| Abstract | Data centers have been criticized for being heavy consumers of energy, accounting for a significant share of the world's total energy use. This is compounded by the fact that a large portion of the computational resources in data centers remains idle most of the time, while nevertheless consuming a great amount of energy even in an idle state. One of the causes of resource idleness is the static resource allocation strategy of the widespread quota management systems in private clouds, which commonly do not keep track of the utilization rate of allocated resources, which are often idle. Better resource management strategies are therefore called for to improve the utilization rate of available capabilities and thereby minimize operational costs. We propose here a method for resource provisioning based on utilization-rate forecasting for clouds with data-processing PaaS environments. A clustering algorithm is used for estimating and dynamically scheduling the workload of batch applications. Based on current and historical records of resource utilization, the algorithm enables taking efficient scheduling decisions. Due to the non-proportionality of computing power consumption, we show that compared to static quota management systems for private clouds, average increases of 10+ in CPU and RAM utilization and 20+ in the number of processed jobs may be obtained without a significant reduction in the quality of service. |

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.
