In this section you will find EURA NOVA’s latest news and activities.
In this post I will continue to discuss about the IEEE CloudCom conference that I have started in the previous post.
This week I attended the 3rd IEEE International conference on cloud computing Technology and science for presenting our paper about the Elastic Queuing Service. This offers me a new opportunity to give you an overview of hot topics and trends from this conference. As usual I will only give you an overview of the talks I had the chance to attend, since there was a lot of parallel tracks.
In this post we have invited Charles Bonneau, software architect & Eclipse addict at Euranova. Charles will share his feedback from EclipseCon EU 2011. Welcome Charles !
The R&D Department has been very active this academical year 2010-2011 and has organized research activities in association with many academic organizations such as the Université Libre the Bruxelles (ULB-Belgium), the Université Catholique de Louvain (UCl-Belgium) and the University of Tunis El Manar (Tunisia). These collaborations have taken the form of students Master Theses and Master internships.
In total, four Master Theses have been conducted, with 2 students from the ULB and 2 students from the UCl, along with 3 internships with 2 students from the ULB and 1 student from the enginnering faculty of Tunis. Here is a summary of these work:
This year we published a paper in the industrial track of ER 2011 , the annual conference on conceptual modeling research. In this context I spent a couple of days in Brussels at the conference. This gives me the opportunity to share with you an (high level) overview of the trends in this area. Please, notice that this post is only a summary of the discussions I saw and talks I had the chance to see.
As we usually do at the end of the year, we will try to summarize the activities led at EURA NOVA R&D during this year. In this post I come back on our scientific publications we had this year. Those publications cover distributed data storage, model management & governance in finance and, finally, elastic architectures for cloud infrastructures. Let me briefly introduce you those papers.
In this post, I am going on the Research overview started in the last post. Last week I was at the European Business Intelligence Summer School (eBISS 2011) in Paris. The objective was to give a complete overview on the researches and evolution of Bi, viewed by the best of bread researchers and industrials. In this post we continue to describe the main important topics that was exposed.

For newbies in BI, I recommend to start by the wikipedia page (what a collaborative and web 2.0 world !).
In this second part I welcome Nicolas Degroodt who explains how he has extended the YCSB for implementing TPC-C benchmark for NoSQL. In this post we call DBMS a storage framework whether it is RDBMS or a NoSQL.
In this post I would like to speak about two master theses that EURA NOVA is managing with the Faculty of Science Engineering of the Université Libre de Bruxelles (ULB) and with the Université Catholique de Louvain (UCL). The two students have been working on the same topic: the elasticity of data storage on the cloud. The first cool stuff to notice is that they are working on two different aspects of the elasticity by taking different directions, but at the end of the day, by their two contributions they draw a complete picture of the NoSQL benchmarking in the cloud. In this post I will give you a preview of their work that should be published in June 2011.
If we look at the evolution of private cloud, we can clearly see a natural convergence between Data Center Management (DCM) and IaaS management. It is natural because it fits better to the enterprise organization. Let’s be clear, we are talking about large organization, having already data centers for their own IT or businesses. The Services and software department are focusing on the elastic applications they can build on top of the infrastructure management such as Eucalyptus , OpenStack or commercial solutions such as VCloud Director .
Today, we welcome Arthur Lessuise, a student in last year in Master in Computer Science at the Université Libre de Bruxelles (Belgium). He spent 6 weeks at Euranova R&D for its internship. He studied the ability to swap HDFS in Pig Latin by a NoSQL storage. This post is a summary of his amazing work. Enjoy!
I recently had the opportunity to attend the symposium entitled “What’s in a build? Best practice and Requirements” given by Henrik Lindberg (Cloudsmith ) and Nick Boldt (JBoss – RedHat ) at the Eclipse Summit Europe 2010 in Ludwigsburg . The goal was to brainstorm and discuss about the practices and current concerns when it comes to the build of Eclipse plug-ins, features or RCP applications, and the automatic execution of post-build processes such as testing.
This Tuesday 2nd of November, the Eclipse Symposium opened the first afternoon of the ESE 2010 . In this post we will give you an sightsee of the emergent projects presented during the session. The EMF symposium is mainly focus around demos of new projects and initiatives in the modeling world. Going further it gives an overview of the important projects and the next directions of the modeling projects.
Those recent years we have seen the NoSQL initiative emerging against the so-called “old, slow and legacy” relational DBs. But today the debate is extending with a newcomer “The New RDMS architecture”. The concept is simple, the RDMS architecture was developed a long time ago, at that time computer science, computers and processors were extremely different from what we can find today. Why are we not able to gather the recent researches in storage, distributed computing and threading system to re-design a modern RDMS?
During my career, I have seen a lot of companies, especially multi-national companies, being disrupted by internal wars, arguments between departments, jealousy between projects and much more that you can imagine. What’s really impressive after one day assisting at the Red Hat partner summit conferences, is the clear vision, direction and alignment of the whole Red Hat products and projects in the same and unique direction: enterprise, data-centre and cloud.
Sunday 2nd of May, Euranova is at Valencia, Spain, for the Red Hat EMEA partner summit. The ceremony was opened by Jim Whitehurst, the Red Hat CEO in a keynote on the open source opportunity. The key message in the keynote was that every three years we can see an inflexion point in IT, in which business models, technologies and the delivery model completely change. In these last years we have seen this inflexion and arrival of virtualization, cloud and social networking. This keynote described how this point influences the IT and how it brings new challenges. The keynote was organized in three sections: (1) the problem, (2) The Red Hat business and (3) The solution.
Even if the name is really meaningless, the NoSQL defines a new generation of Key/value pair storage. This initiative is gaining popularity but also maturity. The FOSDEM dedicated a complete day and dev. room for this subject. The wikipedia definition defines this movement as: “NoSQL is an umbrella term for a loosely defined class of non-relational data stores that break with a long history of relational databases and ACID guarantees. Data stores that fall under this term may not require fixed table schemas, and usually avoid join operations. The term was first popularised in early 2009. Trends in computer architectures are pressing databases in a direction that requires horizontal scalability. NoSQL-style data stores attempt to address this requirement. Prominent closed-source examples are Google‘s BigTable and Amazon‘s Dynamo. Several open-source variants exist including Facebook‘s Cassandra, Apache HBase, LinkedIn‘s Project Voldemort and many others.”
