Finally, ISVs gain on industry standard control over the entire software stack, from the operating system to hardware. the application, meaning they control the features, release schedule, and update schedule for all elements in the software stack. Overall, —Wikipedia a software appliance gives the ISV the benefits of traditional Software as a Service (SaaS), but in a format that is easier to build and maintain. For end customers, the integrated software appliance requires no complex integration of software components and no additional operating system or middleware expense—everything is built into the software appliance. Support and management costs are lower because the end customer has a single source for all issues and updates. In short, end customers get the simplicity of Software as a Service but with local control and data security that comes from deploying applications inside their firewall. .......................................................... rPath-WP-3 8/8/06 12:36 PM Page 2 ......................

Alikhanyan, Yerevan, Armenia 4 Lawrence Berkeley National Laboratory, 1 Cyclotron Road, CA 94720 Abstract. CernVM is a Virtual Software Appliance capable of running physics applications from the LHC experiments at CERN. It aims to provide a complete and portable environment for developing and running LHC data analysis on any end-user computer (laptop, desktop) as well as on the Grid, independently of Operating System platforms (Linux, Windows, MacOS). The experiment application software and its specific dependencies are built independently from CernVM and delivered to the appliance just in time by means of a CernVM File System (CVMFS) specifically designed for efficient software distribution. The procedures for building, installing and validating software releases remains under the control and responsibility of each user community. We provide a mechanism to publish pre-built and configured experiment software releases to a central distribution point from where it finds its way to the running CernVM instances via the hierarchy of proxy servers or content delivery networks. In this paper, we present current state of CernVM project and compare performance of CVMFS to performance of traditional network file system like AFS and discuss possible scenarios that could further improve its performance and scalability.
