Subject(s):	-Àrees temàtiques de la UPC::Enginyeria de la telecomunicació::Telemàtica i xarxes d'ordinadors -Computer network -Cloud computing -Computational intelligence -Virtual computer systems -The recent advances in fog and edge computing are driving the need to identify what a component at the edge should be. Recognized the wide heterogeneity at the edge -it is with no doubt that different hardware characteristics may be found at the edge devices -thus fueling the need to identify what is the set of resources a potential fog node must have. However -this question is not so easy to answer since some discussions are yet active on what a fog node should be. Beyond the insights about the fog node concept -it looks reasonable and certainly mandatory to overcome the envisioned diversity and heterogeneity at the edge by adopting virtualization as a key strategy to manage resources at the edge. Consequently -in this paper -we analyze possible virtualization strategies -revisit what has been done in cloud computing and discuss potential trends to be deployed in fog computing aligned to the main challenges a tentative fog node is supposed to take over. -Ordinadors, Xarxes d' -Servidors web -Serveis web -Sistemes virtuals (Informàtica)|
