rOCCI is an OCCI 1.1 compliant server implementation written in Ruby. Through its modular architecture it can be easily extended to support arbitrary Cloud Frameworks.
rOCCI as mentioned in our last blog post, is the OCCI implementation that powers the work which enables OCCI interoperability with Amazon EC2.
Work on rOCCI started as part of the EU FP7 project SLA@SOI under the working name OGF-OCCI in early 2011. The goal was to develop an OCCI 1.1 compliant server which initially supports OpenNebula and can later be easily extended to support other Cloud Frameworks. As OpenNebula offered a robust Ruby API binding, it was decided to develop the project in Ruby as well. Soon after work on the implementation started it was accepted as an official OpenNebula Ecosystem project.
Interoperability with other implementations of the OCCI standard was ensured by taking part in testing sessions during the SNIA Cloud Plugfests and using OCCI compliance tools such as the OCCI ANTLR Grammar and the DoYouSpeakOCCI tool. For the last Plugfest taking place at the end of February 2012, the project was renamed to rOCCI in order to distinguish it from the name of the standard (OGF-OCCI).
The current architecture of rOCCI is shown in the following overview:
