners are encrypting the data before uploading them on the cloud and re-encrypting the data whenever users change to an alternate. Here the owner is communicating with clouds and users. The better approach used is to minimize the overhead work at the data owners. So, the authors have proposed an approach by using multi layer encryption, whereas the cloud performs a fine-grained encryption. A challenging issue is how to decompose Access Control Policies (ACPs) such that the multi layer encryption can be performed. In the present context, the authors have used novel optimization algorithm and KeyGen algorithm. Also, an efficient group key management scheme, that supports ACPs to work efficiently, is also used.

Abstract

Disease diagnosis is a major issue in healthcare system; day to day new diseases are being found with different symptoms. So, identifying the disease is a big challenge for common people .The rapid development of cloud computing and android technology makes healthcare system work simple. By using these technologies, we have developed this mobile cloud based approach for disease diagnosis system. Here, the authors have proposed a mobile cloud based architecture for enabling disease diagnosis. We developed an android application for the users; it is a very user friendly application to use without any prior knowledge and the cloud server will have the details of the diseases, precautions, hospital and medical volunteers that respond to the user request. This application can predict the disease based on the given symptoms’ combination using decision trees from the training data. The main aim of this research is to predict the disease name based on the patient’s selected symptoms and provide necessary remedies and hospital details. If any extra information is needed, it suggests the medical voluntaries.

Abstract

Cloud computing refers to the web-based computing services that allows the users to access hardware and software applications operated and governed by an institution or organization in far-off areas. Cloud computing necessities the storing of data, user applications and sharing of information and computer resources. This technology is considered as boon, especially to the educational institutions as these institutions can streamline their administrative functions, mend the communication process among their staff members, afford global partnership and also reduce the IT infrastructure cost. Various scholarly articles are available regarding the adoption and benefits of cloud computing in educational institutions the major focus being laid on the deployment models, service providers, the educational platforms and also the efficiency of cloud computing in e-learning process. Some studies also give an insight about the implementation of these services in Indian Universities. However, there are very few studies which discuss the barriers in implementing cloud computing in educational institutions and hence the scope for further empirical study is needed in this perspective. This paper critically reviews the key benefits of deploying cloud computing in education and the major challenges in implementation and the possible measures to overcome the identified barriers.
