| Abstract | With the growth of the Cloud Computing paradigm, a new challenge appears in the development of data centers: energy efficient load balancing in a dynamic and scalable environment with an undefined number of heterogeneous resources. In this context, considering that idle servers consume up to 60% of peak energy and the fact that usually the level of usage for a server is 20-30%, new load balancing strategies are required. In this paper we present the various properties of a novel, biologically inspired, spider mesh overlay used for load balancing non-preemptive tasks, each task consuming a certain amount of resources. Each node of the overlay is capable of offering the best capacity for a certain resource (e.g. powerful CPU for CPU-bound tasks) while offering smaller capacities for the other resources. Various routing policies are used in order to assign a job to a fitting node or in the worst case, provision/switch-on another node. The jobs are distributed by a central broker using two methods: round-robin and a clustering approach. In order to test our methods we implemented a simulator for the datacenter and the spider mesh overlay, the simulated resources being sampled from a gaussian distribution. Experimental results are promissing as both the round-robin and clustering approach show an overall server load of more than 50% in the proposed worst case scenario. |

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.
