| Abstract | In a Cloud system, a number of services are often deployed with each service being hosted by a collection of Virtual Machines (VM). The services may interact with each other and the interaction patterns may be dynamic, varying according to the system information at runtime. These impose a challenge in determining the amount of resources required to deliver a desired level of QoS for each service. In this paper, we present a method to determine the sufficient number of VMs for the interacting Cloud services. The proposed method borrows the ideas from the Leontief Open Production Model in economy. Further, this paper develops a communication-aware strategy to place the VMs to Physical Machines (PM), aiming to minimize the communication costs incurred by the service interactions. The developed communication-aware placement strategy is formalized in a way that it does not need to the specific communication pattern between individual VMs. A genetic algorithm is developed to find a VM-to-PM placement with low communication costs. Simulation experiments have been conducted to evaluate the performance of the developed communication-aware placement framework. The results show that compared with the placement framework aiming to use the minimal number of PMs to host VMs, the proposed communication-aware framework is able to reduce the communication cost significantly with only a very little increase in the PM usage. |

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.
