Cédric Thomas, OW2 CEO, will give a presentation in the colocated event "Cloud Computing International Standardization Forum", on June 2 from 1:30 to 3:30. 

Title: OW2 and OCCI in the open cloud industry ecosystem

Abstract: This short lecture will highlight growing challenges faced by cloud computing users and how an emerging standard such as OCCI, can be part of the solution. Since the launch of Amazon EC2 in august 2006, cloud computing has boomed and been adopted as the dominant model for delivering Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as as Service and, more generally Everything as a Service (XaaS). Provisioning, managing and monitoring these outsourced, used-on-demand, paid-per-use and elastic resources require programmable interfaces for the cloud. A wide variety of different interfaces are available and this diversity energized the cloud computing market. However, behind the hype, cloud computing users are still confronted to major barriers: heterogeneity of cloud computing offerings, interoperability between cloud interfaces, integration to build multi-cloud systems and the portability of applications and cloud computing users activities. These issues have been addressed through libraries, brokering platforms and standards. We highlight the importance of Open Cloud Computing Interface (OCCI), a recommendation from Open Grid Forum (OGF). OCCI is a simple, open, extensible and self-described interface for managing every kind of resource as a service, not only IaaS. Although OCCI is supported by a large community it still lacks formal specification and associated engineering tools, fortunately an open source collaborative project such as OCCIware is addressing this limitation and everybody can join in.

    Details for Cédric Thomas presentation

    TITLE Open Source Software: the Governance Makes the Difference

    ABSTRACT: Many research and innovation projects adopt an open source approach from the implicit understanding that making the code of unfinished components freely available keeps open the opportunity for third-party stakeholders and contributors will finally complete the software. This is a possibility on the paper. But is not how open source actually works. This is not how open source communities grow nor how open source software becomes successful. In this presentation we hold that one of the key differences between a success open source project and a failed one is that the successful project implement flawless open source project governance.

    Title: *Interoperability on the cloud: myth or reality?*
    *Boris Devouge*, Microsoft - *Craig Sheridan*, Flexiant - *Jesse Proudman*, OpenStack Foundation
    Abstract: Customer moving applications, data and processes to the cloud might expect the same level of flexibility and control on the cloud than on their own conventional infrastructure. Interoperability between different cloud architectures – private, hybrid, public – and technologies is a way to meet customers expectations. Panelists will share their views on what comprises cloud interoperability, the maturity of technologies that enable it and recommended best practices.
