Abstract:
-Nowadays, the eScience big issue in Cloud Com- puting is how to leverage on-demand computing in scientific research. For this purpose, the specifics requirements of the complex scientific applications have been addressed with DIRAC, which has the motto the interware, because it is a proven scientific community solution, currently providing transparent access and interoperability between different distributed infras- tructures, such as European Grid Infrastructure (EGI), Open Science Grid (OSG), computing clusters, standalone hosts, and cloud infrastructures. In this context, Federated Hybrid Clouds are emerging as a model of coordinated service access and delivery to multiple Infrastructure as a Service (IaaS) providers. The term hybrid comes from the integration of community clouds and commercial clouds in a federated manner, which also requires the use of additional services, such as federated authentication, accounting or monitoring. This paper explains how DIRAC is providing Software as a Service (SaaS) for generic scientific computational purposes. The cloud extension of DIRAC (VMDIRAC) is used to instantiate, monitor and manage Virtual Machines (VMs) in multiple IaaS aggregations of Amazon EC2, OpenNebula, OpenStack and CloudStack. Furthermore, DIRAC and VMDIRAC extension can provide SaaS of any scientific application through a contextualization management of few golden VM images, which automates the necessary context to run transparently in multiple IaaS providers, as well as the required software and tools for any eScience application.
