Student Cloud Computing Projects against the Financial Crisis

The Master Thesis project is an important stage in which students tackle a specific problem and do so using all available technologies and methodologies learned during their studies.

One of the best features of cloud computing is its high accessibility. In this way, it opens up a world of research possibilities and engenders a fast learning process, allowing the students to develop outstanding projects in a very reasonable time.

This time the effects of the financial crisis turned to be the center of gravity of this year’s Master Thesis projects with I advise, which are always proposed by the students themselves. This year’s projects provide sustainable solutions for Computer Science teaching, Research and High-Tech SMEs.

HPC in the Cloud has featured an article on my students and their awesome projects. Click here to access it.

Also, Cadena SER, one of the major radio stations in Spain, interviewed us in prime time. You can access the audio (in Spanish) here.

Martian Computational Archeology Featured on Datanami

Our latest work in the context of the Mars MetNet mission has been featured on Datanami, an on-line publication devoted to Big Data. This mission brings together Finland, Russia and Spain, aiming to deploy a meteorological network on the Mars surface consisting in several tens of probes.

This time, the challenge has to do with the data gathered  by NASA’s Viking landers 40 years ago. Its re-process will not only aid in the formulation of valid Martian weather models but also to improve the Cloud framework that will be used for the future data from the Mars MetNet probes.

International Workshop on Clouds for Business and Business for Clouds (C4BB4C)

The International Workshop on Clouds for Business and Business for Clouds (C4BB4C) will be held at the 10th IEEE International Symposium on Parallel and Distributed Processing with Applications (ISPA2012).

Cloud Computing has acquired enough maturity to expand its field of application to business. Yet there are not only institutions which use this paradigm in their production line but there are also those which are offering services through the cloud.

This workshop intends to put together efforts done from service producers and consumers in order to make Cloud Computing provide an added value to the economy of any kind of institution. Technologies, policies and heuristics will be shared, not discarding those coming from other areas that would benefit Cloud Computing.

The Workshop intends also to focus on how services are delivered through the cloud as a popular strategic technology choice for businesses that provides a flexible, ubiquitous and consistent platform accessible from anywhere at any time.

The interface of software services and cloud computing provides a rich area for research and experience to give a unique insight into how cloud-based service can be achieved in practice. We encourage submissions of research papers on work in the area of Cloud Computing, Service Engineering, and especially welcome papers describing developments in cloud-enabled business process management and all related areas, such as deployment techniques, business models for cloud-based enterprises and experience reports from practitioners.

Extended version of selected papers will be included in a special issue of Scientific Computing: Practice and Experience.

This Workshop couldn’t be possible without the following projects: MEDIANET (Comunidad de Madrid S2009/TIC-1468), HPCcloud (MICINN TIN2009-07146) and 4CaaSt (Gr. Agree. 258862).

Will you let the Sky fall down?

Cloud computing has moved the center of gravity of application distributed execution, by exploiting virtualization at different layers and by adding a complexity level to the scheduling problem. Our dependability on this paradigm has increased to the point where our vital services pertaining to the research, industry or even lifestyle domain have been massively moved onto cloud infrastructures.

Then, what happens when the sky falls down?

In order to provide answers, I am co-chairing with Prof. Rafael Tolosana-Calasanz and Prof. José Ángel Bañares the First International Workshop on fault Tolerant Architectures for Reliable Distributed Infrastructures and Services (TARDIS2011). Also, Prof. Eduardo Huedo is serving at the Program Committee. This workshop will take place in Melbourne (Australia) during the 4th IEEE International Conference on Utility and Cloud Computing (UCC 2011), on 5-8 December 2011.

The paper submission system is open and these are the important dates:

  • Deadline for submissions: 17 July 2011
  • Acceptance notification: 30 August 2011
  • Deadline for camera ready contributions: 25 September 2011
Additionally, “HPC in the Cloud” has featured an article on fault tolerance in Clouds mentioning TARDIS2011:

In the last issue of IEEE Internet Computing, Dejan Milojicic, editor in chief of Computing Now, discusses cloud computing and OpenNebula with Ignacio M. Llorente and Rubén S. Montero, leads of the open source OpenNebula project. The video is available online in the Trend Wars section at the Computing Now site and the transcript has been published in the March/April issue of IEEE Internet Computing.


BonFIRE is a 8,5-million-Euro EU-funded initiative (EU grant agreement 257386) funded by the 7th FWP (Seventh Framework Programme) under the Future Internet Experimental Facility and Experimentally-driven Research (ICT-2009.1.6) area, aimed at designing, building and operating a multi-site cloud facility to support applications, services and systems research targeting the Internet of Services community within the Future Internet.

BonFIRE will operate a Cloud facility based on an Infrastructure as a Service delivery model with guidelines, policies and best practices for experimentation. BonFIRE will adopt a federated multi-platform approach providing interconnection and interoperation between novel service and networking testbeds. The platform will offer advanced services and tools for services research including cloud federation, virtual machine management, service modelling, service lifecycle management, service level agreements, quality of service monitoring and analytics.

DSA-Research will join a consortium of world leading industrial and academic organisations in cloud computing to deliver a robust, reliable and sustainable facility for large scale experimentally-driven cloud research. Multinational companies (ATOS, HP, SAP), renowned universities and super computing centres (EPCC, HLRS Stuttgart, IBBT, TUB), research centres (IT Innovation, FhG Fokus, INRIA, i2CAT) and technology analysts (451 Group) provide the complimentary expertise and infrastructure resources necessary to accelerate the research and development within the Internet of Services community.

This news consolidates DSA-Research’s position at the cutting edge of cloud computing research worldwide, following two recent announcements of its participation in the EU’s StratusLab project, aimed at bringing cloud and virtualization to grid computing, and its participation in the EU’s 4CaaSt project, aimed at building the PaaS cloud of the future.
