GaaS 2.0: the new release based on Openstack with features implemented with OCCI.

Cloud Computing has been widely adopted as an alternative paradigm respect to Grid Computing to provide resources because of the advantages it brings to both users and providers. GaaS was born with the aim to enable the use of Cloud-provided resources with well-established Grid-like interfaces, avoiding the need for users to learn new resources access and use models. In previous experiences we developed a prototype for GaaS, by using the most used Cloud open source technologies and frameworks available at that time (e.g. Eucaliptus, OpenNebula, ...). Here we present the final stage of our work on GaaS that now is based on several de-facto and consolidated standards in Cloud, Virtualization and Grid worlds: Openstack, KVM and EMI. Furthermore, we present both a) a production level version of GaaS and b) GApp the mobile interface to the GaaS framework.
