| Abstract | Enterprise data centers increasingly adopt a cloud-like architecture that enables the execution of multiple workloads on a shared pool of resources, reduces the data center footprint and drives down the costs. A number of cluster resource managers have appeared over the last few years, aimed at providing a uniform technology-neutral resource representation and management substrate. Examples include Apache YARN, Google Borg and Omega, Apache Mesos, and IBM Platform EGO. The Apache Mesos project [2] is emerging as a leading open source resource management technology for server clusters. Mesos offers simple yet powerful and flexible APIs, highly available and fault tolerant architecture, scalability to large clusters, isolation between tasks using Linux containers, multi-dimensional resource scheduling, ability to allocate shares of the cluster to roles representing users or user groups, and a clear separation of concerns between the applications (termed frameworks) and the "cluster kernel", which is Mesos. The resource scheduler of Mesos supports a generalization of max-min fairness, termed Dominant Resource Fairness (DRF) [1] scheduling discipline, which allows to harmonize execution of heterogeneous workloads (in terms of resource demand) by maximizing the share of any resource allocated to a specific framework. However, the default Mesos allocation mechanism lacks a number of policy and tenancy capabilities, important in enterprise deployments. We have investigated integration of Mesos with the IBM EGO (enterprise grid orchestrator) technology [3] which underpins various high performance computing, analytics and big data clusters in a variety of industry verticals including financial services, life sciences, manufacturing and electronics. We have designed and implemented an experimental integration prototype, and have tested it with SparkBench workloads. We demonstrate how Mesos can be enriched with new resource policy capabilities, required for managing enterprise data centers, such as • Capturing of the hierarchical structure of an enterprise (organisations, departments, groups, teams, users) by defining the corresponding resource consumer tree; • A fine grained resource plan allowing to define resource share ratio, ownership and lending/borrowing policies for each resource consumer; • A rich set of resource management policies making use of the hierarchical resource consumer model and providing fairness and isolation to the members of hierarchy including an important ability to dynamically change the allocations (time-based policy); • A Web-based GUI providing a centralized console through which the whole cluster is observed and managed. In particular, the cluster-wide resource management policies are applied through this GUI. |

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.
