The document discusses OpenNebula, an open-source tool for managing virtual infrastructure in cloud computing. It describes OpenNebula's interoperability and portability features, challenges in these areas, and the community's approach of leveraging standards. Examples are given of collaborations using standards like OCCI and OVF to enable interoperability between OpenNebula and other cloud platforms.

8. Who Use OpenNebula?
Different Models of Deployment!
Model Definition Cloud Cases
Infrastructure is owned by • Optimize and simplify internal operation
Private
a single organization and • SaaS/PaaS support
made available only to the • IT consolidation within large organizations
organization (Goverment Clouds, University Clouds…)
Infrastructure is owned by • Commercial cloud providers, mostly
a single organization and hosting providers to offer low cost solutions
Public
made available to other with limited control/configuration and
organizations over the security/reliability good enough
Internet • Science public clouds to enable scientific
and educational projects or to experiment
with cloud computing
Infrastructure is owned by • Telecom cloud providers to offer premium
Private
Virtual
a single organization and solutions with additional control/
made available to other configuration and security/reliability
organization over a
dedicated private network

10. 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
