CloudScape III - Taking <strong>European</strong> Cloud Infrastructure Forward OCCI - Open Cloud Computing Interface specification set General overview and field of application The Open Cloud Computing Interface from the Open Grid Forum is a RESTful protocol and API for cloud-related management tasks. OCCI can be used by any device or programming language that is able to understand HTTP, and provides for easy monitoring and testing through the HTTP Rendering. Originally initiated to create a remote management API for IaaS-based services, it has since evolved into a flexible API while still offering a high degree of extensibility. The current release is suitable to serve many other models in addition to IaaS, including e.g. PaaS and SaaS. The importance of interoperability The current OCCI specification set consists of three documents. Future releases are planned to include additional rendering and extension specifications. »» OCCI Core: Provides the formal definition of the OCCI Core Model. »» OCCI HTTP Rendering: Defines how to interact with the OCCI Core Model using the OCCI API, including how the Model can be communicated and serialized using the HTTP protocol. »» OCCI Infrastructure: Contains the definition of the OCCI Infrastructure extension for the IaaS domain; also defines associated resource types, their attributes and the actions that can be taken on each resource type. 56 Adoption by the open source community OCCI has achieved wide adoption in the open source community and has attracted considerable interest from the commercial community and from other standards organizations due to its built-in inter-compatibility with other RESTful methods. Implementations exist that can be downloaded and used from a number of projects, including the following: 1. Implementation of OCCI on top of libvirt by the Distributed Computing Virtual Laboratory at the Robotics Research Institute, Technische Universität Dortmund. 2. A BSD-licensed OCCI implementation on top of Apache Tashi by SLA@SOI. 3. An open source implementation of OGF OCCI for Eucalyptus under development by he UK-JISC funded project “Flexible Services for the Support of Research.” 4. Adoption of OCCI into the roadmap and project plan for OpenStack, scheduled for the upcoming ‘bexar’ release.
5. A reference implementation of the OCCI specification by the OpenNebula project, scheduled to be updated to the latest version in the near future. 6. An implementation of the OCCI protocol/API as part of the Service Sharing Facility (SSF) for the German Research Project DGSI, developed by Platform Computing. All of the above implementations except for OpenStack are already fully functional, and many have been in the form of working code for existing projects for some time. The latter implementation includes demos for Job Submission (SaaS/PaaS), a KeyValue store (PaaS) and an included skeleton implementation of the OCCI infrastructure model, which can be bound to any available hyper-visor to create an IaaS based cloud. The OCCI specifications are designed to allow boundary-level interfaces to be built using RESTful patterns over HTTP, and can thus be applied to almost any existing software infrastructure component or layer to provide a standards-based way to adapt it to the cloud. This feature accounts for their high degree of interest and adoption. Possible future cooperation Formal release of the OCCI specifications is expected by the end of 1st quarter 2011. The OCCI group welcomes notification regarding additional implementations and further work, and collaborates through its ogf.org working group pages supplemented by a dedicated web site at occi-wg.org that hosts links to downloadable examples of the implementations described above.
