Double date at GridKa School 2015

Next week I’ll be in Karlsruhe (Germany) for this year’s GridKa School edition. This event takes place in Karlsruhe Institute of Technology since 2003.

gridka_logoIf two years ago I gave a talk, this time my participation will be double.

Talk: From Mars to Earth through Cloud Computing

Our society has benefited from Space exploration in many ways. Many of the inventions we use nowadays have their origin in or have been improved by Space research. Computer Science is not an exception.


This talk will introduce the application of Cloud Computing done by me in the context of different Mars missions: Mars MetNet (Spain-Russia-Finland), MSL Curiosity (NASA) and ExoMars2016 (ESA). The achieved know-how allowed the optimization of other areas on Planet Earth, such as weather forecast and agricultural wireless sensor networks processing.

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!

Twenty years of HPC at Cetraro

Every 2 years, The International Advanced Workshop on High Performance Computing, Grids and Clouds (HPC) takes place for shedding some light on key topics in advanced high performance computing systems. From June 25th to 29th experts in the field accomplished this with about forty invited talks.

The venue has been always the same: Gran Hotel San Michele, located at Cetraro, Italy. The hotel shares the charm of the one of the most beautiful places of South Italy.

The founder of this Workshop is Professor Lucio Grandinetti from Università della Calabria. His incredible work and dedication made the best experts to take part of HPC edition after edition.

I had the honor to participate in this event with a talk entitled “Automatic IaaS Elasticity for the PaaS Cloud of the Future where I introduced the 4CaaSt European Commission FP7 project and our work there, providing elasticity at IaaS level. In particular I showed our three approaches: cluster management with the OpenNebula virtual infrastructure manager, a proposal for SLAs and service definition, and finally a set of admission control algorithms.

As explained before, the HPC Workshop started 20 years ago. For this reason we the participants wanted to give Professor Lucio Grandinetti a tribute in the form of a gift. I have to say it was a very emotive moment, and not only for Professor Grandinetti but for all the participants!

Open Source Tools Released by RESERVOIR to Support Cloud Deployment and Usage

Brussels, September 27, 2010 – Are you looking for the delivery of services on an on-demand basis, across countries, at competitive costs and without requiring a large capital investment in infrastructure? Are you interested in the latest technologies in Cloud Computing? RESERVOIR enables the migration of resources across distributed administrative domains, maximizing resource exploitation, and minimizing costs to the end-user with guaranteed quality of service. How does it work? RESERVOIR defines an open federated infrastructure cloud architecture and delivers a framework of open source components you can download from the RESERVOIR website and integrate to build your own open source cloud infrastructure.

Open Source Components

Several key components of the RESERVOIR architecture are being released as open source middleware. The Claudia platform offers a Service Management toolkit to deploy and control the scalability of service among a public, private or hybrid IaaS cloud. It provides a Dashboard and a standard TCloud API based on OVF to support provisioning of PaaS and SaaS. The Claudia platform is available through the Morfeo open source community. The Claudia platform can also be integrated with the OpenNebula cloud management framework.

OpenNebula is an open source toolkit, with excellent performance and scalability to manage tens of thousands of virtual machines, with high integration capabilities to fit into any existing data center, and with the most advanced functionality for building private, public and hybrid clouds. It provides the most common cloud interfaces to expose its functionality for virtual machine, storage and network management The OpenNebula platform is available under Apache license on its community site and on the Morfeo open source community. Explanations are available on how to integrate the Claudia and the OpenNebula platforms.

To help secure the integrated Claudia and OpenNebula platforms, security services are also planned for release on Morfeo. The security services provide access control for the public interfaces of the IaaS cloud, and allow securing an IaaS federation. Role based access control will protect both the Claudia and OpenNebula public interfaces. Role based access control is provided in combination with X509 certificates to provide authorisation, authentication and integrity checks. Security services are also provided to secure the IaaS federation. They allow providing authentication between data centres within a cloud federation, and enforcing global security policies in a federation.

RESERVOIR at ICT2010 – Learn More about these Components Developed for Building Clouds

The RESERVOIR R&D stand called “Deploying Complex Multi-tier Applications on a Federated Cloud Infrastructure” will be placed in the ICT Connects zone of the ICT2010 conference in Brussels on September 27-29, 2010. This exhibit will show, via an interactive demonstration, how complex multi-tier applications can be securely deployed on a federated cloud infrastructure. It will also demonstrate how virtualisation and business service management techniques can be used to manage resources and services on-demand, at competitive costs with a high quality of service. This demonstration will present how RESERVOIR innovation will improve consumers’ accessibility to government and business services. The networking session “Research/Industry Collaboration on Open Source Cloud Middleware” is presented by RESERVOIR in collaboration with SLA@SOI and takes place on September 28, from 11:00 to 12:30. The session aims to identify better ways to collaborate for developing European open source technology for building clouds.

Deltacloud and Libcloud drivers for OpenNebula

A couple of months ago the OpenNebula open-source project established the OpenNebula Ecosystem in order to promote the different tools, extensions and plug-ins that are available to complement OpenNebula from a wide variety of projects, companies, and research centers. These ecosystem components enhance the functionality provided by the OpenNebula Cloud Toolkit or enable its integration with existing products, services and management tools in the virtualization, cloud and data center ecosystems. Recently two new components have been added to the catalog:

A team led by Sebastien Goasguen in Clemson University has also contributed a tool for transferring files to Unix machines on a cluster, this Python tool is able to transfer a 10GB file to 450 hosts in less than one hour. scp-wave tool is of great help when deploying virtualized services on very large-scale infrastructures.

In few weeks the project will announce new tools in the ecosystem, like the support for new cloud APIs (now OpenNebula already supports OCCI and EC2-Query).
