The document discusses OpenNebula, an open-source tool for managing virtual infrastructure in data centers. It addresses the challenges of portability and interoperability across cloud platforms. OpenNebula's approach leverages standards like OVF and CDMI and implements adaptors for interoperation. Examples are given of community projects collaborating with OpenNebula to develop standards-based solutions for cloud federation using OCCI.

9. Our Approach
Leveraging Existing Standards and Implementing Interoperation!
Standardization
● Implement standards
● Integrate with standards
Which Standard?
● Different de jure standards
● Several de facto standards
Interoperation
● Implement adaptors
● Use transformers
