Generally, I am interested in networked distributed systems, scalable Internet services, edge cloud computing, cloud and Peer-to-Peer systems, economics based algorithms and systems applied to cloud and peer-to-peer. I am part of the Distributed Systems group.

I participate in a number of research and development projects including:

·         LightKone: A Horizon2020 research project on lightweight computation for networks at the edge. 2017-2019.

·         netCommons: A Horizon2020 research project in the CAPS area, which proposes a novel transdisciplinary methodology on promoting and supporting the creation of network infrastructures as commons. 2016-2018.

·         Cloudy: Cloudy is a distribution based on Debian GNU/Linux, aimed at end users, to foster the adoption of hosting cloud-based services in community network clouds.

·         Erasmus Mundus Joint Doctorate in Distributed Computing EMJD-DC (a 5 year contract starting in 2011/2012).

Other projects that I've been involved with in the past include:

·         Fed4FIRE: A FP7 research project in the FIRE area, which federateds the testbeds developed in individual FIRE projects. UPC has made C-Lab available to Fed4FIRE, which was developed in the CONFINE project.

·         National research project Community Networks and Clouds (TIN2013-47245-C2-1-R) (2014-2016).

·         Scientific coordination of the FP7 FIRE EU CLOMMUNITY project addressing the obstacles for communities of citizens in bootstrapping, running and expanding community-owned networks that provide community services organised as community clouds (2013-2015).

·         FP7 FIRE EU Large-scale integrating project (IP) CONFINE on "Community Networks Testbed for the Future Internet" (10/2011-9/2015).

·         National research project Delfin: Self-adapting distributed systems for the Future Internet (TIN2010-20140-C03-01).

·         FP6 Grid4All: Grid4All aims at enabling domestic users, non-profit organisations such as schools, and small enterprises, to share their resources and to access massive Grid resources when needed, envisioning a future in which access to resources is democratised, readily available, cooperative, and inexpensive (2006-2009).

·         FP6 SORMA: Development of methods and tools for an efficient market-based allocation of resources, through a self-organizing resource management system, using market-driven models supported by extensions for Grid infrastructures. IST European Project (2006-2009).

·         P2PGrid: A national integrated project on several aspects of large scale systems.

·         FP6 Catnets: Evaluation of the Catallaxy paradigm for decentralized operation of dynamic application networks. FET IST European Project (2004-2007).

·         Scientific coordination of FET FP5 Catnet: Catallactic mechanisms for the deployment of application networks on the Internet. (3/2002-3/2003)

·         CRAC: Compartición de Recursos para Aprendizaje Cooperativo (also known as GPPMCLE: Grid and Peer-to-Peer Middleware for Cooperative Learning Environments). MCYT National project (UPC, UOC, UVA) (2002-2005).

·         Cosaco: Components for Cooperative Learning. CICYT National project (UVA, UPC) (2001-2003).


Courses I am currently teaching:

·         Information Technologies Project - a Bachelor-level course (Bachelor Degree in Computing Engineering) on computer networks.

·         Decentralized Systems - a Master-level course (Master in Innovation and Research in Informatics) on distributed, decentralized, scalable systems.

·         Fernando Rodríguez Haro, 2009, Autonomous Management in VM-based Resource Providers. Co-supervised with Leandro Navarro.


Felix Freitag is an associate Professor at the Computer Architecture Department (Departament d'Arquitectura de Computadors) at the Technical University of Catalunya (UPC), which he joined in 1999. He obtained a PhD in Telecommunication Engineering from the UPC in 1998. His research interests include the design of scalable decentralized systems. In the last years his research focused on community clouds. He is member of the IEEE (Institute for Electrical and Electronic Engineers).
