| Abstract | recently, big data computing in cloud systems is an important issue. Cloud computing tries to satisfy users' demands and provide services by sharing hardware and software resources. Therefore, using the virtualization technology to enhance system performance is an important goal. In practical, single cloud cannot provide unlimited services with limited physical resources. Therefore, this study proposes a vertical/horizontal resource scaling mechanism for federated clouds. When single virtual machine is unable to satisfy user requests, the proposed mechanism will allocate new resources in the federated clouds by vertical/horizontal scaling fashions. In general, horizontal scaling obtains more computing power by adding more virtual machines, and vertical scaling obtains more computing power by adding resources in the virtual machine. The vertical-scaling system not only enhances the system performance but also increases physics machine utilization. But the vertical- scaling system incurs the communication latency problem. Therefore, this study focuses on the vertical /horizontal scaling approach for reducing the minimum turnaround time and for improving the cost efficiency. Our study assessments the cloud computing capability by using cost efficiency (throughput/price per minute). Performance for NAS Parallel Benchmarks (for example, Parallel (EP), Conjugate Gradient (CG), Integer Sort (IS)) is evaluated. Experimental results show that our approach cloud reduce communication overhead and improve the resource utilization and throughput. Keywords - federated cloud, vertical scaling, horizontal scaling. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
