| Abstract | Infrastructure as a Service (IaaS) providers typically offer multiple service classes to deal with the wide variety of users adopting this cloud computing model. In this scenario, IaaS providers need to perform efficient admission control and capacity planning in order to minimize infrastructure costs, while fulfilling the different Service Level Objectives (SLOs) defined for all service classes offered. However, most of the previous work on this field consider a single resource dimension -- typically CPU -- when making such management decisions. We show that this approach will either increase infrastructure costs due to over-provisioning, or violate SLOs due to lack of capacity for the resource dimensions being ignored. To fill this gap, we propose admission control and capacity planning methods that consider multiple service classes and multiple resource dimensions. Our results show that our admission control method can guarantee a high availability SLO fulfillment in scenarios where both CPU and memory can become the bottleneck resource. Moreover, we show that our capacity planning method can find the minimum capacity required for both CPU and memory to meet SLOs with good accuracy. We also analyze how the load variation on one resource dimension can affect another, highlighting the need to manage resources for multiple dimensions simultaneously. |

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.
