From Grids to Clouds, a workshop for Grid users facing the Cloud (1/3)
(90 mins)
Avner Algom, Martin Antony Walker
SESSION 1: The Different Views of Cloud Computing
Cloud computing services, as offered by companies like Amazon, Google, IBM, Salesforce, Sun, and others, is on its way to become an important component of enterprise IT, adding a new, ‘external’ dimension of flexibility by enhancing one’s internal IT resource capacity when needed. The question still remains how useful the Cloud services model will be for the capacity and capability computing demands of the HPC community, in research and industry.
While grids and virtualization provide the ‘plumbing’ to enable seamless access to distributed resources, clouds denote services on a pay-per-use basis. Grids stand out because of their flexible, dynamic, feature-rich resources and thus are complex by their very nature. Cloud applications will likely follow similar strategies as grid-enabling ones. Just as challenging, though, are the cultural, mental, legal, and political aspects of clouds. Building trust and reputation among the users and the providers will certainly help in many simple scenarios.
This workshop will provide the Grid user community with solid information about the innovative potential and importance of Cloud technologies and services for research and business. This first session will start with the different views of Cloud computing and the differences, benefits, barriers, and their novelty with respect to the current state of Grid computing.
FYI: License management in Grids and Clouds will be covered in a separate BoF.

AIM of this Session: Presentation of positions by experts to share and discuss the different views of cloud computing and their novelty with respect to the current state of Grid computing. Presentations will focus on providing a clear definition of cloud computing, its real difference with Grid Computing and barriers for adoption. This session will try to give an answer to the following questions:
· What's the real difference between grid and cloud and why
could this be important to me ?
· Now that I have (invested in) a grid, why should I and
how can I transform (part of) this into a cloud ?
· Now that I (almost) understand the barriers to grid
computing, where are the barriers of cloud computing and
how can they be overcome ?
Agenda:
· Martin Antony Walker: Introduction
· Avner Algom: Cloud Computing - Pay-per-use for on-demand scalability, why now? Challenges and opportunities.
· Cal Loomis (CNRS and EGEE NA4 coordinator) / Marc Elian Bégin (Sixsq): Authors of EGEE Report “Clouds and grids - evolution or revolution?�
· Shantenu Jha (Louisiana University): Application-level Interoperability between
Grids and Clouds
Location: Caravaggio
