The document discusses CompatibleOne, an open source "cloudware" that allows creation, deployment, and management of private, public, and hybrid cloud platforms. It promotes open standards like OVF, CDMI, and OCCI to achieve interoperability between clouds and freedom for users. CompatibleOne uses ACCORDS and CORDS to provide a common description schema and enable provisioning of resources across different cloud carriers through standards-based interfaces.

Interoperability
Matters

2. ECOSYSTEM

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 and
private 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
