| Abstract | Infrastructure-as-a-Service (IaaS) cloud platforms have brought two unprecedented changes to cluster provisioning practices. First, any (nonexpert) user can provision a cluster of any size on the cloud within minutes to run her data-processing jobs. The user can terminate the cluster once her jobs complete, and she needs to pay only for the resources used and duration of use. Second, cloud platforms enable users to bypass the traditional middleman---the system administrator---in the cluster-provisioning process. These changes give tremendous power to the user, but place a major burden on her shoulders. The user is now faced regularly with complex cluster sizing problems that involve finding the cluster size, the type of resources to use in the cluster from the large number of choices offered by current IaaS cloud platforms, and the job configurations that best meet the performance needs of her workload. In this paper, we introduce the Elastisizer, a system to which users can express cluster sizing problems as queries in a declarative fashion. The Elastisizer provides reliable answers to these queries using an automated technique that uses a mix of job profiling, estimation using black-box and white-box models, and simulation. We have prototyped the Elastisizer for the Hadoop MapReduce framework, and present a comprehensive evaluation that shows the benefits of the Elastisizer in common scenarios where cluster sizing problems arise. |

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.
