Scientific applications are developed to run in specific computing environments and use several infrastructures that provide low-level resources, such as storage, networks, and fundamental computing resources, to the users who do not have knowledge of their exact location and hardware specifics.A framework is needed to scale-up or scale-out applications dynamically on provisioned resources.WNoDeS is a cloud and grid virtualization framework that introduces cloud-based services and supports virtual machines for local and grid users alike.This paper presents the access to scientific applications of different user communities, such as astro-particle physics with the Auger experiment, and life science with WeNMR virtual research community, through this framework.It details both use cases that had to be addressed for the described communities and further requirements that WNoDeS is able to achieve.The paper also shows how direct instantiation of virtual machines can be fulfilled by using both an OCCI-compliant CLI and a Web portal.
