Gartner’s Recommendation: Use 3rd-party Cloud APIs…

Posted September 30th, 2012 in News by admin

An interesting article (by @cloudpundit) from Gartner: Don’t Let OpenStack Hype Distort Your Selection of a Cloud Management Platform in 2012. The recommendations are not specific for OpenStack. The following table form the exact same article gives a nice impression of Garnter’s recommendations:

(Source: http://imagesrv.gartner.com/reprints/238300/238322/238322_1.gif)

The second recommendation is probably most interesting: ‘Use a 3rd party cloud API library [...]‘ – Why not even go for an Open Community Standard Driven Cloud API? OCCI for OpenStack is the answer and an implementation deployed on the EGI FedCloud.

Upcoming CloudPlugfest

Posted May 29th, 2012 in News by admin

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.

OCCI and OVF

Posted May 3rd, 2012 in News by admin

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.

OCCI OpenStack Demo

Posted April 17th, 2012 in News by admin

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.

OCCI at the OpenStack Design Summit

Posted April 14th, 2012 in News by admin

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 – A Ruby OCCI Framework

Posted April 2nd, 2012 in News by FlorianFeldhaus

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:

rOCCI is currently mainly developed by employees of GWDG. New contributors are very welcome. For more information visit:

OCCI’fied Amazon EC2

Posted March 21st, 2012 in News by admin

OCCI has been successfully mapped and implemented upon the Amazon EC2 API. The work has been carried out by TU Dortmund University in cooperation with the compute and research center GWDG. The implementation uses the rOCCI framework – more on that in a later post!

German Government Recognises OCCI as Leading the Cloud Standards Arena

Posted March 18th, 2012 in News by admin

Today, we are happy and proud to find the German Federal Minstry of Economics and Technology (BMWi) fully endorses OCCI in its freshly published analysis on “The Standardisation Environment for Cloud Computing”.

This is a big vote of confidence in our work which was echoed by the UK G-Cloud report. Being picked up by the German government is obviously kudos to the community’s work, especially as it shows OCCI as a leader of current Cloud standardisation activities.

Lately, OCCI has received a lot of attention: the leading open-source cloud computing software stack implements it, a commercially focused project and related companies builds its whole ecosystem around it, the largest eInfrastructure provider in Europe endorses it, and many other things are ongoing around it.

The study identifies 19 standardisation organisations as “leading”, among which well-known international ones such as ISO, NIST, SNIA, and DMTF are listed next to OGF, the home of OCCI, and other European ones, such as ETSI and BITKOM.

Regarding standards, the report features “20 prototypical cloud standards [that] serve as models, […] and are greatly respected by experts”. Looking at this in detail, it is hugely encouraging to see that OCCI is considered to be the one with the greatest importance (together with OpenStack, which is on the way of speaking OCCI as well, and OAuth, which is orthogonal): the matrix above shows the classification by Booz and Partners on behalf of the BMWi. If you take a look on the upper right, you’ll find that OCCI is not only the one with the greatest maturity and quality, but also has the highest dissemination potential!

The report makes an analysis from the European and German point of view, and discusses the current field of standardisation in the Cloud arena. Stating that “the standardisation environment for cloud computing is only just starting to develop”, the report identifies OCCI (next to OVF, OpenStack, and CDMI) as “proving attractive”. It features a taxonomy of standards in cloud computing along challenges they address (“why?”) and the basis of their approach (“how?”), and identifies nine challenges, with data privacy the most prevalent, next to three fields (technology, management, and legal).

Well done to all and thanks to Alexander for the article and translations!

Do You Speak OCCI?

Posted March 5th, 2012 in News by admin

The doyouspeakOCCI Compliance Testing Facility is a Google App Engine (GAE)-based checking tool for the Open Cloud Computing Interface (OCCI) family of specifications. More specifically, it provides a full compliance test suite for the OCCI Core (GFD.183)OCCI Infrastructure (GFD.184), and OCCI RESTful HTTP Rendering (GFD.185)specifications.

doyouspeakOCCI is written in Python and heavily building on the GAE services, mainly Task QueueURL Fetch, and the webapp Framework.

Note that doyouspeakOCCI is not to be considered the “official” testing suite for OCCI endorsed by the Open Grid Forum, but rather than that, a third-party contribution which aims to be as close as possible. For a more thorough explanation, please take a look at the wiki pages.

How to Use

doyouspeakOCCI was hard to implement, but is simple to use. Just point your browser tohttp://doyouspeakocci.appspot.com, enter the base URL of your OCCI implementation, and press “Go!”.

Optionally, you can provide credentials for HTTP basic auth, if your service is secured. We strongly recommend to use a one-time test account; although we promise to use the credentials only for the compliance test, we cannot guarantee what others on the way (especially GAE) will do with them. In the near future, doyouspeakOCCI will support OAuth to ameliorate this issue.

Please note that doyouspeakOCCI records data on every test run in the GAE DataStore. This is done solely for the sake of displaying usage statistics. Within the limitations of applicable jurisdiction and the GAE Terms of Service, we will not disclose this data to anyone beyond what is being displayed on the doyouspeakOCCI web presence.

For other questions, please also take a look at the FAQ.

Where to Get

doyouspeakOCCI is available as a source code release only, which can be obtained by two ways:

Alternatively, you might want to pick one of the advertised downloads (click on the “Downloads” button in the upper right of the doyouspeakOCCI development home page at GitHub.

If you wish to run the service on your local system for testing purposes, please take a look at the doyouspeakOCCI Installation Guide for a detailed explanation on how to setup the environment.

Contributing

doyouspeakOCCI aims to be a community effort, and help is always welcome. Please contact us on the mailing list to learn more.

OCCI and OpenStack

Posted March 1st, 2012 in News by admin

OpenStack is one of the major players in the cloud community at the moment. Still it currently lacks an standardized Interface which can be used to manage VMs. This changes now! During the Cloud Plugfest OCCI has been demoed on top of OpenStack.

The blueprint (details on wiki) for this feature enhancement has been around a while now. And based on this blueprint a first implementation has been created.

Andy Edmonds presented the following slides during the Cloud Plugfest in Düsseldorf which highlight more details of the OCCI interface for OpenStack

As noted this work has partly been sponsored by dgsi and FI-WARE. Now on to interoperability testing and looking into getting other Standards like CDMI on top of OpenStack.
