The ICCLab presented on the latest developments (PDF) in the Open Cloud Computing Interface at the Future Internet Assembly in Dublin. The session was organised by Cloud4SOA and the main theme was MultiCloud. In this regard, OCCI figures in many projects striving from this including EGI FedCloud, CompatibleOne and BonFire. In the presentation some future points of work that will be carried out in Mobile Cloud Networking, which took the audience’s interest.

OCCI was presented to the Cloud Application Management for Platforms (CAMP) group today. CAMP is a standard coming out of the OASIS group to define an interface to Platform as a Service offerings.

Here’s the presentation given.

At the EGI Technical Forum in Prague, the FedCloud task force presented their progress on bringing various standards together in order to compose a federated cloud within Europe. The presentation ended with an impressive live demonstration of that very work.

During the presentation eight different sites participated offering a set of standardised interfaces. Upon those sites cloud resources were allocated on very different infrastructure management frameworks but unified through the OCCI API. In one part of the demonstration 5 virtual machines were provisioned simultaneously, using OCCI, in Cyprus, Germany (2), Sweden and the Czech Republic. This was followed by a similar demonstration of provisioning storage and accessing that storage using CDMI through the same cloud resource providers.

In the European Grid Initiative Inspired Newsletter for September the recent activities of the EGI FedCloud initiative are summarised. OCCI is playing a key role for the goal of the Task Force to deliver a blueprint defining how federated virtualised environments can be implemented. A workable test bed has been set up by members of EGI as the implementation and deployment of a blueprint for cloud interoperability. Other standards at play also include OVF and CDMI.

The results of the EGI FedCloud inititative will be presented during the EGI Technical Forum taking place from 17.9.-21.9.2012 in Prague.

CompatibleOne provides an implementation of the OCCI server in C. You can also see all the OCCI-based services and interfaces that CompatibleOne supports. CompatibleOne has a clear focus on the need of interoperability in the Cloud and so uses OCCI.

The Storage Networking Industry Association’s Cloud Storage Initiative (SNIA CSI) and the Open Grid Forum (OGF) are conducting the second in a series of international cloud plugfests slated for 2012.

What?

Cloud Plugfest sponsored by SNIA CSI/OGF

When?

June 14 – June 17, 2012 Where: Shenzhen, CN (Asia) Amsterdam, NL (Europe) Chicago, Illinois (North America)

Who’s invited?

All cloud implementers are invited to participate either in person or remotely. Participants need not be members of the SNIA, CSI or OGF and the cost to attend is FREE!*

Why attend?

The cloud plugfest will offer a highly collaborative, vendor-neutral, environment for developers and vendors to perform interoperability testing of CDMI and OCCI implementations. By attending the cloud plugfest participants will:

• Gain a greater understanding of what the needs are for establishing better interoperability with Cloud Computing and Cloud Storage standards, and the opportunity to refine those standards.
• Gain a better understanding of the requirements for interoperability integration between Cloud Storage (CDMI) and Cloud Computing (OCCI)
• Interact directly with cloud implementers and early adopters of CDMI and OCCI

How to register?

The cost to register is free. Visit the cloud plugfest page for additional details.

* Plugfest registration is free. Attendees are responsible for all other costs (travel, meals, etc.) associated with participating in this event including any participation fees imposed by co-located venues or event sponsors. For questions or comments about the SNIA Cloud Storage Initiative or this plugfest, please contact Tom Mancuso at csimanager – at – snia.org.

A team in Engineering (partially funded by Venus-C) have released a tool, ovf4one, which provides an OCCI interface that accepts OVF and provisions resources through the OpenNebula OCA interface. It is implemented in Java and implements the OCCI specifications and uses OVF messages and OpenNebula as backend.

From a technical perspective, ovf4one is an OCCI to OCA gateway, translating RESTful OCCI calls into OCA RESTful calls and the OVF XML message is translated into OpenNebula VM templates. This project has been realised as part of Venus-C EU project.

We blogged previously about the availability of an OCCI implementation for OpenStack. Below is a screen cast that demonstrates some, not all, of the functionality available.

Hot on the heels of the OCCI OpenStack implementation (wiki, code review) a number of our community members (big thanks to Eugene from R2AD) will be organising an OpenStack Design Summit unconference OCCI session. All are welcome to it from the inquisitive to the sceptical!

Topics to be discussed include:

• What is OCCI and its goals?
• Where does OCCI fit the OpenStack picture?
• How should OpenStack address “extra” APIs?
• Q&As

The session will be on Wednesday at 4.30pm.in the Golden Gate room.

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:

Current features include:

• Full OCCI 1.1 support
• Experimental support for EC2 (current development version)
• Easy deployment in an Nginx or Apache webserver by using Phusion Passenger
• Usage of the official OCCI ANTLR grammer for parsing / validation
• Passing the DoYouSpeakOCCI Compliance Testing Facility
• Support for the current draft of the OCCI JSON rendering specification
• Modular, easy to extend backend management
• Support for OpenNebula 3.0 and 3.2
• Dummy backend for testing
• Support for HTTP basic authentication
• Experimental support for X.509 certificate authentication (current development version)
