A platform to deploy customized scientific virtual infrastructures on the cloud

摘要

This paper presents a software platform to dynamically deploy complex scientific virtual computingrninfrastructures, on top of Infrastructure as a Service Clouds. The platform orchestrates different servicesrnto provision the virtual computing resources. It dynamically installs the appropriate software to satisfyrnthe requirements of a researcher, both on public and on-premise Clouds. The platform provides a webrninterface to enable the users to easily manage the life cycle of virtual infrastructures. It enables users torndefine infrastructures, share them with other users, deploy and relinquish them, add or remove resourcesrndynamically, create and share application recipes, and so on. The paper also describes three case studiesrnto deploy complex infrastructures, namely, a Hadoop cluster, a single-node to perform Next GenerationrnSequencing and a gateway for users to access the European Grid Infrastructure. This platform promotesrna better use of on-premise hardware resources of a research center by allocating the computing resourcesrnjust-in-time to the specific life time of the virtual infrastructures as well as the deployment of the very samerninfrastructures on a public Cloud.
