Title: Exploiting Virtualization and Cloud Computing in ATLAS

The ATLAS Computing Model was designed around the concepts of grid computing; since the start of data-taking, this model has proven very successful in the federated operation of more than one hundred Worldwide LHC Computing Grid (WLCG) sites for offline data distribution, storage, processing and analysis. However, new paradigms in computing, namely virtualization and cloud computing, present improved strategies for managing and provisioning IT resources that could allow ATLAS to more flexibly adapt and scale its storage and processing workloads on varied underlying resources. In particular, ATLAS is developing a "grid-of-clouds" infrastructure in order to utilize WLCG sites that make resources available via a cloud API.

This talk will present the current status of the Virtualization and Cloud Computing R&D project in ATLAS Distributed Computing. This will include strategies for deploying PanDA queues on cloud sites, performance testing of various workloads on virtualized/cloud resources, and a discussion about future strategies for exploiting cloud-based storage.
