3. Open Cloud
Open Cloud = Open Standards + Open Source
 Open Standards
 Open Virtualization Format (OVF)
 Distributed Management Task Force (DMTF)
 Cloud Data Management Interface (CDMI)
 Storage Networking Industry Association (SNIA)
 Open Cloud Computing Interface (OCCI)
 Open Grid Forum (OGF)
 Open Source
 Open standards adoption
 Open innovation
 Open ecosystems
Because interoperability is not negotiable

4. It's all about Freedom
 Freedom to choose your cloud providers
 Freedom to publish your services on both public
andprivate clouds
 Freedom to use any type of hardware or software
 Freedom to move your applications where you
need, when you want
 Freedom to adapt the code to your own particular
needs
 Freedom to maintain control over the security and
the quality of the services

5. It's also about trust
 Trustworthiness is at the heart of cloud computing
 Openness and transparency to be guaranteed
 Open Source as a catalyst
 For cloud industry, standardization bodies and open
sourcedevelopers to work together
 to provide an efficient innovation model
 to solve trustworthy issues such as Interoperability, Audit, Safety,
Security, Privacy
 based on openness and collaboration
 Open Cloud as a lever
 to optimize chances for Europe to benefit from cloud computing
 to establish fair and fruitful dialogue with the US
