Solidifying the foundations of the cloud for the next generation Software Engineering

The Journal of Systems and Software will publish our work entitled “Solidifying the foundations of the cloud for the next generation Software Engineering”. Right now it’s “In Press” state but it can be accessed here.

Infrastructure clouds are expected to play an important role in the next generation Software Engineering but currently there are some drawbacks. These clouds are too infrastructure oriented and they lack advanced service oriented capabilities such as service elasticity, quality of service or admission control to perform a holistic management of a whole application. The deployment of complex multi-tier applications on top of IaaS infrastructures requires to provide the IaaS platforms with an extra service layer that provides advanced service management functionality.

In the present contribution we will introduce the benefits of a cloud based service-oriented architecture, which produces a set of research and scientific challenges. Then, current efforts to face these challenges will be described and finally, some conclusions on the work that still needs to be done at the IaaS level will be provided.

Master Thesis students awarded in Spanish Open Source Contest

One of my Master Thesis student groups has been awarded at the Seventh Edition of CUSL, which stands for “Open-Source University Contest” in Spanish. They were competing against other 84 teams and on 24th May they received the “Best Community Project” prize in a ceremony that took place at the University of Granada.

All the VII CUSL winners. The CygnusCloud team member stand in the second row (left).

The three members of the CygnusCloud team (named in honor of the swam of Complutense University coat of arms) observed that many computational resources of the computer labs spread across the UCM campus were underutilized. On the other hand, computers from our faculty labs are often insufficient to meet the demand.

Turning each campus PC into a Computer Science lab computer would be one way to increase overall computing power, but in reality this isn’t a workable solution given the multitude of software requirements and subsequent administrative overhead this would create.

This project then aims to provide virtual lab machines that can be accessed from any available campus PC in which the both hardware and software requirements are minimal.

CygnusCloud architecture.

An on-demand and centralized distribution of these services like that proposed by CygnusCloud reduces the effects of budget cuts in education as students could use cheaper computers with less energy consumption. The proposed solution increases the academic progress as it optimizes the use of non-specialized computer labs and reduces costs as it relies totally on open source software.

Besides the trophy, my students received a Raspberry Pi development kit. Also, the University of Granada will evaluate CygnusCloud for its integration during next academic year.

Provisioning Data Analytic Workloads in a Cloud

Future Generation Computer Systems has published our work entitled “Provisioning Data Analytic Workloads in a Cloud”, which is the result of the collaboration with Prof. Patrick Martin‘s group from Queen’s University.

Data analytics applications are well-suited for a cloud environment. In this paper we examine the problem of provisioning resources in a public cloud to execute data analytic workloads. The goal of our provisioning method is to determine the most cost-effective configuration for a given data analytic workload. Provisioning a workload in a public cloud environment faces several challenges: it is difficult to develop accurate performance prediction models using standard methods; the space of possible configurations is very large so exact solutions cannot be efficiently determined, and the mix and intensity of query classes in a workload vary dynamically over time.

We provide a formulation of the provisioning problem and then define a framework to solve the problem. Our framework contains a cost model to predict the cost of executing a workload on a configuration and a method of selecting configurations. The cost model balances resource costs and penalties from SLAs. The specific resource demands and frequencies are accounted for by queueing network models of the Virtual Machines (VMs), which are used to predict performance. We evaluate our approach experimentally using sample data analytic workloads on Amazon EC2.

Cloud 4CaaSt’ing in Madrid

This week our project held its General Assembly in Madrid, at IMDEA Software headquarters. In fact, we are very happy to announce that this partner is the latest addition to our consortium.

The IMDEA Software Institute is part of IMDEA, the Madrid Institute of Advanced Studies, a network of international research centers in the Madrid region for research of excellence in areas of high economic impact. Its main focus is to perform the research of excellence required to devise methods that will allow the cost-effective development of software products with sophisticated functionality and high quality.

After 3 days of hard work, surely inspired by the huge amount of clouds that invaded Madrid, we have set a very solid roadmap for the next 6 months.

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.

IaaS Cloud Architecture: From Virtualized Datacenters to Federated Cloud Infrastructures

“IaaS Cloud Architecture: From Virtualized Datacenters to Federated Cloud Infrastructures” is the title of our last article published in the December 2012 issue of the IEEE Computer Magazine that presents an architecture reference model for IaaS clouds. The article introduces the cloud OS (Operating System) platform as the core component of this architecture that is responsible for managing the physical and virtual infrastructure, orchestrating and commanding service provisioning and deployment, and providing federation capabilities for accessing and deploying virtual resources in remote cloud infrastructures. The article ends with a description of different architectures for cloud federation. OpenNebula is also mentioned as an open-source reference implementation of the cloud OS platform.

Enjoy the article!

4CaaSt Passes its Second Year Review!

Last week the 4CaaSt project has been evaluated by the European Commission after its second year.

These 29 months of hard work have produced solid presentations, high quality deliverables and even more important, the integration of components developed within the project. Obviously, the integration of the whole platform is not at 100% (we are just in our second year) but the reviewers were satisfied with the current level.

So long Brussels! We’ll see you next year and we at 4CaaSt promise to bring you something even cooler.

Curiosity, Phobos and Cloud Computing

The Monthly Notices of the Royal Astronomical Society journal has just published our paper entitled “Opportunities to observe solar eclipses by Phobos with the Mars Science Laboratory”. In this contribution a series of predictions for observing solar eclipses by Mars’ biggest moon within NASA’s Mars Science Laboratory (Curiosity) Mission.

The application is a result of the great collaboration that lasts for two years within the MEIGA-MetNet Project, part of the Finnish-Russian-Spanish Mars MetNet Mission which will deploy several meteorological probes on the Martian surface. Phobos shadow trace could be used for the localization of the probes and due to its computing requirements, cloud computing is a “must use” technology.

We already published some papers on this topic, specially on the efficient infrastructure deployment by means of performance and cost. This time, the news are not only that the contribution with proposed observation dates/times for Curiosity was published but also that the Martian rover has confirmed the predictions with the incredible precision of 1 second.

One example of the observations made by Curiosity on Sol 37 (13th September 2012) can be found here.

Summarizing, the application for the next generation of Martian probes has been successfully validated by Curiosity. And of course, cloud computing has become an essential tool for Space exploration.

Cloud 4CaaSt’ing in Paris

The latest General Assembly meeting of the 4CaaSt European Project took place in Paris, where France Telecom headquarters are located.

“The City of the Lights” witnessed a meeting with a more technical profile, as the review for year 2 at the European Commission is approaching. We employed all our time in the preparation of the demo stories that will be shown while integrating the available components (including the clustering features of OpenNebula).

Ingénieur Alexandre Gustave Eiffel must have inspired us, because the outcome of this meeting has been specially great. We are sure that the European Commission reviewers will be astonished with our project!
