Deviant Abstraction

We have just heard in class in CNAM a speech on distributed applications. Sadly it’s all in French. The speech is about large scale distributed file systems such as SAN or the GFS. We started from NFS to the Google File System.

If this subject interests you, please read the slides. I have left all comments in since my slides were mostly diagrams.

There will be another speech on Internet based DFS. We will design for this event a naive DFS implementation.

It is a lot of work, but really interesting.

Here is a link to a presentation made by JongHong Jeon. He works in South Korean ETRI.

His reflexions are oriented on mobile Web 2.0. He compares the 96 Web to the 06 mobile Web.

One limit on his reflexion: there is obviously a big difference in business models between the Web and Mobile.

For instance, most mobile companies are carrier friendly whereas most most Web companies simply don’t care for ISPs.

There are a lot of new ideas these days and energies in mobile multimedia. However, a lack of standard prevents a real industry to emerge such as what has been seen in the Web.

With all big Web companies entering in this market, is this going to change soon?
