First day at the Open Grid Forum

May 27th, 2009 • Comments Off on First day at the Open Grid Forum

We are already in the second day of the OGF meeting. Nevertheless the first day has been interesting and full of information. This time not so many attendees are here in Chapel Hill. Which makes this meeting more a working meeting than a collaboration meeting like last OGF.

Still I got some great feedback about the work done in OCCI. And it somehow comes to my mind that it can be indeed a big thing to happen. I’ll be giving a presentation and introduction of OCCI tomorrow in our working group meeting. Other presenters will also show their works and thoughts on Clouds – so stay tuned! The slides will be available.

A great session yesterday was hosted by Craig Lee, himself President of OGF, about the strategic position of OGF. He talked a lot about OGF relation towards Clouds and that OGF has a great standpoint with OCCI. But there is a need for collaboration with other Standard efforts like those from SNIA and DMTF. Therefor OGF will trigger this and work on collaboration. Next to that a OGF representative will be available at the main Cloud summits and conference to present this view.

Next to that here are some impressions from OGF. Watch closely to the Jelly Beans I got here during coffee break 🙂

Nice slides about Clouds and Grids.

Open Cloud Computing Interface at the Open Grid Forum

Today is the first day of the Open Grid Forum meeting here in Chapel Hill, NC. And during the the opening session the President of the Open Grid Forum (OGF) Craig Lee and the VP of Standards Chris Smith both stated the OCCI working group meeting as a high-light.

Currently it looks like the OCCI will be the first group to have a implementational ready API! And with this background and the collaborations to other groups like DMTF, SNIA and other standardization bodies it looks like OCCI is becoming a great thing! And for me fun to work on 🙂

OCCI has currently a great momentum! And with over 130 subscribed persons on the mailing-list there is a lively and active discussion. Contributions come from individuals, large companies and end-users of the Cloud. Even some of the persons on the list have their own Wikipedia page.

Open Cloud Computing Interface at Open Grid Forum

May 22nd, 2009 • Comments Off on Open Cloud Computing Interface at Open Grid Forum

The Open Grid Forum meets next week in Chapel Hill, NC. And currently two session are scheduled for the Open Cloud Computing Interface working group OCCI (http://www.occi-wg.org):

Thursday, May 28 1:30 pm – 3:00 pm OCCI – Group session

Thursday, May 28 3:30pm – 5:00 pm OCCI – API discussion

There will be dial-in lines if possible.

So please join and collaborate on the OCCI efforts. If everything works out fine we will be presenting a first draft API in these sessions. One of the first Standards in Clouds without a vendor-locking!

Modularity in Software and Space

May 20th, 2009 • Comments Off on Modularity in Software and Space

I am a big fan of modular software. It allows the reuse of software parts and clear designs. Especially the later one. Think of a Object Orientated Software project where 100 of classes can just call each other – We invented OO programming for more cleaner designs and now the dependency graphs look horrible (have a look here), because every class depends on other classes and no clear boundaries are available.  With the help of modular design it is possible to clean it up. But it needs to be enforced (see also here). If you say a programmer you should do it, he won’t. Therefore I suggest using OSGi! (But OSGi can become a mess to: 1 2)

Now I discovered a project for modularity in space and satellite design. With CubeSat (10cm x 10cm x 10xm) cubes are used as modules for satellites. It is therefor possible to create 1U, 2U (two cubes) and XU (X cubes) big satellites. Great idea! And it seems to work. Only the reuseability does not seem to work 🙂

Also great it the reduction of cost by using this satellite model. This is also true when using modular designs in software. You can run successful projects within time and resource usage with the right planning, tools and a modular design.

Great blog post, which I should definetly try out sometime…Or it should even be a mandatory hook script!
