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.

How do you look when mergin fails?

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

When was the last time you actually got a CD from your Software vendor?

When was the last time you bought software and got a real CD? Downloads are all around but even more impressing is that Software as a Service (SaaS) is coming. In that case you are not even downloading Software! Amazing isn’t it? But there is a downside of it – this article states that costs for SaaS can add up fast. But traditional software seems to get cheaper.

And now take into account that there are also Open Source solutions around…

The Open Cloud is coming

Randy Bias from GoGrid posted this blog entry earlier today:

Interesting is what he says:

Already there are the inklings of people working on concrete standards including ones for cloud computing infrastructure (Open Cloud Computing Interface (OCCI) a working group of the Open Grid Foundation (OGF)) and the portability of virtual machines (Open Virtualization Format (OVF)). Once these standards are finished and embraced by even a few clouds many customers will opt to choose cloud providers that use them, avoiding vendor lock-in and give choice to customers.

I agree with this statement and hope people will really adopt those standards. Sun is sadly enough not mentioned in the blog-entry. Although not all Cloud Vendors get nice grades .-)
