The WCGA series of workshops purpose is to act as a forum for technical presentations of relevant ongoing research activities in the areas of infrastructure and virtualized infrastructure, services and applications in different areas, bringing together researchers and professionals actively acting in this areas. The workshop also tries to establish multi-institutional collaborative networks and technical and scientific competence groups, as well as to strengthen ongoing activities.

The workshop has been evolving to theme of Clouds since 2010, always approaching large scale computational environments. In 2014, WCGA will reach its 12th edition, get consolidated as one of the main workshops in the area of computer networks and distributed systems. Best paper of the workshop should be invited to a journal special issue.
