OpenNebula v1.4 brings a new framework to easily develop Cloud interfaces
by Ignacio Martin Llorente 23 Jul '09

23 Jul '09

Hi, This email is to inform that we have just released a beta version of OpenNebula v1.4, which brings among other innovations a new OpenNebula Cloud API (OCA) to easily develop any Cloud interface or Cloud application. As example we have implemented a new EC2 Query-API service on top of OpenNebula that exposes a subset of the Amazon's Query API. The OCA framework is being used to develop the RESERVOIR Cloud interface and will be used to develop the OGF OCCI API (see http://www.opennebula.org/doku.php?id=documentation:rel1.4#cloud_interfaces) I have just updated the resources page in the group WIKI with links to the new interfaces. Please note that OpenNebula 1.4 Beta 1 is not suitable for production settings. Its sole purpose is gathering feedback and testing the new exciting features, such as VMware support, libvirt implementation on a distributed system, advance contextualization…The final stable version will be released in September 2009.

Re: [occi-wg] new draft of the documents available...
by Thijs Metsch 23 Jul '09

23 Jul '09

Hi, We will split this overall docbook-book into two documents (which will comply to the OGF template). First on will be the specification and the second one about use cases and requirements. They will hopefully be generated out of the docbook easily...then the documents go through the normal OGF editor process and then we have to be compatible to OGF's thoughts :-D I aware of this topic and keeping track of it. We'll work on it before OGF 27. Cheers, -Thijs On Wed, 2009-07-22 at 10:12 -0600, Gary Mazz wrote: > I have a question about the format of the document.

Hi guys, Just a short reminder of our weekly concall. Same place same time: all the information can be found here: http://forge.ogf.org/sf/wiki/do/viewPage/projects.occi-wg/wiki/Teleconferen… Our Agenda for today includes: 1. Discussion about Cloud models 2. Draft API status 3. Misc. Feel free to add more in our wiki: http://forge.ogf.org/sf/wiki/do/viewPage/projects.occi-wg/wiki/Concall20090… Prior to joining our concall have a look at: http://sites.google.com/site/cloudarchitecture/ This is another point of view on how-to categorize Clouds. Have a look as the 'IaaS' box for example. Today we'll have a guest on the call with whom we can discuss this model and the differences to our ideas/thoughts.

Press coverage & presentations
by Thijs Metsch 22 Jul '09

22 Jul '09

Hi, Some of you already gave some presentations with a relationship to OCCI. I would like to ask to upload the slides here: http://forge.ogf.org/sf/docman/do/downloadDocument/projects.occi-wg/docman.… And documented your presentation here: http://forge.ogf.org/sf/wiki/do/viewPage/projects.occi-wg/wiki/Presentations Next to that we had some appearances in the press. There is a Wiki page covering all Press related stuff. If you see something with a relationship to OCCI - feel free to add it: http://forge.ogf.org/sf/wiki/do/viewPage/projects.occi-wg/wiki/Press I personally think it is very important to present to others what we are doing and where we are present. So please update those pages regularly. Thanks for helping out & talk to you later, -Thijs -- Thijs Metsch Tel: +49 (0)941 3075-122 (x60122) http://blogs.sun.com/intheclouds Software Engineer Grid Computing Sun Microsystems GmbH Dr.-Leo-Ritter-Str. 7 mailto:thijs.metsch@sun.com D-93049 Regensburg http://www.sun.com

Current work on documentation
by Thijs Metsch 20 Jul '09

20 Jul '09

Hi guys, I just wanted to give a short update on process of documentation. These are the things we are currently working on. We have two documents which will be released by OGF27. Those document will be called: - Open Cloud Computing Interface Specification - Open Cloud Computing Interface - Usecases and requirements for a Cloud interface The first document is the writeup of the OCCI API while the second documents sums up the requirements and use cases we have. The first document will be structured like this - so this is how we present OCCI: * Introduction * OCCI Walkthrough * Overview * Getting started * Operations * Collections * OCCI core specification * Basics * Extensions * Examples * Infrastructure * Nouns * Compute * Storage * Network * OCCI Registries It is important that we get this right - so to say that we can give this document to a implementor and he can implement it easily while just reading this document! Andy, Andre, Sam and me are working on this documents right now - but feel free to join or comment to us and the mailing-list. If you want to look at the current working copy of the document the sources can be found in the gridforge: http://forge.ogf.org/sf/scm/do/viewRepositorySource/projects.occi-wg/scm.Op… We are writing this up using docbook. The main article is called occi-book.xml which includes all the further articles. With the help of the Makefile you can create html and pdf versions of all the content. Sam and Andy will also send an update on the changes made to the version of in Wiki!

Comparison of Amazon, GoGrid, Sun, and RackSpace Cloud APIs
by shlomo.swidler＠gmail.com 17 Jul '09

17 Jul '09

William Vambenepe of Oracle published this comparison of the above four Cloud Infrastructure APIs today: http://stage.vambenepe.com/archives/863 He mostly focuses on how RESTful each one is, but I think his conclusions will not surprise this WG: Wouldn’t it be nice to just use a Web browser to navigate HTML pages > representing the different Cloud resources? Could I use these resource > representations to create mashups tying together current configuration, > metrics history and events from wherever they reside? In other words, could > I throw away my IT management console because all the pages it laboriously > generates today would exist already in the ether, served by the controllers > of the resources. Or rather as a mashup of what is served by these > controllers. Such that my IT management console is really “in the cloud”, > meaning not just running in somebody else’s datacenter but rather assembled > on the fly from scattered pieces of information that live close to the > resources managed. And wouldn’t this be especially convenient if/when I use > a “federated” cloud, one that spans my own datacenter and/or multiple Cloud > providers? The scalability of REST could then become more relevant, but more > importantly its mashup-friendliness and location transparency would be > essential. > > This, to me, is the intriguing aspect of using REST for IT/Cloud > management. This is where the Sun Cloud API would beat the EC2 API. Tim says > that in the Sun Cloud “the router is just a big case statement over > URI-matching regexps”. Tomorrow this router could turn into five different > routers deployed in different locations and it wouldn’t change anything for > the API user. Because they’d still just follow URLs. Unlike all the others > APIs listed above, for which you know the instance ID but you need to > somehow know which controller to talk to about this instance. Today it > doesn’t matter because there is one controller per Cloud and you use one > Cloud at a time. Tomorrow? As Tim says, “the API doesn’t constrain the > design of the URI space at all” and this, to me, is the most compelling > long-term reason to use REST. But it only applies if you use it properly, > rather than just calling your whatever-over-HTTP interface RESTful. And it > won’t differentiate you in the short term. Can anyone here solicit his feedback on our API? .. Shlomo
