| Abstract | Multiple Internet applications are often hosted in one datacenter and share underlying virtualized server resources. It is important but challenging to provide differentiated treatment to co-hosted applications and improve overall performance with efficient use of limited resources. We propose a coordinated self-adaptive resource management and admission control for multi-tier Internet service differentiation and performance improvement in a shared virtualized platform. We develop reinforcement learning based approaches for virtual machine (VM) auto-configuration and session based admission control. VM auto-configuration simultaneously provisions proportional service differentiation between co-located applications and improves application response time. Admission control improves session throughput of the applications, minimizing resource wastage due to aborted sessions. A shared reward actualizes coordination between the two learning modules. For system agility and scalability, we integrate reinforcement learning with cascade neural networks. We implement the integrated approach in a virtualized blade server system hosting multi-tier RUBiS applications. Experimental results demonstrate that the approach accurately meets differentiation targets and achieves performance improvement of applications. Our approach reacts to dynamic bursty workloads in agile and scalable manner. |

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.
