Open Architecture and Interfaces for Cloud Computing Interoperability

An architectural description of OpenNebula APIs

OpenNebula has been designed to be easily adapted to any infrastructure and easily extended with new components.  The result is a modular system that can implement a variety of Cloud architectures and can interface with multiple datacenter services. In the new white paper OpenNebula APIsC12G reviews the main interfaces of OpenNebula, their use and gives pointers to additional documentation for each one. Interfaces are classified in two categories: end-user cloud and system interfaces. Cloud interfaces are primary used to develop tools targeted to the end-user, and they provide a high level abstraction of the functionality provided by the Cloud. On the other hand, the system interfaces expose the full functionality of OpenNebula and are mainly used to adapt and tune the behavior of OpenNebula to the target infrastructure.
