ITIL V3 and SOA

29 10 2008

I attended a seminar about ITIL at London, UK two weeks ago. We discussed a little bit about the new version ITIL v3 and its influence specially in Storage Management and SOA.

I noticed it will probably be very useful for Service Oriented Architecture (SOA) once ITIL v3 is now focusing in service management across the organization and that is exactly what the SOA was developed to do.

About 3 months ago I went to a SOA event at Oracle São Paulo and I found there people working on how was the best way to implement SOA based on ITIL v2. You can implement SOA using ITIL v2 framework, however that was not a framework developed to specially treat services. I believe ITIL v3 launch will improve the SOA Management goading the organization to become more “Service Oriented”.

Let’s see how ITIL v3 will be handled on SOA and Storage Management Projects in the nearly future. There is a good article regarding ITIL v3 and SOA @ http://searchsoa.techtarget.com/news/article/0,,sid26_gci1277548,00.html.

Gmail is not allowed in Germany

12 10 2008

I just arrived in Germany and tried to access my Gmail account. I just got the following message when I typed “www.gmail.com” in the browser.

I searched about this and I realized that one person trademarked the name “G-Mail” in Germany and also resgitered the domain “www.gmail.de”. Okay at this point, I do see any problem once the person registered the domain “www.gmail.de” before Google. That is the way domains register works, first it, first severed!!

However, they also blocked access to “www.gmail.com” (You need to access via http://mail.google.com) for any user connected in the Network of Germany. Yeah, that is not fair!! They are blocking one international site because there is one trademark registered inside the country.

It reminds me the fact of governments trying to control the network. The internet emerged from the society, from the “hacker culture”. Nobody has the total control of this. Lawrence Lessing from Stanford Law School defined that the “Code is the Law”. That means that the only law applied to the cyberspace, to the internet, should be the code. Code means the programs and protocols, like TCP, IP, those protocols that build-up the infrastructure of the internet. In other words, the only law that is applied to internet is defined by the technical protocols.

What did I do? I only changed the proxy! It works!!!

It is one proof that “The code is the law”. The internet was designed in this way and the protocols and softwares allows me to perform that.

Swarmtella – New approach for content distribution

12 10 2008

Last week I attended the seminar “Content Distribution based on Social Swarming” at Cambridge, UK

This exibithion showed a new way to distribute content based on Social Swarming. This technology is called Swarmtella and a comparision against GnuTella showed that it is very efficient increasing the success rate on a search procedure and reducing the bandwidth utilization.

Basically, It works based on Ranking Algorithm that manage the content that a peer can download from the neighbors found on each swarm based on the profiles.

This project is currently supported by CONTENT EU NoE (www.ist-content.eu, BIOGRIDNET Project (www.biogridnet.es), IMDEA Networks Research Institute (www.imdea.org/networks) and NETCOM Research Group at University Carlos III Madrid (www.it.uc3m.es/netcom).

CERN – Datacenter Cooling Technique

11 10 2008

I told in my previous post that I visited CERN Computer Center during the LHC Grid research event at Geneva. One of the most interesting fact I noticed there was the technique used for cooling in the Data Center. They have a lot of physical hardwares that includes, robots storage, disk array and many processors to build-up the TIER-0 of Worldwide LHC Computing Grid.

After many researches about cooling, they realized that the best option to optimize the cooling process and minimize the power consumption was using less than a half of a Rack capacity and also putting the machines as near the floor as possible. To improve the cooling quality they put two racks, one in front of the other and they lock the space between those Racks using glasses. In this case, the cooling was coming from air-conditioner entry located in the floor.

I found it very interesting because usually Data Center Analysts put as many server as the rack can support in other to optimize resources, however that is not the best option for cooling. That’s is a very useful information for cooling problems in a Data Center. I added the photo below taken from the CERN Computer Center:

CERN visit – The founder of the Web

11 10 2008

I visited this week the CERN for the LHC Grid Fest. It is a research event for Grid Computing, the infrastructure used by LHC to process and provide data to many institutions around the world.

Also, CERN was the responsible to create the WEB. In 1991, Tim Berners-Lee at CERN, Geneva, created a language to interconnect computers located in CERN with computers from others research institutions and also this language provided a simple and quick way to access documents around this network.

In 19993, the WEB was becoming famous, many students in the universities created their own “personal page”, basically a simple text page. I cannot forget to mention that the success key for the Web was the creation of software called Mosaic, which allowed the users to create pages using a friendly graphic environment and also provide de ability to add hypermedia, mainly images. Before the WEB, the internet was used mainly by research institutions and it used to require a great ability of the users with many command-line programs. (I would say that those command-lines programs were not created for common users. It requires a specific ability and skill)

Also, CERN is currently the Internet Exchange Point for Switzerland. That means that CERN is responsible to interconnect the Swiss Internet with the World Internet. I visited Computer Centre of CERN in Switzerland and took some photos from their great infrastructure.

From time to time and Pierre Levy

3 10 2008

This week I went to “Musée d’historie des Science” at Geneva. I found there an interesting exhibition “De Temps en Temps” that brings some question about the time in our lives.

First, what is time? Who does have a definition for time?

“What then is time? If no one asks me, I know what it is. If I wish to explain it to him who asks, I do not know”. (Confession, Saint Agustin).

It is clear for us that we know the time, we know it exists but it is very difficult to define its concept. Obviously our lives are measured by any chronological sign, such as, the date, and the hour and those signs are guiding our lives. Nowadays we set a period in the time for each subject in our lives, such as, time to work, time to study, time to have lunch and so on….but it is still hard to define the concept of time.

The exhibition did not try to define the time, it showed some historical techniques from prehistoric until now about how to measure time. It showed us how to measure the time using the Sun, the Moon, even using the atomic clock.

This subject is completely linked with the thought of Pierre Levy on his book “Technologies of Intelligence”. Pierre Levy has written that the technique did not determine the social but the technique can manage this, in other words, Pierre Levy assumes that the technique open new opportunities in the culture. Also, Pierre Levy assumes that the techniques can help to consist a person and the example of time and space is given. Pierre Levy has written that every knowledge we have about time and space is nothing without the techniques. Then, the knowledge we have about the time is only knowledge because we have a technique to measure this, for example, a clock to measure the time. According to Levy, the same also happens with the space, we only know space because we have a map and a certain type of transport to take us from one point in the space to another point, like using a map to traveling from one city to another city.
